Synthesizing (P138)
Synthesizing the sources
Writing a good literature review is to synthesize the past studies/sources.A novice student writer needs to pay attention to the following points.
1. Read actively to find similarities and differences of multiple texts on the same topic (problem or issue) in terms of arguments, definitions and explanations, causes and effects, advantages and disadvantages
2. Forge relationships among text materials, according to the purpose of synthesis.
3.Use one sentence which often functions as a topic sentence (TS) to summarize similar findings of several sources by using the multiple authors citation method .
4.
Use several sentences which often function as supporting
sentences(SS)to summarize views of findings of each text by using the
information-focused citation method or the author-focused citation
method .
Look at the following synthesis from two different literature review sections and you may find sources are synthesized in the TS-SS structure: beginning with a topic sentence (underlined)shared by different findings from various sources, followed by supporting sentences of evidence from the sources.
Numerous research studies demonstrate consistently that content-based second language teaching promotes both language acquisition (语言习得)and academic success (Grabe & Stoller, 1997; Kasper, 1994; Krueger & Ryan, 1993; Snow & Brinton, 1997; Stry-ker & Leaver, 1997; Wesche, 1993).Students receiving linked instruction perform better in language courses than those not receiving such instruction (Kaspern,1997 ). They reap the benefits of significant gains in the second language, e.g., in the receptive skills of listening and reading (Burger et al., 1997; Ready & Wesche, 1992) and in the productive skills of writing (Burger, 1989) and speaking (Burger & Chre'tien, 2001). They also achieve comparable or even better mastery of disciplinary content than ESL students or native English speaking students not receiving content-based language instruction (Andrade & Makaafi, 2001; Babbitt, 2001; Kasper, 1994; Winter, 2004).
(p138 )(The most successful research paper is one that uses many sources to support your ideas .This requires more than simply summarizing a single source material. A synthesis is a piece of writing that combine information from several sources. If you want to explain a concept or event, research from different sources can be synthesized to offer a well-rounded explanation. If you want to argue a point, you can synthesize several pieces of research that back the point. Hence, in an academic synthesis, you must infer and then make explicit the relationships among separate sources.)
