2、iew,1 Writing a literature review,Unit 4 Writing a Literature Review,Aliterature review is a very important part of the research project.It may be a self-contained review or a part of the introduction to an academic essay.In either case,its purpose is to demonstrate a clear understanding of the topi
3、c being investigated.Namely,your literature review must tell what has been done on the topic,what different scholars have said about their own research,what major findings have been published,and what controversial areas exist.A good literature review can enhance the credibility of your research by
4、indicating that your present study is based on a thorough and critical knowledge of what has been done in the field.,Before writing,to be critical,you must ask questions like these about each book or article you read:Is the problem clearly defined?Is its significance clearly established?Could the pr

12、cle(s)do you find most reliable and trustworthy?Why?,2 Writing a self-contained literature review,Unit 4 Writing a Literature Review,There are two types of literature reviews.One is an independent,self-contained report,and the other is a part of an academic essay.A self-contained literature review r
13、eports the past research activities on the topic being investigated,especially their studies and findings.To some extent the literature review itself is an essay.Hence it should be written in detail,including the methods apart from findings and conclusions.The steps of writing a self-contained liter
14、ature review are the followings:1)write a summary of each article you have gathered for your literature review;2)combine the summaries logically,by using connective phrases or sentences;3)write an introductory paragraph,including the definition of the topic and its background information;4)make your
15、 comments,if necessary,on the past studies.,TASK1,Read the following self-contained literature review and answer the questions belowo1 Which sentences supply the background information about the literature review?2 What is the objective of the literature review?3 How many articles does the writer re

23、of the target.,3 Writing a literature review as a part of an essay,Unit 4 Writing a Literature Review,Unlike a self-contained literature review,a literature review as a part of an essay is not a mere combination of summaries of material sources.The choice of previous research and even ideas and find
24、ings in a previous article is completely based on the research questions you set out to answer in your essay.In other words,you should avoid including in your literature review all ideas and findings in the previous articles.Most important is that such a literature review should contain your critica
25、l comments on the previous studies,especially their weaknesses or limitations so that your present study will be more rational and significant rather than being a repeat.The literature review as a part of the essay will be shorter than a self-contained literature review,introducing the main findings

27、 review?4 What findings does each article give respectively?5 Which sentences does the writer use to connect these findings?,Sample:Content-based instruction:Long-term effects and outcomes,Content-based instruction(CBI)is an alternative approach to teaching English.In such an approach,language teach
28、ing is integrated within discipline-specific content courese.The major goal is to equip students with academic literacy skills across the curriculum.CBI has gained wide acceptance in U.S.undergraduate institutions.Its cognitive and linguistic effects have been studied and reported.Numerous research
29、studies demonstrate consistently that content-based second language teaching promotes both language acquisition and academic success(Grabe Ready&Wesche,1992)and in the productive skills of writing(Burger,1989)and speaking(Burger&Chretien,2001)They also achieve,comparable or even better mastery of di
30、sciplinary content than students not receiving content-based instruction(Andrade Winter,2004).However,the literature on CBI has focused mainly on its most immediate effects,i.e.,the outcomes of one or two semesters in which content-based instruction was provided.Studies on the sustained or long-term
31、 benefits of content-based language instruction are scarce.As variations of the content-based ESL curriculum have evolved over the years,the interest in the longer-term studies has grown.Those of us who teach in content-linked programs are especially interested in determining its effects on future l
32、earning.For example,will the significant gains in the second language as a result of CBI give students an advantage in subsequent English courses?How will CBI impact students future academic performance?Will it translate into sustainable academic success,often judged by measures such as GPA and grad
33、uatio rate?,4 Citation,Unit 4 Writing a Literature Review,Citation,the way to use sources,is a major part of a literature review and is also frequently used in supporting your arguments.There are two methods.One is quoting(copying the exact words of the author)and the other is paraphrasing(rewriting
34、 what the writer said in your own words).Though both are possible and acceptable,paraphrasing is much more common than quoting in academic writing.Direct copying is not strongly recommended unless the writers words are special.This is often the case with strongly stated definition or opinions.Citati
35、on consists of two parts:i)citation of the content and ii)documentation of its source.In the following paragraph,for example,names of the authors and dates in parentheses are the in-text documentation and the rest is the content of citation.,Several detrimental effects of GM crops had been showed on
