Comparative Analysis of Two Research Articles

Research articles (RAs) have their own structure and format, and they are composed of several parts or sections: title, abstract, acknowledgements, introduction, literature review, methods, results, discussions, recommendations, references, and appendixes. Swales (1990) and Swales and Feak (1994) provide academic writers with a description of the structure that RAs should have as well as guidelines about the elements which should be present in each section. Considering the introduction in particular, they claim that it should include three moves or cycles: establishing a research territory, establishing a niche, and occupying the niche. As regards the methods section, they claim that it is usually divided into three subsections: participants, materials, and procedure. However, when examining RAs it is possible to see that sometimes authors do not follow some of those conventions. Being able to analyze the structure of each section in an RA and its linguistic characteristics is crucial for student writers to learn how to write an RA properly. This paper intends to provide a comparative analysis of two research articles, placing the focus on the introduction and methods sections in each piece of work. The elements included in each section have been examined, as well as the way they have been sequenced, in order to identify whether the authors have included the components that should be present in each section, and whether they have respected the order in which those components should be presented in an RA.
In the article “The Effects of Captioning Videos Used for Foreign Language Listening Activities”, Winke, Gass and Sydorenko (2010) present an introduction that  includes the most important elements that according to Swales (1990) and Swales and Feak (1994) an introduction to a research article should have: establishing a research territory, by stating the present state of arts, referring back to what has been done and showing relevance for the study; establishing the niche by indicating the motivations for the study, indicating the gap that has been found in the area, and formulating questions about the situation; and occupying the niche by describing what the present research is about. However, though in most research articles the purpose of the study is usually mentioned in the last move in the introduction, in this case it has been presented at the beginning, with the phrase: “The purpose of this study is to investigate L2 learners’ use of captions while watching videos in a foreign language.” (Winke, Gass &Sydorenko, 2010, p. 65). This introduction seems to be structured in a general-specific movement, going from the purpose statement and a general discussion of the topic to particular questions. Furthermore, despite the fact that some past research is mentioned and some research questions are formulated in the introduction, there is a separate literature summary and research questions section after the introduction. Although the authors seem to have written a quite detailed and complete introduction, other elements could have been provided in the last move, such as a more detailed description of the nature of the research, explaining the reasons for selecting that type of research study, an announcement of main findings, and an indication of the research paper structure.
In the article “ADHD Drugs and Serious Cardiovascular Events in Children and Young Adults”, Cooper et al. (2011) present a very brief introduction which has no heading to identify it.  The introduction should be more complete as it “is the part of the paper that provides readers with the background information for the research reported in the paper. Its purpose is to establish a framework for the research, so that readers can understand how it is related to other research” (Wilkinson, 1991, p. 96, as cited in Pajares, 2007, p. 1). There is no literature review in this article, just some brief references to past research, as it can be observed in this sentence: “Although case reports from adverse event reporting systems can be an important source for identifying medication safety signals, they cannot reliably quantify risk.” (Cooper et. al., 2011, p. 1896) from Canada and the United States that have included cases of sudden death, myocardial infarction, and stroke in conjunction with the use of these drugs have raised concern about their safety” but no author citations are provided, and this is a serious weakness as “the review of the literature provides the background and context for the research problem. It should establish the need for the research and indicate that the writer is knowledgeable about the area” (Wiersma, 1995, p. 406, as cited in Pajares, 2007, p. 3). Furthermore, though three moves can be identified in the introduction to this article (creating a research space, establishing a niche and occupying a niche), other elements could have been included in this introduction too, such as a description of the research structure and the reasons for choosing that type of research.
The methods section in the article written by Winke, Gass and Sydorenko (2010) includes the main elements that Swales (1990) and Swales and Feak (1994) state are usually included in that section: the participants, materials and procedure. However, the methods section in this article also includes supplementary elements, such as a scoring section and an analysis section. Both the sources of data and the collection and analysis of data are included. A table is used to provide specific information related to the participants, and a diagram is used to provide a clear account of the study procedure.
In the article written by Cooper et al. (2011), the methods section is also very detailed and complete, though it has a different layout from the one commonly used in research articles. It includes data sources, the study population, information about the use of study drugs, study end points, a study oversight and a statistical analysis. The information related to the sources of data, collection and analysis of data are included in those sections. Tables are used to provide specific information about the participants, as well as some graphs that clearly show specific data related to the study.
In conclusion, both articles have a quite complete and detailed methods section, and though each one has a different style and layout, both include the main elements that must be present in the methods section of a research paper. However, the introductions are quite different in each article. While the introduction in the article written by Winke, Gass and Sydorenko (2010) is quite complete, including the main information that an introduction to a research paper should have, the article written by Cooper et al. (2011) has a very weak introduction, which is very brief. Though the latter intends to include the main elements that should be present in an introduction and in the right order, the information given is quite scarce, particularly as regards the past research, where neither a literature review nor citations have been included
