What is LR?
? The format of a review of literature may vary from discipline to discipline and from assignment to assignment.
? A review may be a self-contained unit -- an end in itself -- or a preface to and rationale for engaging in primary research. A review is a required part of grant and research proposals and often a chapter in theses and dissertations.
? It might give a new interpretation of old material or combine new with old interpretations.
? Or it might trace the intellectual progression of the field, including major debates.

literature review 范本
literature review 范本A literature review is a comprehensive and critical evaluation of existing scholarship on a particular topic. It aims to identify and synthesize relevant research, provide a summary of current knowledge on the topic, and identify gaps or areas for further study. Below is a sample literature review on the topic of mental health in adolescence:Title: Mental Health in Adolescence: A Comprehensive Literature ReviewIntroduction:Adolescence is a critical period in a person's life, characterized by significant physical, psychological, and social changes. Mental health issues can significantly impact the well-being and future trajectories of adolescents. Therefore, understanding the current research on mental health in this population is crucial to inform policy decisions, intervention strategies, and future research. This literature review aims to synthesize the existing knowledge on mental health in adolescence, identify the factors contributing to mental health issues, and explore potential interventions to improve the well-being of adolescents.Methodology:This review utilizes a systematic approach to identify relevant scholarly articles and research papers. Databases such as PubMed, PsycINFO, and Google Scholar were searched using specific keywords, including "adolescent mental health," "mental health interventions," "risk factors," and "protective factors." The search was limited to articles published in the last ten years to ensure theinclusion of recent research. The initial search yielded 500 articles, which were screened based on their relevance to the topic. After the screening process, 50 articles were included in the final review. Findings:Mental health issues in adolescence are multifaceted and influenced by various individual, familial, and social factors. The most prevalent mental health disorders among adolescents include anxiety, depression, and substance abuse disorders. Risk factors such as familial history of mental illness, adverse childhood experiences, peer pressure, and academic stress significantly contribute to the development of mental health issues in this population.Protective factors, on the other hand, act as buffers and promote resilience in adolescents. These include social support, strong family relationships, positive school environments, and access to mental health services. Interventions targeted at enhancing protective factors and reducing risk factors have shown promising results in improving the mental well-being of adolescents. Cognitive-behavioral therapy, mindfulness-based interventions, and peer support programs have emerged as effective interventions for managing mental health disorders in this population.Despite the growing body of research on adolescent mental health, several gaps exist in the current literature. Limited research is available on the mental health concerns of specific subgroups, such as LGBTQ+ adolescents and those from marginalized communities. Furthermore, more research is needed to understand the long-term impacts of mental health interventions and the role of technologyin mental health promotion and prevention.Conclusion:This literature review provides a comprehensive overview of the current research on mental health in adolescence. It highlights the importance of addressing mental health issues in this population, identifies the factors contributing to these issues, and explores potential avenues for intervention. Future research should focus on filling the existing gaps in knowledge, developing culturally sensitive interventions, and utilizing technology to improve mental health outcomes among adolescents. Ultimately, a holistic approach incorporating social, familial, and individual factors is crucial for promoting the mental well-being of adolescents.。

literature review的introduction
literature review的introductionIntroductionLiterature review is an essential component of academic research papers and dissertations. It involves systematically analyzing previous studies, theories, and scholarly articles relevant to the topic under investigation. By reviewing existing literature, researchers gain a comprehensive understanding of the existing knowledge, identify research gaps, and develop a theoretical framework for their own study. This introduction will discuss the importance of literature review, its purpose, and how it contributes to the overall research process.Importance of Literature ReviewLiterature review plays a crucial role in academic research as it helps establish the context and theoretical foundation for a study. It allows researchers to build upon prior work and contributes to the progression of knowledge in their specific field. By examining existing literature, researchers can identify the key theories, concepts, methodologies, and findings that are relevant to their research question. This process enables them to position their study within the existing scholarly discussion and contribute new insights to the body of knowledge.Purpose of Literature ReviewThe purpose of conducting a literature review goes beyond summarizing existing studies. It involves a critical analysis of the literature to identify the strengths and weaknesses of past research.By evaluating the credibility, relevance, and limitations of previous studies, researchers can identify gaps or unresolved issues in the literature. These research gaps provide the rationale for the current study, highlighting the need for further investigation. Therefore, literature review helps researchers identify the research questions and objectives that will guide their own study.Contribution to the Research ProcessLiterature review serves as a foundation for the research process by informing the research design, methodology, and data analysis. By synthesizing and interpreting the findings from past studies, researchers can identify the most appropriate research methods and data collection techniques for their own study. Literature review also helps researchers develop a conceptual framework or theoretical model for their study, guiding the formulation of hypotheses and research questions. Furthermore, by identifying gaps in the literature, researchers can design research studies that address the limitations of previous work and contribute new knowledge to the field.ConclusionThe introduction of a literature review provides an overview of its importance, purpose, and contribution to the research process. It highlights the significance of literature review in establishing the context for a study, identifying research gaps, and developing a theoretical framework. By conducting a thorough literature review, researchers can position their study within the existing scholarly discussion, establish the credibility of their research, and contributenew insights to the field. Overall, literature review forms an integral part of the research process and is crucial for generating high-quality and impactful research.。

II. The purposes of literature review And Its ComponentsA. The PurposesOn the one hand, it helps you broaden the view and perspective of the topic for your graduation thesis.On the other hand, it helps you narrow down the topic and arrive at a focusedresearch question.B. Its ComponentsThere are six parts in a complete Literature Review.标题与作者(title and author)摘要与关键词(abstract and key words)引言(introduction)述评(review)结论(conclusion)参考文献(references)III. Classification of Source MaterialsHow can we locate the materials relevant to our topics betterand faster? Basically, all these source materials may be classified into four majors of sources.A: Background sources:Basic information which can usually be found in dictionaries andencyclopedia complied by major scholars or founders of the field. Three very good and commonly recommenced encyclopedias are encyclopedias ABC, namely, Encyclopedia Americana, Encyclopedia Britannica, and Collier’s Encyclopedia. There are also reference works more specialized, such as The Encyclopedia of Language and Linguistics for linguistics and TEFL studies. Moreover, you may also find Encyclopedia on the web.B: Primary sourcesThose providing direct evidence, such as works of scholars of the field,biographies or autobiographies, memoirs, speeches, lectures, diaries, collection of letters, interviews, case studies, approaches, etc. Primary sources come in various shapes and sizes, and often you have to do a little bit of research about the source to make sure you have correctly identified it. When a first search yields too few results, try searching by broader topic; when a search yields toomany results, refine your search by narrowing down your search.C: Secondary sourcesThose providing indirect evidence, such as research articles or papers, bookreviews, assays, journal articles by experts in a given field, studies on authors orwriters and their works, etc. Secondary sources will informmost of your writingin college. You will often be asked to research your topic using primary sources,but secondary sources will tell you which primary sources you should use andwill help you interpret those primary sources. T o use theme well, however, youneed to think critically them. There are two parts of a source that you need toanalyze: the text itself and the argument within the text.D: Web sourcesThe sources or information from websites. Web serves as an excellentresource for your materials. However, you need to select and evaluate Websources with special care for very often Web sources lack quality control. Youmay start with search engines, such as Google, Yahoo, Ask, Excit e, etc. It’s agood idea to try more than one search engine, since each locates sources in itsown way. When using websites for information, be sure to take care for theauthorship and sponsorship. If they are both unclear, be critical when you useinformation. The currency of website information should also be taken intoaccount. Don’t use too out information dated for your purpose.IV. Major strategies of Selecting Materials for literaturereviewA. Choosing primary sources rather than secondary sourcesIf you have two sources, one of them summarizing or explaining a work andthe other the work itself, choose the work itself. Never attempt to write a paperon a topic without reading the original source.B. Choosing sources that give a variety of viewpoints on your thesisRemember that good argument essays take into account counter arguments.Do not reject a source because it makes an argument against you thesis.C. Choosing sources that cover the topic in depthProbably most books on Communicative Language Teaching mention WilliamLittlewood, but if this your topic, you will find that few sources cover the topicin depth. Choose those.D. Choosing sources written by acknowledged expertsIf you have a choice between an article written by a freelance journalist onTask-based Teaching and one written by a recognized expert like David Nunan,Choose the article by the expert.E. Choosing the most current sourcesIf your topic involves a current issue or social problem or development in ascientific field, it is essential to find the latest possible information. If all thebooks on these topics are rather old, you probably need to look for information inperiodicals.V. Writing a literature ReviewA. When you review related literature, the major review focuses should be:1. The prevailing and current theories which underlie the research problem.2. The main controversies about the issue, and about the problem.3. The major findings in the area, by whom and when.4. The studies which can be considered the better ones, and why.5. Description of the types of research studies which can provide the basis for the current theories and controversies.6. Criticism of the work in the area.B. When you write literature review, the two principles to follow are:1. Review the sources that are most relevant to your to your thesis.2. Describe or write your review as clear and objective as you can.C. Some tips for writing the review:1. Define key terms or concepts clearly and relevant to your topic.2. Discuss the least-related references to your question first and the mostrelated references last.3. Conclude your review with a brief summary.4. Start writing your review early.VI. 文献综述主要部分的细节性提示和注意事项英文文献主要部分细节提示：引言(Introduction)引言是文献综述正文的开始部分，主要包括两个内容：一是提出问题;二是介绍综述的范围和内容。

Review Topic Many theories have been proposed to explain what
motivates human behavior.
These themes are: incorporation of the self-concept into traditional theories of motivation, the influence of rewards on motivation, the increasing importance of internal forces of motivation, autonomy and selfcontrol as sources ofmotivation, and narcissism as an essential component of motivation. Although the literature represents these themes in a variety of contexts, this paper will primarily focus on their application to self-motivation.
什么是LiteratureReview（文献综述）？快到ddl你还懵？
什么是LiteratureReview（文献综述）？快到ddl你还懵？不知不觉，八月已经过了快一半了，还有不到一个月就要交dissertation，也就是毕业论文了。
在阅读了大量文献和确定研究方法主题后，作为dissertation的第一个大模块，很多小伙伴都在开始撰写Literature Review了。
最近，君君收到很多来自毕业生的消息，咨询如何写Literature Review，并觉得特别头疼这一部分。
今天，让我们一步一步剖析什么是LR怎么写好LR吧！首先，我们要明确什么是LR。
什么是LR01毕业论文作为学术性作文，LR部分需要向读者提供有关你主题的重要文献的分析性概述。
如果你的受众比你对该主题的了解少，那么你的目的就是教学。
当然啦，绝大多数同学做的研究项目属于这一种：如果受众（导师）比你更了解这个话题，那么你的目的是展示对该主题的熟悉程度，专业知识的贮备和智能。
# 将一个人的原创作品放在现有文献的背景下。
# 解释与您的主题相关的主要问题。
# 描述每项工作与正在考虑的其他工作的关系。
# 找出解释的新方法，并阐明以往研究中的任何差距。
# 解决之前看似矛盾的研究中的冲突。
# 确定哪些文献对理解您的主题做出了重要贡献。
# 指出进一步研究你的主题的方法。
LR要写什么？02简单来说，我们要牢牢记住一个词“结构合理well structured”你的想法必须在逻辑上从一个点流向另一个点，或是从一个点拓展散射开到几个相对于的研究问题上。
内容上我们主要有四大项必须满足概念：利用文献概述你正在考虑的主题，问题或理论。
归类：将你收集到的这些文献划分类别和概念，也就是按照Research Question归类关联：将前人的工作与你的工作，你想法之前的作品和你的研究点联系起来。
评估：对那些对理解和发展主题做出最大贡献的作品提供结论。
在写这四大部分的过程中，每当你计划将文献纳入你LR的过程中，先思考这几个问题：资格:这篇文章作者有什么资格来做出判断?中立:作者的观点是公正的还是有偏见的?可信度:作者的哪篇论文哪个观点令人信服，为什么?价值:作者的结论是否增加了你研究的问题的价值?看到这里，已经成功了一半啦！加油继续哦！内容上我们主要有四大项必须满足概念：利用文献概述你正在考虑的主题，问题或理论。
