 “A substantive, thorough, sophisticated literature review is a precondition for doing substantive, thorough, sophisticated research”. Boote and Baile 2005

Authors of manuscripts treat writing a literature review as a routine work or a mere formality. But a seasoned one knows the purpose and importance of a well-written literature review.  Since it is one of the basic needs for researches at any level, they have to be done vigilantly. Only then the reader will know that the basics of research have not been neglected.

Importance of Literature Review In Research

The aim of any literature review is to summarize and synthesize the arguments and ideas of existing knowledge in a particular field without adding any new contributions.   Being built on existing knowledge they help the researcher to even turn the wheels of the topic of research.  It is possible only with profound knowledge of what is wrong in the existing findings in detail to overpower them.  For other researches, the literature review gives the direction to be headed for its success. 

The common perception of literature review and reality:

As per the common belief, literature reviews are only a summary of the sources related to the research. And many authors of scientific manuscripts believe that they are only surveys of what are the researches are done on the chosen topic.  But on the contrary, it uses published information from pertinent and relevant sources like

  • Scholarly books
  • Scientific papers
  • Latest studies in the field
  • Established school of thoughts
  • Relevant articles from renowned scientific journals

and many more for a field of study or theory or a particular problem to do the following:

  • Summarize into a brief account of all information
  • Synthesize the information by restructuring and reorganizing
  • Critical evaluation of a concept or a school of thought or ideas
  • Familiarize the authors to the extent of knowledge in the particular field
  • Encapsulate
  • Compare & contrast

By doing the above on the relevant information, it provides the reader of the scientific manuscript with the following for a better understanding of it:

  • It establishes the authors’  in-depth understanding and knowledge of their field subject
  • It gives the background of the research
  • Portrays the scientific manuscript plan of examining the research result
  • Illuminates on how the knowledge has changed within the field
  • Highlights what has already been done in a particular field
  • Information of the generally accepted facts, emerging and current state of the topic of research
  • Identifies the research gap that is still unexplored or under-researched fields
  • Demonstrates how the research fits within a larger field of study
  • Provides an overview of the sources explored during the research of a particular topic

Importance of literature review in research:

The importance of literature review in scientific manuscripts can be condensed into an analytical feature to enable the multifold reach of its significance.  It adds value to the legitimacy of the research in many ways:

  • Provides the interpretation of existing literature in light of updated developments in the field to help in establishing the consistency in knowledge and relevancy of existing materials
  • It helps in calculating the impact of the latest information in the field by mapping their progress of knowledge.
  • It brings out the dialects of contradictions between various thoughts within the field to establish facts
  • The research gaps scrutinized initially are further explored to establish the latest facts of theories to add value to the field
  • Indicates the current research place in the schema of a particular field
  • Provides information for relevancy and coherency to check the research
  • Apart from elucidating the continuance of knowledge, it also points out areas that require further investigation and thus aid as a starting point of any future research
  • Justifies the research and sets up the research question
  • Sets up a theoretical framework comprising the concepts and theories of the research upon which its success can be judged
  • Helps to adopt a more appropriate methodology for the research by examining the strengths and weaknesses of existing research in the same field
  • Increases the significance of the results by comparing it with the existing literature
  • Provides a point of reference by writing the findings in the scientific manuscript
  • Helps to get the due credit from the audience for having done the fact-finding and fact-checking mission in the scientific manuscripts
  • The more the reference of relevant sources of it could increase more of its trustworthiness with the readers
  • Helps to prevent plagiarism by tailoring and uniquely tweaking the scientific manuscript not to repeat other’s original idea
  • By preventing plagiarism , it saves the scientific manuscript from rejection and thus also saves a lot of time and money
  • Helps to evaluate, condense and synthesize gist in the author’s own words to sharpen the research focus
  • Helps to compare and contrast to  show the originality and uniqueness of the research than that of the existing other researches
  • Rationalizes the need for conducting the particular research in a specified field
  • Helps to collect data accurately for allowing any new methodology of research than the existing ones
  • Enables the readers of the manuscript to answer the following questions of its readers for its better chances for publication
  • What do the researchers know?
  • What do they not know?
  • Is the scientific manuscript reliable and trustworthy?
  • What are the knowledge gaps of the researcher?

22. It helps the readers to identify the following for further reading of the scientific manuscript:

  • What has been already established, discredited and accepted in the particular field of research
  • Areas of controversy and conflicts among different schools of thought
  • Unsolved problems and issues in the connected field of research
  • The emerging trends and approaches
  • How the research extends, builds upon and leaves behind from the previous research

A profound literature review with many relevant sources of reference will enhance the chances of the scientific manuscript publication in renowned and reputed scientific journals .

What is a literature review?

A literature review is an integrated analysis -- not just a summary-- of scholarly writings and other relevant evidence related directly to your research question.  That is, it represents a synthesis of the evidence that provides background information on your topic and shows a association between the evidence and your research question.

A literature review may be a stand alone work or the introduction to a larger research paper, depending on the assignment.  Rely heavily on the guidelines your instructor has given you.

Why is it important?

A literature review is important because it:

  • Explains the background of research on a topic.
  • Demonstrates why a topic is significant to a subject area.
  • Discovers relationships between research studies/ideas.
  • Identifies major themes, concepts, and researchers on a topic.
  • Identifies critical gaps and points of disagreement.
  • Discusses further research questions that logically come out of the previous studies.

APA Style Blog - for those harder to find answers

1. Choose a topic. Define your research question.

Your literature review should be guided by your central research question.  The literature represents background and research developments related to a specific research question, interpreted and analyzed by you in a synthesized way.

  • Make sure your research question is not too broad or too narrow.  Is it manageable?
  • Begin writing down terms that are related to your question. These will be useful for searches later.
  • If you have the opportunity, discuss your topic with your professor and your class mates.

2. Decide on the scope of your review

How many studies do you need to look at? How comprehensive should it be? How many years should it cover? 

  • This may depend on your assignment.  How many sources does the assignment require?

3. Select the databases you will use to conduct your searches.

Make a list of the databases you will search. 

Where to find databases:

  • use the tabs on this guide
  • Find other databases in the Nursing Information Resources web page
  • More on the Medical Library web page
  • ... and more on the Yale University Library web page

4. Conduct your searches to find the evidence. Keep track of your searches.

  • Use the key words in your question, as well as synonyms for those words, as terms in your search. Use the database tutorials for help.
  • Save the searches in the databases. This saves time when you want to redo, or modify, the searches. It is also helpful to use as a guide is the searches are not finding any useful results.
  • Review the abstracts of research studies carefully. This will save you time.
  • Use the bibliographies and references of research studies you find to locate others.
  • Check with your professor, or a subject expert in the field, if you are missing any key works in the field.
  • Ask your librarian for help at any time.
  • Use a citation manager, such as EndNote as the repository for your citations. See the EndNote tutorials for help.

Review the literature

Some questions to help you analyze the research:

  • What was the research question of the study you are reviewing? What were the authors trying to discover?
  • Was the research funded by a source that could influence the findings?
  • What were the research methodologies? Analyze its literature review, the samples and variables used, the results, and the conclusions.
  • Does the research seem to be complete? Could it have been conducted more soundly? What further questions does it raise?
  • If there are conflicting studies, why do you think that is?
  • How are the authors viewed in the field? Has this study been cited? If so, how has it been analyzed?

Tips: 

  • Review the abstracts carefully.  
  • Keep careful notes so that you may track your thought processes during the research process.
  • Create a matrix of the studies for easy analysis, and synthesis, across all of the studies.

Literature Review in Research Proposal: A Comprehensive Guide

literature review in research proposal

  • Introduction: What is a Literature Review and Why is it Important?

The introduction is an essential part of any literature review in a research proposal. It provides a foundation for the entire review and gives context to the importance of conducting a literature review in the first place. In this section, you will need to provide a brief definition of what a literature review is and why it is an essential component of a research proposal.

A literature review is a critical evaluation and summary of published research studies and other sources relevant to a particular research topic. The purpose of a literature review is to identify and evaluate the existing knowledge on a topic, as well as to identify any gaps in the knowledge base that the proposed research aims to fill.

In a research proposal, the introduction section must explain the importance of the literature review to the overall project. It is an opportunity to convince the reader of the significance of the research problem and to show how the literature review will contribute to knowledge building. This section should also provide a clear and concise statement of the research problem and the research question(s).

Overall, the introduction section sets the stage for the literature review and the research proposal as a whole. It provides a context for the research problem, highlights the knowledge gaps that the proposed research aims to fill, and justifies the importance of the literature review in achieving the research objectives. By providing a clear and compelling introduction, researchers can ensure that their proposal has a strong foundation for success.

Subheading 2, “Defining the Research Problem: Using Literature Review to Identify Gaps in Knowledge,” is an important subheading in the literature review section of a research proposal. A literature review is an essential part of any research project as it provides a comprehensive overview of the existing body of knowledge on a specific research topic.

To define the research problem, it is crucial to identify what is already known and what is not known about the research topic. This is where a literature review comes in handy. This process of identifying gaps in knowledge allows the researcher to identify the specific research problem and develop research questions and objectives that can address those gaps.

In summary, subheading 2 is critical in the literature review section of a research proposal as it highlights the importance of using a literature review to identify gaps in knowledge and define the research problem.

The subheading “Developing a Research Question: Using Literature Review to Inform Research Questions and Objectives” highlights the crucial role of literature review in guiding the development of research questions and objectives. A well-formulated research question provides a clear focus for the study, ensuring that the research stays on track and avoids any unnecessary or irrelevant work. In addition, by conducting a thorough literature review, researchers can identify the current state of knowledge on the topic, recognize any gaps or inconsistencies in the literature, and identify potential areas of further exploration.

To develop a research question, it is important to first consider the research problem and the purpose of the study. Once the problem has been defined, the literature review can help to identify relevant theoretical and empirical frameworks that can inform the development of research questions. The literature review can also help to refine and narrow the research question, ensuring that it is feasible, relevant, and important.

The fourth subheading, “Conducting a Literature Search: Tips and Strategies for Finding Relevant Studies and Sources,” is an essential aspect of writing a comprehensive literature review for a research proposal. The literature search is a critical step in identifying relevant studies and sources that will help answer the research question and objectives.

When conducting a literature search, it is crucial to develop a systematic approach that will guide the process.

In addition, it is important to document the search process by keeping a record of the keywords used, the sources searched, and the search results. This documentation will enable researchers to retrace their steps if necessary and ensure that they are transparent in their research methods.

Another important consideration when conducting a literature search is the quality of the sources used. Researchers should be mindful of the credibility of the sources and ensure that they are peer-reviewed, reputable, and relevant to the research question. Using sources that are not reliable or relevant can weaken the literature review and the overall research proposal.

Subheading 5, “Analyzing and Synthesizing Literature: Methods for Summarizing and Integrating Findings,” is a critical component of any literature review in a research proposal. This subheading refers to the process of reviewing and synthesizing existing research to gain an understanding of the current state of knowledge on the research topic.

In the analysis and synthesis phase, the researcher begins by reviewing the literature collected in the search phase. This process involves reading through each article or source, summarizing the main findings, and noting the key points that contribute to the understanding of the research problem. The researcher may use a variety of methods to organize the information, such as tables, charts, or diagrams.

Once the researcher has completed the summary of each study, the synthesis phase begins. This is the process of integrating the findings from the individual studies into a cohesive whole. The researcher must identify commonalities and differences between the studies and identify themes and patterns that emerge across the literature.

Subheading 6, “Evaluating the Quality of Literature: Criteria for Assessing the Validity and Reliability of Studies,” is a crucial element of any literature review in a research proposal. Evaluating the quality of literature is an essential step in ensuring that the information gathered from various sources is trustworthy and accurate.

To evaluate the quality of literature, researchers must use established criteria that are specific to the research topic and questions. For example, when conducting research in the social sciences, the criteria may include the validity of the research design, the reliability of the data collection methods, and the transparency of the analysis. In contrast, when researching in the natural sciences, the criteria may include the accuracy of the measurements, the statistical analysis, and the experimental design.

One way to evaluate the quality of literature is to use a systematic review approach. Systematic reviews involve a thorough and structured process of searching, evaluating, and synthesizing existing research to answer specific research questions. This approach ensures that the quality of the literature is assessed in a rigorous and transparent way, which increases the confidence in the findings of the literature review.

Subheading 7, “Identifying Themes and Patterns: Techniques for Identifying Common Themes and Patterns Across Studies,” is an important aspect of conducting a literature review in a research proposal. After conducting a thorough literature search and analyzing and synthesizing the findings, researchers need to identify the common themes and patterns that emerge across different studies. Furthermore, this process is essential because it helps to build a solid foundation for the proposed research by identifying existing knowledge gaps and areas where further research is needed.

One technique for identifying themes and patterns is to use a thematic analysis approach. Thematic analysis involves reading through the literature and highlighting or coding relevant data that relates to the research question or objective. Once all of the data has been coded, researchers can then categorize the codes into themes, which can be used to summarize the key findings of the literature review.

Another technique for identifying themes and patterns is to use a meta-synthesis approach. Meta-synthesis involves synthesizing the findings of multiple studies and identifying common themes and patterns that emerge.

In conclusion, a literature review is an essential component of any research proposal, and its importance cannot be overstated. The literature review helps to identify existing knowledge gaps, inform research questions and objectives, and build a solid foundation for the proposed research. In addition, by conducting a thorough literature search, analyzing and synthesizing the findings, and identifying common themes and patterns, researchers can ensure that their literature review is comprehensive and relevant to their research objectives.

What is a Literature Review?

So, what is a literature review .

"A literature review is an account of what has been published on a topic by accredited scholars and researchers. In writing the literature review, your purpose is to convey to your reader what knowledge and ideas have been established on a topic, and what their strengths and weaknesses are. As a piece of writing, the literature review must be defined by a guiding concept (e.g., your research objective, the problem or issue you are discussing, or your argumentative thesis). It is not just a descriptive list of the material available or a set of summaries." - Quote from Taylor, D. (n.d)."The Literature Review: A Few Tips on Conducting it".

  • Citation: "The Literature Review: A Few Tips on Conducting it"

What kinds of literature reviews are written?

Each field has a particular way to do reviews for academic research literature. In the social sciences and humanities the most common are:

  • Narrative Reviews: The purpose of this type of review is to describe the current state of the research on a specific research topic and to offer a critical analysis of the literature reviewed. Studies are grouped by research/theoretical categories, and themes and trends, strengths and weaknesses, and gaps are identified. The review ends with a conclusion section that summarizes the findings regarding the state of the research of the specific study, the gaps identify and if applicable, explains how the author's research will address gaps identify in the review and expand the knowledge on the topic reviewed.
  • Book review essays/ Historiographical review essays : A type of literature review typical in History and related fields, e.g., Latin American studies. For example, the Latin American Research Review explains that the purpose of this type of review is to “(1) to familiarize readers with the subject, approach, arguments, and conclusions found in a group of books whose common focus is a historical period; a country or region within Latin America; or a practice, development, or issue of interest to specialists and others; (2) to locate these books within current scholarship, critical methodologies, and approaches; and (3) to probe the relation of these new books to previous work on the subject, especially canonical texts. Unlike individual book reviews, the cluster reviews found in LARR seek to address the state of the field or discipline and not solely the works at issue.” - LARR

What are the Goals of Creating a Literature Review?

  • To develop a theory or evaluate an existing theory
  • To summarize the historical or existing state of a research topic
  • Identify a problem in a field of research 
  • Baumeister, R.F. & Leary, M.R. (1997). "Writing narrative literature reviews," Review of General Psychology , 1(3), 311-320.

When do you need to write a Literature Review?

  • When writing a prospectus or a thesis/dissertation
  • When writing a research paper
  • When writing a grant proposal

In all these cases you need to dedicate a chapter in these works to showcase what has been written about your research topic and to point out how your own research will shed new light into a body of scholarship.

Where I can find examples of Literature Reviews?

Note:  In the humanities, even if they don't use the term "literature review", they may have a dedicated  chapter that reviewed the "critical bibliography" or they incorporated that review in the introduction or first chapter of the dissertation, book, or article.

A sophisticated literature review (LR) can result in a robust dissertation/thesis by scrutinizing the main problem examined by the academic study; anticipating research hypotheses, methods and results; and maintaining the interest of the audience in how the dissertation/thesis will provide solutions for the current gaps in a particular field. Unfortunately, little guidance is available on elaborating LRs, and writing an LR chapter is not a linear process. An LR translates students’ abilities in information literacy, the language domain, and critical writing. Students in postgraduate programs should be systematically trained in these skills. Therefore, this paper discusses the purposes of LRs in dissertations and theses. Second, the paper considers five steps for developing a review: defining the main topic, searching the literature, analyzing the results, writing the review and reflecting on the writing. Ultimately, this study proposes a twelve-item LR checklist. By clearly stating the desired achievements, this checklist allows Masters and Ph.D. students to continuously assess their own progress in elaborating an LR. Institutions aiming to strengthen students’ necessary skills in critical academic writing should also use this tool.

INTRODUCTION

Writing the literature review (LR) is often viewed as a difficult task that can be a point of writer’s block and procrastination ( 1 ) in postgraduate life. Disagreements on the definitions or classifications of LRs ( 2 ) may confuse students about their purpose and scope, as well as how to perform an LR. Interestingly, at many universities, the LR is still an important element in any academic work, despite the more recent trend of producing scientific articles rather than classical theses.

The LR is not an isolated section of the thesis/dissertation or a copy of the background section of a research proposal. It identifies the state-of-the-art knowledge in a particular field, clarifies information that is already known, elucidates implications of the problem being analyzed, links theory and practice ( 3 - 5 ), highlights gaps in the current literature, and places the dissertation/thesis within the research agenda of that field. Additionally, by writing the LR, postgraduate students will comprehend the structure of the subject and elaborate on their cognitive connections ( 3 ) while analyzing and synthesizing data with increasing maturity.

At the same time, the LR transforms the student and hints at the contents of other chapters for the reader. First, the LR explains the research question; second, it supports the hypothesis, objectives, and methods of the research project; and finally, it facilitates a description of the student’s interpretation of the results and his/her conclusions. For scholars, the LR is an introductory chapter ( 6 ). If it is well written, it demonstrates the student’s understanding of and maturity in a particular topic. A sound and sophisticated LR can indicate a robust dissertation/thesis.

A consensus on the best method to elaborate a dissertation/thesis has not been achieved. The LR can be a distinct chapter or included in different sections; it can be part of the introduction chapter, part of each research topic, or part of each published paper ( 7 ). However, scholars view the LR as an integral part of the main body of an academic work because it is intrinsically connected to other sections ( Figure 1 ) and is frequently present. The structure of the LR depends on the conventions of a particular discipline, the rules of the department, and the student’s and supervisor’s areas of expertise, needs and interests.

Interestingly, many postgraduate students choose to submit their LR to peer-reviewed journals. As LRs are critical evaluations of current knowledge, they are indeed publishable material, even in the form of narrative or systematic reviews. However, systematic reviews have specific patterns 1 ( 8 ) that may not entirely fit with the questions posed in the dissertation/thesis. Additionally, the scope of a systematic review may be too narrow, and the strict criteria for study inclusion may omit important information from the dissertation/thesis. Therefore, this essay discusses the definition of an LR is and methods to develop an LR in the context of an academic dissertation/thesis. Finally, we suggest a checklist to evaluate an LR.

WHAT IS A LITERATURE REVIEW IN A THESIS?

Conducting research and writing a dissertation/thesis translates rational thinking and enthusiasm ( 9 ). While a strong body of literature that instructs students on research methodology, data analysis and writing scientific papers exists, little guidance on performing LRs is available. The LR is a unique opportunity to assess and contrast various arguments and theories, not just summarize them. The research results should not be discussed within the LR, but the postgraduate student tends to write a comprehensive LR while reflecting on his or her own findings ( 10 ).

Many people believe that writing an LR is a lonely and linear process. Supervisors or the institutions assume that the Ph.D. student has mastered the relevant techniques and vocabulary associated with his/her subject and conducts a self-reflection about previously published findings. Indeed, while elaborating the LR, the student should aggregate diverse skills, which mainly rely on his/her own commitment to mastering them. Thus, less supervision should be required ( 11 ). However, the parameters described above might not currently be the case for many students ( 11 , 12 ), and the lack of formal and systematic training on writing LRs is an important concern ( 11 ).

An institutional environment devoted to active learning will provide students the opportunity to continuously reflect on LRs, which will form a dialogue between the postgraduate student and the current literature in a particular field ( 13 ). Postgraduate students will be interpreting studies by other researchers, and, according to Hart (1998) ( 3 ), the outcomes of the LR in a dissertation/thesis include the following:

  • To identify what research has been performed and what topics require further investigation in a particular field of knowledge;
  • To determine the context of the problem;
  • To recognize the main methodologies and techniques that have been used in the past;
  • To place the current research project within the historical, methodological and theoretical context of a particular field;
  • To identify significant aspects of the topic;
  • To elucidate the implications of the topic;
  • To offer an alternative perspective;
  • To discern how the studied subject is structured;
  • To improve the student’s subject vocabulary in a particular field; and
  • To characterize the links between theory and practice.

A sound LR translates the postgraduate student’s expertise in academic and scientific writing: it expresses his/her level of comfort with synthesizing ideas ( 11 ). The LR reveals how well the postgraduate student has proceeded in three domains: an effective literature search, the language domain, and critical writing.

Effective literature search

All students should be trained in gathering appropriate data for specific purposes, and information literacy skills are a cornerstone. These skills are defined as “an individual’s ability to know when they need information, to identify information that can help them address the issue or problem at hand, and to locate, evaluate, and use that information effectively” ( 14 ). Librarian support is of vital importance in coaching the appropriate use of Boolean logic (AND, OR, NOT) and other tools for highly efficient literature searches (e.g., quotation marks and truncation), as is the appropriate management of electronic databases.

Language domain

Academic writing must be concise and precise: unnecessary words distract the reader from the essential content ( 15 ). In this context, reading about issues distant from the research topic ( 16 ) may increase students’ general vocabulary and familiarity with grammar. Ultimately, reading diverse materials facilitates and encourages the writing process itself.

Critical writing

Critical judgment includes critical reading, thinking and writing. It supposes a student’s analytical reflection about what he/she has read. The student should delineate the basic elements of the topic, characterize the most relevant claims, identify relationships, and finally contrast those relationships ( 17 ). Each scientific document highlights the perspective of the author, and students will become more confident in judging the supporting evidence and underlying premises of a study and constructing their own counterargument as they read more articles. A paucity of integration or contradictory perspectives indicates lower levels of cognitive complexity ( 12 ).

Thus, while elaborating an LR, the postgraduate student should achieve the highest category of Bloom’s cognitive skills: evaluation ( 12 ). The writer should not only summarize data and understand each topic but also be able to make judgments based on objective criteria, compare resources and findings, identify discrepancies due to methodology, and construct his/her own argument ( 12 ). As a result, the student will be sufficiently confident to show his/her own voice .

Writing a consistent LR is an intense and complex activity that reveals the training and long-lasting academic skills of a writer. It is not a lonely or linear process. However, students are unlikely to be prepared to write an LR if they have not mastered the aforementioned domains ( 10 ). An institutional environment that supports student learning is crucial.

Different institutions employ distinct methods to promote students’ learning processes. First, many universities propose modules to develop behind the scenes activities that enhance self-reflection about general skills (e.g., the skills we have mastered and the skills we need to develop further), behaviors that should be incorporated (e.g., self-criticism about one’s own thoughts), and each student’s role in the advancement of his/her field. Lectures or workshops about LRs themselves are useful because they describe the purposes of the LR and how it fits into the whole picture of a student’s work. These activities may explain what type of discussion an LR must involve, the importance of defining the correct scope, the reasons to include a particular resource, and the main role of critical reading.

Some pedagogic services that promote a continuous improvement in study and academic skills are equally important. Examples include workshops about time management, the accomplishment of personal objectives, active learning, and foreign languages for nonnative speakers. Additionally, opportunities to converse with other students promotes an awareness of others’ experiences and difficulties. Ultimately, the supervisor’s role in providing feedback and setting deadlines is crucial in developing students’ abilities and in strengthening students’ writing quality ( 12 ).

HOW SHOULD A LITERATURE REVIEW BE DEVELOPED?

A consensus on the appropriate method for elaborating an LR is not available, but four main steps are generally accepted: defining the main topic, searching the literature, analyzing the results, and writing ( 6 ). We suggest a fifth step: reflecting on the information that has been written in previous publications ( Figure 2 ).

First step: Defining the main topic

Planning an LR is directly linked to the research main question of the thesis and occurs in parallel to students’ training in the three domains discussed above. The planning stage helps organize ideas, delimit the scope of the LR ( 11 ), and avoid the wasting of time in the process. Planning includes the following steps:

  • Reflecting on the scope of the LR: postgraduate students will have assumptions about what material must be addressed and what information is not essential to an LR ( 13 , 18 ). Cooper’s Taxonomy of Literature Reviews 2 systematizes the writing process through six characteristics and nonmutually exclusive categories. The focus refers to the reviewer’s most important points of interest, while the goals concern what students want to achieve with the LR. The perspective assumes answers to the student’s own view of the LR and how he/she presents a particular issue. The coverage defines how comprehensive the student is in presenting the literature, and the organization determines the sequence of arguments. The audience is defined as the group for whom the LR is written.
  • Designating sections and subsections: Headings and subheadings should be specific, explanatory and have a coherent sequence throughout the text ( 4 ). They simulate an inverted pyramid, with an increasing level of reflection and depth of argument.
  • Identifying keywords: The relevant keywords for each LR section should be listed to guide the literature search. This list should mirror what Hart (1998) ( 3 ) advocates as subject vocabulary . The keywords will also be useful when the student is writing the LR since they guide the reader through the text.
  • Delineating the time interval and language of documents to be retrieved in the second step. The most recently published documents should be considered, but relevant texts published before a predefined cutoff year can be included if they are classic documents in that field. Extra care should be employed when translating documents.

Second step: Searching the literature

The ability to gather adequate information from the literature must be addressed in postgraduate programs. Librarian support is important, particularly for accessing difficult texts. This step comprises the following components:

  • Searching the literature itself: This process consists of defining which databases (electronic or dissertation/thesis repositories), official documents, and books will be searched and then actively conducting the search. Information literacy skills have a central role in this stage. While searching electronic databases, controlled vocabulary (e.g., Medical Subject Headings, or MeSH, for the PubMed database) or specific standardized syntax rules may need to be applied.

In addition, two other approaches are suggested. First, a review of the reference list of each document might be useful for identifying relevant publications to be included and important opinions to be assessed. This step is also relevant for referencing the original studies and leading authors in that field. Moreover, students can directly contact the experts on a particular topic to consult with them regarding their experience or use them as a source of additional unpublished documents.

Before submitting a dissertation/thesis, the electronic search strategy should be repeated. This process will ensure that the most recently published papers will be considered in the LR.

  • Selecting documents for inclusion: Generally, the most recent literature will be included in the form of published peer-reviewed papers. Assess books and unpublished material, such as conference abstracts, academic texts and government reports, are also important to assess since the gray literature also offers valuable information. However, since these materials are not peer-reviewed, we recommend that they are carefully added to the LR.

This task is an important exercise in time management. First, students should read the title and abstract to understand whether that document suits their purposes, addresses the research question, and helps develop the topic of interest. Then, they should scan the full text, determine how it is structured, group it with similar documents, and verify whether other arguments might be considered ( 5 ).

Third step: Analyzing the results

Critical reading and thinking skills are important in this step. This step consists of the following components:

  • Reading documents: The student may read various texts in depth according to LR sections and subsections ( defining the main topic ), which is not a passive activity ( 1 ). Some questions should be asked to practice critical analysis skills, as listed below. Is the research question evident and articulated with previous knowledge? What are the authors’ research goals and theoretical orientations, and how do they interact? Are the authors’ claims related to other scholars’ research? Do the authors consider different perspectives? Was the research project designed and conducted properly? Are the results and discussion plausible, and are they consistent with the research objectives and methodology? What are the strengths and limitations of this work? How do the authors support their findings? How does this work contribute to the current research topic? ( 1 , 19 )
  • Taking notes: Students who systematically take notes on each document are more readily able to establish similarities or differences with other documents and to highlight personal observations. This approach reinforces the student’s ideas about the next step and helps develop his/her own academic voice ( 1 , 13 ). Voice recognition software ( 16 ), mind maps ( 5 ), flowcharts, tables, spreadsheets, personal comments on the referenced texts, and note-taking apps are all available tools for managing these observations, and the student him/herself should use the tool that best improves his/her learning. Additionally, when a student is considering submitting an LR to a peer-reviewed journal, notes should be taken on the activities performed in all five steps to ensure that they are able to be replicated.

Fourth step: Writing

The recognition of when a student is able and ready to write after a sufficient period of reading and thinking is likely a difficult task. Some students can produce a review in a single long work session. However, as discussed above, writing is not a linear process, and students do not need to write LRs according to a specific sequence of sections. Writing an LR is a time-consuming task, and some scholars believe that a period of at least six months is sufficient ( 6 ). An LR, and academic writing in general, expresses the writer’s proper thoughts, conclusions about others’ work ( 6 , 10 , 13 , 16 ), and decisions about methods to progress in the chosen field of knowledge. Thus, each student is expected to present a different learning and writing trajectory.

In this step, writing methods should be considered; then, editing, citing and correct referencing should complete this stage, at least temporarily. Freewriting techniques may be a good starting point for brainstorming ideas and improving the understanding of the information that has been read ( 1 ). Students should consider the following parameters when creating an agenda for writing the LR: two-hour writing blocks (at minimum), with prespecified tasks that are possible to complete in one section; short (minutes) and long breaks (days or weeks) to allow sufficient time for mental rest and reflection; and short- and long-term goals to motivate the writing itself ( 20 ). With increasing experience, this scheme can vary widely, and it is not a straightforward rule. Importantly, each discipline has a different way of writing ( 1 ), and each department has its own preferred styles for citations and references.

Fifth step: Reflecting on the writing

In this step, the postgraduate student should ask him/herself the same questions as in the analyzing the results step, which can take more time than anticipated. Ambiguities, repeated ideas, and a lack of coherence may not be noted when the student is immersed in the writing task for long periods. The whole effort will likely be a work in progress, and continuous refinements in the written material will occur once the writing process has begun.

LITERATURE REVIEW CHECKLIST

In contrast to review papers, the LR of a dissertation/thesis should not be a standalone piece or work. Instead, it should present the student as a scholar and should maintain the interest of the audience in how that dissertation/thesis will provide solutions for the current gaps in a particular field.

A checklist for evaluating an LR is convenient for students’ continuous academic development and research transparency: it clearly states the desired achievements for the LR of a dissertation/thesis. Here, we present an LR checklist developed from an LR scoring rubric ( 11 ). For a critical analysis of an LR, we maintain the five categories but offer twelve criteria that are not scaled ( Figure 3 ). The criteria all have the same importance and are not mutually exclusive.

An external file that holds a picture, illustration, etc.
Object name is cln-74-e1403-g003.jpg

First category: Coverage

1. justified criteria exist for the inclusion and exclusion of literature in the review.

This criterion builds on the main topic and areas covered by the LR ( 18 ). While experts may be confident in retrieving and selecting literature, postgraduate students must convince their audience about the adequacy of their search strategy and their reasons for intentionally selecting what material to cover ( 11 ). References from different fields of knowledge provide distinct perspective, but narrowing the scope of coverage may be important in areas with a large body of existing knowledge.

Second category: Synthesis

2. a critical examination of the state of the field exists.

A critical examination is an assessment of distinct aspects in the field ( 1 ) along with a constructive argument. It is not a negative critique but an expression of the student’s understanding of how other scholars have added to the topic ( 1 ), and the student should analyze and contextualize contradictory statements. A writer’s personal bias (beliefs or political involvement) have been shown to influence the structure and writing of a document; therefore, the cultural and paradigmatic background guide how the theories are revised and presented ( 13 ). However, an honest judgment is important when considering different perspectives.

3. The topic or problem is clearly placed in the context of the broader scholarly literature

The broader scholarly literature should be related to the chosen main topic for the LR ( how to develop the literature review section). The LR can cover the literature from one or more disciplines, depending on its scope, but it should always offer a new perspective. In addition, students should be careful in citing and referencing previous publications. As a rule, original studies and primary references should generally be included. Systematic and narrative reviews present summarized data, and it may be important to cite them, particularly for issues that should be understood but do not require a detailed description. Similarly, quotations highlight the exact statement from another publication. However, excessive referencing may disclose lower levels of analysis and synthesis by the student.

4. The LR is critically placed in the historical context of the field

Situating the LR in its historical context shows the level of comfort of the student in addressing a particular topic. Instead of only presenting statements and theories in a temporal approach, which occasionally follows a linear timeline, the LR should authentically characterize the student’s academic work in the state-of-art techniques in their particular field of knowledge. Thus, the LR should reinforce why the dissertation/thesis represents original work in the chosen research field.

5. Ambiguities in definitions are considered and resolved

Distinct theories on the same topic may exist in different disciplines, and one discipline may consider multiple concepts to explain one topic. These misunderstandings should be addressed and contemplated. The LR should not synthesize all theories or concepts at the same time. Although this approach might demonstrate in-depth reading on a particular topic, it can reveal a student’s inability to comprehend and synthesize his/her research problem.

6. Important variables and phenomena relevant to the topic are articulated

The LR is a unique opportunity to articulate ideas and arguments and to purpose new relationships between them ( 10 , 11 ). More importantly, a sound LR will outline to the audience how these important variables and phenomena will be addressed in the current academic work. Indeed, the LR should build a bidirectional link with the remaining sections and ground the connections between all of the sections ( Figure 1 ).

7. A synthesized new perspective on the literature has been established

The LR is a ‘creative inquiry’ ( 13 ) in which the student elaborates his/her own discourse, builds on previous knowledge in the field, and describes his/her own perspective while interpreting others’ work ( 13 , 17 ). Thus, students should articulate the current knowledge, not accept the results at face value ( 11 , 13 , 17 ), and improve their own cognitive abilities ( 12 ).

Third category: Methodology

8. the main methodologies and research techniques that have been used in the field are identified and their advantages and disadvantages are discussed.

The LR is expected to distinguish the research that has been completed from investigations that remain to be performed, address the benefits and limitations of the main methods applied to date, and consider the strategies for addressing the expected limitations described above. While placing his/her research within the methodological context of a particular topic, the LR will justify the methodology of the study and substantiate the student’s interpretations.

9. Ideas and theories in the field are related to research methodologies

The audience expects the writer to analyze and synthesize methodological approaches in the field. The findings should be explained according to the strengths and limitations of previous research methods, and students must avoid interpretations that are not supported by the analyzed literature. This criterion translates to the student’s comprehension of the applicability and types of answers provided by different research methodologies, even those using a quantitative or qualitative research approach.

Fourth category: Significance

10. the scholarly significance of the research problem is rationalized.

The LR is an introductory section of a dissertation/thesis and will present the postgraduate student as a scholar in a particular field ( 11 ). Therefore, the LR should discuss how the research problem is currently addressed in the discipline being investigated or in different disciplines, depending on the scope of the LR. The LR explains the academic paradigms in the topic of interest ( 13 ) and methods to advance the field from these starting points. However, an excess number of personal citations—whether referencing the student’s research or studies by his/her research team—may reflect a narrow literature search and a lack of comprehensive synthesis of ideas and arguments.

11. The practical significance of the research problem is rationalized

The practical significance indicates a student’s comprehensive understanding of research terminology (e.g., risk versus associated factor), methodology (e.g., efficacy versus effectiveness) and plausible interpretations in the context of the field. Notably, the academic argument about a topic may not always reflect the debate in real life terms. For example, using a quantitative approach in epidemiology, statistically significant differences between groups do not explain all of the factors involved in a particular problem ( 21 ). Therefore, excessive faith in p -values may reflect lower levels of critical evaluation of the context and implications of a research problem by the student.

Fifth category: Rhetoric

12. the lr was written with a coherent, clear structure that supported the review.

This category strictly relates to the language domain: the text should be coherent and presented in a logical sequence, regardless of which organizational ( 18 ) approach is chosen. The beginning of each section/subsection should state what themes will be addressed, paragraphs should be carefully linked to each other ( 10 ), and the first sentence of each paragraph should generally summarize the content. Additionally, the student’s statements are clear, sound, and linked to other scholars’ works, and precise and concise language that follows standardized writing conventions (e.g., in terms of active/passive voice and verb tenses) is used. Attention to grammar, such as orthography and punctuation, indicates prudence and supports a robust dissertation/thesis. Ultimately, all of these strategies provide fluency and consistency for the text.

Although the scoring rubric was initially proposed for postgraduate programs in education research, we are convinced that this checklist is a valuable tool for all academic areas. It enables the monitoring of students’ learning curves and a concentrated effort on any criteria that are not yet achieved. For institutions, the checklist is a guide to support supervisors’ feedback, improve students’ writing skills, and highlight the learning goals of each program. These criteria do not form a linear sequence, but ideally, all twelve achievements should be perceived in the LR.

CONCLUSIONS

A single correct method to classify, evaluate and guide the elaboration of an LR has not been established. In this essay, we have suggested directions for planning, structuring and critically evaluating an LR. The planning of the scope of an LR and approaches to complete it is a valuable effort, and the five steps represent a rational starting point. An institutional environment devoted to active learning will support students in continuously reflecting on LRs, which will form a dialogue between the writer and the current literature in a particular field ( 13 ).

The completion of an LR is a challenging and necessary process for understanding one’s own field of expertise. Knowledge is always transitory, but our responsibility as scholars is to provide a critical contribution to our field, allowing others to think through our work. Good researchers are grounded in sophisticated LRs, which reveal a writer’s training and long-lasting academic skills. We recommend using the LR checklist as a tool for strengthening the skills necessary for critical academic writing.

A literature review is a review and synthesis of existing research on a topic or research question. A literature review is meant to analyze the scholarly literature, make connections across writings and identify strengths, weaknesses, trends, and missing conversations. A literature review should address different aspects of a topic as it relates to your research question. A literature review goes beyond a description or summary of the literature you have read.

why is literature review important in research proposal

Organize the literature review into sections that present themes or identify trends, including relevant theory. You are not trying to list all the material published, but to synthesize and evaluate it according to the guiding concept of your thesis or research question.  

What is a literature review?

A literature review is an account of what has been published on a topic by accredited scholars and researchers. Occasionally you will be asked to write one as a separate assignment, but more often it is part of the introduction to an essay, research report, or thesis. In writing the literature review, your purpose is to convey to your reader what knowledge and ideas have been established on a topic, and what their strengths and weaknesses are. As a piece of writing, the literature review must be defined by a guiding concept (e.g., your research objective, the problem or issue you are discussing, or your argumentative thesis). It is not just a descriptive list of the material available, or a set of summaries

A literature review must do these things:

  • be organized around and related directly to the thesis or research question you are developing
  • synthesize results into a summary of what is and is not known
  • identify areas of controversy in the literature
  • formulate questions that need further research

Ask yourself questions like these:

  • What is the specific thesis, problem, or research question that my literature review helps to define?
  • What type of literature review am I conducting? Am I looking at issues of theory? methodology? policy? quantitative research (e.g. on the effectiveness of a new procedure)? qualitative research (e.g., studies of loneliness among migrant workers)?
  • What is the scope of my literature review? What types of publications am I using (e.g., journals, books, government documents, popular media)? What discipline am I working in (e.g., nursing psychology, sociology, medicine)?
  • How good was my information seeking? Has my search been wide enough to ensure I've found all the relevant material? Has it been narrow enough to exclude irrelevant material? Is the number of sources I've used appropriate for the length of my paper?
  • Have I critically analyzed the literature I use? Do I follow through a set of concepts and questions, comparing items to each other in the ways they deal with them? Instead of just listing and summarizing items, do I assess them, discussing strengths and weaknesses?
  • Have I cited and discussed studies contrary to my perspective?
  • Will the reader find my literature review relevant, appropriate, and useful?

Ask yourself questions like these about each book or article you include:

  • Has the author formulated a problem/issue?
  • Is it clearly defined? Is its significance (scope, severity, relevance) clearly established?
  • Could the problem have been approached more effectively from another perspective?
  • What is the author's research orientation (e.g., interpretive, critical science, combination)?
  • What is the author's theoretical framework (e.g., psychological, developmental, feminist)?
  • What is the relationship between the theoretical and research perspectives?
  • Has the author evaluated the literature relevant to the problem/issue? Does the author include literature taking positions she or he does not agree with?
  • In a research study, how good are the basic components of the study design (e.g., population, intervention, outcome)? How accurate and valid are the measurements? Is the analysis of the data accurate and relevant to the research question? Are the conclusions validly based upon the data and analysis?
  • In material written for a popular readership, does the author use appeals to emotion, one-sided examples, or rhetorically-charged language and tone? Is there an objective basis to the reasoning, or is the author merely "proving" what he or she already believes?
  • How does the author structure the argument? Can you "deconstruct" the flow of the argument to see whether or where it breaks down logically (e.g., in establishing cause-effect relationships)?
  • In what ways does this book or article contribute to our understanding of the problem under study, and in what ways is it useful for practice? What are the strengths and limitations?
  • How does this book or article relate to the specific thesis or question I am developing?

How to Prepare a Research Proposal and Literature Review

All HDR candidates are required to prepare a research proposal and literature review for their first Research Progress Review. If you are a PhD candidate, this will be your Confirmation Review. 

Your research proposal and literature review should be a comprehensive outline of your research topic and show how you will make an original contribution to knowledge in your field. Your Review panel will use your research proposal and literature review to assess the viability of your research project, and to provide you with valuable feedback on your topic, methodology, research design, timeline and milestones. 

UNSW Academic Skills provides a detailed description of how to develop and structure your research proposal. 

Your Faculty and/or School may have particular requirements, and you should contact your Postgraduate Coordinator or your supervisor if you’re unsure of what is required.

5 Reasons the Literature Review Is Crucial to Your Paper

5 Reasons the Literature Review Is Crucial to Your Paper

3-minute read

  • 8th November 2016

People often treat writing the literature review in an academic paper as a formality. Usually, this means simply listing various studies vaguely related to their work and leaving it at that.

But this overlooks how important the literature review is to a well-written experimental report or research paper. As such, we thought we’d take a moment to go over what a literature review should do and why you should give it the attention it deserves.

What Is a Literature Review?

Common in the social and physical sciences, but also sometimes required in the humanities, a literature review is a summary of past research in your subject area.

Sometimes this is a standalone investigation of how an idea or field of inquiry has developed over time. However, more usually it’s the part of an academic paper, thesis or dissertation that sets out the background against which a study takes place.

Like a timeline, but a bit more wordy.

There are several reasons why we do this.

Reason #1: To Demonstrate Understanding

In a college paper, you can use a literature review to demonstrate your understanding of the subject matter. This means identifying, summarizing and critically assessing past research that is relevant to your own work.

Reason #2: To Justify Your Research

The literature review also plays a big role in justifying your study and setting your research question . This is because examining past research allows you to identify gaps in the literature, which you can then attempt to fill or address with your own work.

Reason #3: Setting a Theoretical Framework

It can help to think of the literature review as the foundations for your study, since the rest of your work will build upon the ideas and existing research you discuss therein.

A crucial part of this is formulating a theoretical framework , which comprises the concepts and theories that your work is based upon and against which its success will be judged.

A framework made of theories. No, wait. This one's metal.

Reason #4: Developing a Methodology

Conducting a literature review before beginning research also lets you see how similar studies have been conducted in the past. By examining the strengths and weaknesses of existing research, you can thus make sure you adopt the most appropriate methods, data sources and analytical techniques for your own work.

Reason #5: To Support Your Own Findings

The significance of any results you achieve will depend to some extent on how they compare to those reported in the existing literature. When you come to write up your findings, your literature review will therefore provide a crucial point of reference.

If your results replicate past research, for instance, you can say that your work supports existing theories. If your results are different, though, you’ll need to discuss why and whether the difference is important.

"Contrary to previous research, this study suggests that pigs can actually fly. This may have major implications for the production of bacon."

Tips on Preparing a Research Proposal

Common mistakes to avoid.

  • Failure to be concise.  A research proposal must be focused and not be "all over the map" or diverge into  on unrelated tangents without a clear sense of purpose.
  • Failure to cite landmark works in your literature review.  Proposals should be grounded in foundational research that lays a foundation for understanding the development and scope of the issue.
  • Failure to delimit the contextual boundaries of your research  [e.g., time, place, people, etc.]. As with any research paper, your proposed study must inform the reader how and in what ways the study will examine the problem.
  • Failure to develop a coherent and persuasive argument for the proposed research . This is critical. In many workplace settings, the research proposal is intended to argue for why a study should be funded.
  • Sloppy or imprecise writing, or poor grammar.  Although a research proposal does not represent a completed research study, there is still an expectation that it is well-written and follows the style and rules of good academic writing.
  • Too much detail on minor issues, but not enough detail on major issues.  Your proposal should focus on only a few key research questions in order to support the argument that the research needs to be conducted. Minor issues, even if valid, can be mentioned but they should not dominate the overall narrative.

Research Proposals

why is literature review important in research proposal

What is a Research Proposal

A research proposal is simply a structured, formal document that explains  what  you plan to research (i.e. your research topic),  why  it’s worth r esearching (i.e. your justification), and  how  you plan to investigate it (i.e. your practical approach). 

The purpose of the research proposal (it’s job, so to speak) is to  convince  your research supervisor, committee or university that your research is  suitable  (for the requirements of the degree program) and  manageable  (given the time and resource constraints you will face). 

The most important word here is “ convince ” – in other words, your research proposal needs to  sell  your research idea (to whoever is going to approve it). If it doesn’t convince them (of its suitability and manageability), you’ll need to revise and resubmit. This will cost you valuable time, which will either delay the start of your research or eat into its time allowance (which is bad news). 

Research proposals generally follow the same format as a research paper, with an introduction, a literature review, a discussion of research methodology and goals, and a conclusion.

From: Wong, Paul T. P.  How to Write a Research Proposal . International Network on Personal Meaning. Trinity Western University

Components of a Research Proposal

Introduction.

The first part of your proposal is the initial pitch for your project, so make sure it succinctly explains what you want to do and why. It should:

  • Introduce the topic
  • Give background and context
  • Outline your  t problem statement and research question(s)

Some important questions to guide your introduction include:

  • Who has an interest in the topic (e.g. scientists, practitioners, policymakers, particular members of society)?
  • How much is already known about the problem?
  • What is missing from current knowledge?
  • What new insights will your research contribute?
  • Why is this research worth doing?

If your proposal is very long, you might include separate sections with more detailed information on the background and context, problem statement, aims and objectives, and importance of the research.

Literature review

It’s important to show that you’re familiar with the most important research on your topic. A strong  literature review  convinces the reader that your project has a solid foundation in existing knowledge or theory. It also shows that you’re not simply repeating what other people have already done or said.

In this section, aim to demonstrate exactly how your project will contribute to conversations in the field.

  • Compare and contrast: what are the main theories, methods, debates and controversies?
  • Be critical: what are the strengths and weaknesses of different approaches?
  • Show how your research fits in: how will you build on, challenge, or synthesize the work of others?

The literature review serves several important functions:

  • Ensures that you are not "reinventing the wheel".
  • Gives credits to those who have laid the groundwork for your research.
  • Demonstrates your knowledge of the research problem.
  • Demonstrates your understanding of the theoretical and research issues related to your research question.
  • Shows your ability to critically evaluate relevant literature information.
  • Indicates your ability to integrate and synthesize the existing literature.
  • Provides new theoretical insights or develops a new model as the conceptual framework for your research.
  • Convinces your reader that your proposed research will make a significant and substantial contribution to the literature (i.e., resolving an important theoretical issue or filling a major gap in the literature).

The purpose of the discussion is to interpret and describe the significance of your findings in light of what was already known about the research problem being investigated, and to explain any new understanding or fresh insights about the problem after you've taken the findings into consideration. The discussion will always connect to the introduction by way of the research questions or hypotheses you posed and the literature you reviewed, but it does not simply repeat or rearrange the introduction; the discussion should always explain how your study has moved the reader's understanding of the research problem forward from where you left them at the end of the introduction.

This section is often considered the most important part of a research paper  because it most effectively demonstrates your ability as a researcher to think critically about an issue, to develop creative solutions to problems based on the findings, and to formulate a deeper, more profound understanding of the research problem you are studying.

The discussion section is where you explore the underlying meaning of your research , its possible implications in other areas of study, and the possible improvements that can be made in order to further develop the concerns of your research.

This is the section where you need to present the importance of your study  and how it may be able to contribute to and/or fill existing gaps in the field. If appropriate, the discussion section is also where you state how the findings from your study revealed new gaps in the literature that had not been previously exposed or adequately described.

This part of the paper is not strictly governed by objective reporting of information  but, rather, it is where you can engage in creative thinking about issues through evidence-based interpretation of findings. This is where you infuse your results with meaning.

Kretchmer, Paul.  Fourteen Steps to Writing to Writing an Effective Discussion Section . San Francisco Edit, 2003-2008.

The conclusion is intended to help the reader understand why your research should matter to them after they have finished reading the paper. A conclusion is not merely a summary of your points or a re-statement of your research problem but a synthesis of key points. For most essays, one well-developed paragraph is sufficient for a conclusion, although in some cases, a two-or-three paragraph conclusion may be required.

A well-written conclusion provides you with several important opportunities to demonstrate your overall understanding of the research problem to the reader. These include:

  • Presenting the last word on the issues you raised in your paper . Just as the introduction gives a first impression to your reader, the conclusion offers a chance to leave a lasting impression. Do this, for example, by highlighting key points in your analysis or findings.
  • Summarizing your thoughts and conveying the larger implications of your study . The conclusion is an opportunity to succinctly answer the "so what?" question by placing the study within the context of past research about the topic you've investigated.
  • Demonstrating the importance of your ideas . Don't be shy. The conclusion offers you a chance to elaborate on the significance of your findings.
  • Introducing possible new or expanded ways of thinking about the research problem . This does not refer to introducing new information [which should be avoided], but to offer new insight and creative approaches for framing/contextualizing the research problem based on the results of your study.

Importance of Literature Review

Profile image of Bob  mweetwa

research proposal as a problem to investigate, it usually has to be fairly narrow and focused, and because of this it can be difficult to appreciate how one's research subject is connected to other related areas. Therefore, the overall purpose of a literature review is to demonstrate this, and to help the reader to understand how your study fits into a broader context. This paper seeks to examine this topic of literature review, its significance and role in research proposal and report. It will start by explaining in detail what literature is; by citation of different scholars and its constituent components, such as the theoretical framework. Thereafter, it will look at the importance of literature review and its role in research proposals and reports. Finally, a conclusion will be written based on this topic. A Literature Review is a critical review of existing knowledge on areas such as theories, critiques, methodologies, research findings, assessment and evaluations on a particular topic. A literature review involves a critical evaluation identifying similarities and differences between existing literatures and the work being undertaken. It reviews what have already been done in the context of a topic. Therefore, on the basis of the existing knowledge, people can build up innovative idea and concept for further research purpose (Cooper, 1998). In doing empirical literature review is reading reports of other relevant studies conducted by different researchers. In doing so, a researcher gets knowledge and experiences that were established by other researchers when conducting their studies. While Conceptual framework is a set of coherent ideas or concepts organised in a manner that makes them easy to communicate to others. It represents less formal structure and used for specific concepts and propositions derived from empirical observation and intuition (ibid). According Aveyard, H. (2010) Theoretical framework is a theoretical perspective. It can be simply a theory, but can also be more general a basic approach to understanding something. Typically, a theoretical framework consists of concepts, together with their definitions, and existing framework must demonstrate an understanding of theories, and existing framework demonstrate an understanding of theories and concepts that are relevant to the topic of your research proposal and that will relate it to the broader fields of knowledge in the class you are taking.

This article critically discusses, the relationship between conceptual framework and theoretical framework drawing on their differences and similarities. The article has made it very clear that whereas the theoretical framework is drawn from the existing theoretical literature that you review about your research topic, a conceptual framework is a much broader concept that encompasses practically all aspects of your research. The latter refers to the entire conceptualisation of your research project. It is the big picture, or vision, comprising the totality of research. Methodologically, the paper used systematic and experiential literature review to draw supporting scholarly literature by authorities in the field and made inferences, sound reasonings and logical deductions from these authorities. The primary aim of this paper is to help researchers and students to understand the convergence and the divergence of theoretical and conceptual frameworks in order to appropriately be applied in research and academic writing discourses. Understanding the conceptual framework affects research in many ways. For instance, it assists the researcher in identifying and constructing his/her worldview on the phenomenon to be investigated. Also, it is the simplest way through which a researcher presents his/her asserted remedies to the milieu he/she has created. In addition, this accentuates the reasons why a research topic is worth studying, the assumptions of a researcher, the scholars he/she agrees with and disagrees with and how he/she conceptually grounds his/her approach. Paying attention, to the theoretical framework and its impact on research, it can be mentioned that theoretical framework provides a structure for what to look for in the data, for how you think of how what you see in the data fits together, and helps you to discuss your findings more clearly, in light of what existing theories say. It helps the researcher to make connections between the abstract and concrete elements observed in the data. In conclusion, both theoretical framework and conceptual framework are good variables which are used to inform a study to arrive at logical findings and conclusions. It is therefore recommended by researchers that; a good theoretical framework should be capable of informing the concepts in a research work.

ABSTRACT A number of researchers either in scientific, social or academic researchers have found it difficult to differentiate between the theoretical and conceptual framework and their importance. This is a simple overview of the basic differences and some similarities between the theoretical and conceptual framework that is aimed at helping the learners and other researchers get a fast grasp of what can help them use the two effectively in their studies. A summary has been provided at the last part of the document that can aid one get the required information in his or her research.

Abstract This essay starts with a discussion of the literature review, theoretical framework, and conceptual framework as components of a manuscript. This discussion includes similarities and distinctions among these components and their relation to other sections of a manuscript such as the problem statement, discussion, and implications. The essay concludes with an overview of the literature review, theoretical framework, and conceptual framework as separate types of manuscripts.

The impetus of this paper is the irreplaceable role yet confusing use of the term " conceptual framework " in research literature. Even though, there is a consensus among scholars of various field of study that conceptual framework is essential element of research endeavors, yet it is used interchangeably with theoretical framework, that create confusion. As a PhD student on the pre-proposal work, this makes me more anxious. Then my intent is to explore its conceptual meaning and purposes by bringing together similar meanings from different scholars with a view to shed some light on its understanding and its use in research. Hence, in attempting to address this, the following key terms; Concept, conceptual framework research design and theoretical framework are defined briefly as to help decipher the conceptual ties among them and illuminate the conceptual meaning and purpose of conceptual framework. The schematic representation of conceptual framework is developed based on the conceptual meaning provided by scholars. In doing this it is attempted to show conceptual meaning of conceptual framework in relation to research design, paradigms and philosophical assumptions that delineate it from theoretical framework. Conceptual framework serves essential role in inductive research design, while theoretical framework serves similar role in deductive research design.

This is an opinion piece on the subject of whether or not 'theoretical' and 'conceptual' frameworks are conceptual synonyms, or they refer to different constructs. Although, generally, a lot of liter ature uses these two terms interchangeably – suggesting that they are conceptually equivalent, the researcher argues that these are two different constructs – both by definition and as actualised during the research process. Thus, in this paper, the researcher starts by developing his argument by examining the role of theory in research, and then draws a distinction between areas of research that typically follow deductive versus inductive approaches, with regard to both the review of literature and data collection. The researcher then subsequently argues that whereas a deductive approach to literature review typically makes use of theories and theoretical frameworks, the induct ive approach tends to lead to the development of a conceptual framework – which may take the form of a (conceptua l) model. Examples depicting this distinction are advanced.

Conceptual framework is the foundation of scientific research, and it is formed from previous knowledge about the researched phenomenon. It is an integral part of theoretical framework, made with the aim to include key terms, presented within the bibliography, and create a suitable platform to develop the research correctly. More often with students preparing their final papers, and not so rarely with established researchers, the problem arises when it comes to conceptualizing research. A common unknown is how to divide conceptual from theoretical framework, and what conceptual framework of scientific research actually is. The aim of this paper is to clarify conceptualization of scientific research, and, by clarifying it, to point out the significance of differentiation between conceptual and theoretical framework, going on to give basic guidelines on how to form one, and therefore ease the understanding of it and application in scientific research.

Conducting educational research involves various stages, with an interdependence and inter-relationship which can be both iterative and progressive in nature. One of these stages is the review of literature sources related to the focus of the research. Reviewing related literature involves tracing, examining, critiquing, evaluating and eventually recommending various forms of contents to the intents of the research based on the content’s typicality, relevance, correctness and appropriateness to what the research intends to achieve. The main variables as stated in the title of the research, the research questions, the research objectives and the hypotheses, dictates the literature sources to review. Reviewing literature focuses on the existing related topics that bear relevance to the title of the research and through which reviewing, appropriate theories can be picked up as the review of related topics and phrases goes on. As soon as the related topics are reviewed and main points noted, the reviewing process proceeds to review the theories underpinning the study. Some of these theories would have been established while reviewing the related topics and can now gain momentum, while other theories can now be generated considering the title, research questions, research objectives and findings of the topics reviewed and discussed earlier. Reviewing related topics generates main points of arguments, solutions, gaps and propositions. Similarly, reviewing theories does produce the same set of corresponding or contrasting agreements, gaps and propositions. Despite reviewing different sources of literature, it is the same research at hand, with same objectives and same methodological layout. Hence, a need to shape a strategic, literature direction for the research by consolidating the key findings of the different sources reviewed, in view of the intents of the research. The process of consolidating the multiplicity of key literature findings relevant to the research into a whole single unit, with one standpoint revealing the strategic literature direction for the research, is called constructing a conceptual framework. The end product of this construction is the conceptual framework, which is the informed and consolidated results presented narratively or schematically, revealing the strategic position of the study in relation to what exists in literature.

Many students, both in the undergraduate and graduate levels, have difficulty discriminating the theoretical from the conceptual framework. This requires a good understanding of both frameworks in order to conduct a good investigation. This article explains the two concepts in easily understandable language. Read on to find out. Many graduating college students and even graduate students have difficulty coming up with the conceptual framework and the theoretical framework of their thesis, a required section in thesis writing that serves as the students' map on their first venture into research. The conceptual framework is almost always confused with the theoretical framework of the study. What is the difference between the conceptual and the theoretical framework? A conceptual framework is the researcher's idea on how the research problem will have to be explored. This is founded on the theoretical framework, which lies on a much broader scale of resolution. The theoretical framework dwells on time tested theories that embody the findings of numerous investigations on how phenomena occur. The theoretical framework provides a general representation of relationships between things in a given phenomenon. The conceptual framework, on the other hand, embodies the specific direction by which the research will have to be undertaken. Statistically speaking, the conceptual framework describes the relationship between specific variables identified in the study. It also outlines the input, process and output of the whole investigation. The conceptual framework is also called the research paradigm. Examples of the Theoretical and the Conceptual Framework The difference between theoretical framework and conceptual framework can be further clarified by the following examples on both concepts: Theoretical Framework: Stimulus elicits response. Conceptual Framework: New teaching method improves students' academic performance. Notice in the illustrative example that the theoretical framework basically differs from the conceptual framework in terms of scope. The theoretical framework describes a broader relationship between things. When stimulus is applied, response is expected. The conceptual framework is much more specific in defining this relationship. The conceptual framework specifies the variables that will have to be explored in the investigation. In this example, the variable " teaching method " represents stimulus while

Importance of Literature Review in Research Proposals

Table of Contents

A literature review is an integral part of any research proposal. What should a sample literature review for research proposal contain? You’ll find answers to this question in this article.

But first, let’s understand the importance of a literature review in a research proposal.

What Is the Importance of Literature Review in a Research Proposal

A literature review helps to introduce the topic being addressed and provides a detailed overview of the existing knowledge on that subject. Also, it points out areas where there may be gaps in the current understanding or where more research is needed.

Furthermore, reading other authors’ works can provide insight into how they tackled a similar question or issue. It may even help the student refine their research question.

What Should a Good Sample Literature Review for Research Proposal Include?

A good sample literature review for research proposal should cover all essential elements. We explain these key elements below.

Include the Most Relevant Works

Relevant works are essential to your literature review. It is one of the most important things you must pay attention to. You can’t show that you’ve thoroughly researched the topic without including the most pertinent works.

Therefore, you must select the most relevant works according to their relevance to the question being addressed.

State How They Support Your Research

It’s crucial to clearly state how these works support your research. By introducing this body of work, you are providing the context which allows others to understand why you have chosen a particular method.

It is also a way of giving them an idea of the results you will achieve and the potential impact of your proposed study. It may also help to move new scientific research forward.

Choose up-to-Date Sources

To get the best out of a literature review, choose sources that are up-to-date and provide a variety of perspectives.

Your sources must be up-to-date to avoid instances where your thesis is based on outdated research. A literature review should include essential information from multiple sources, including articles, books, journals, websites, and databases.

How to Write Your Literature Review

Below are tips to help you write a good literature review.

Create an Outline

Don’t give in to the temptation to simply start writing right away. You may get confused. By creating an outline, you’ll be able to piece up every bit of information you’ve gathered logically. Without an outline, you may end up missing out on key details or presenting illogical arguments.

Draft Your Literature Review

eyeglasses with gray frames on the top of notebook

With your outline, you can now draft your literature review. Remember that your first draft doesn’t have to be perfect. Trying to write an excellent literature review the first time isn’t always possible.

Don’t put too much pressure on yourself. Instead, focus on putting something down first. After your first draft, you may take time off to cool off. Come back to it after a day or two to perfect the rough edges.

Finally, you should proofread your final draft. Check to make sure your grammar and punctuation are on point. Don’t forget your citations as well. Make sure all sources are appropriately cited.

Final Thoughts

A literature review is an essential part of a research proposal. It allows you to survey and analyze existing information on a given topic from multiple sources , including articles, books, journals, websites, and databases. It helps to establish the relevancy and validity of your research proposal.
