Research articles (RAs) share new findings from a study and prove that the discoveries are valid and significant (Van Enk and Power 2017). They overview the context for the research, say what question was studied, how the research was done, what was discovered, and why it matters.
Unlike researchers, undergraduate students are not expected to produce new knowledge. Still, they are often expected to read and write RAs as a way of familiarizing themselves with the subject knowledge, methodological approaches, and theoretical orientations of their chosen area of study.
This popular template for structuring RAs begins with the Introduction and proceeds through Methods, Results, and Discussion sections. Day (1989) locates early traces of IMRaD in the writings of the 19th-century scientist Louis Pasteur, but it is difficult to attribute the model in its current form to any one source. Instead, it seems likely that IMRaD was standardized alongside the scientific method itself, such that the model “began to be adopted by scientific journals around the 1940s, and quickly became the dominant format for research papers in a majority of leading scientific journals by the late 1970s” (Wu, 2011, p. 1346). The IMRaD model is effective because each section of the template corresponds with a stage in the scientific process.
Not all RAs follow the IMRaD model, but it is a common format in STEM fields (science, technology, engineering, and math) and some social sciences. The model helps scientists to write clearly about their research by providing a structured way to present information with minimal bias. Many peer-reviewed journals require authors to conform to IMRaD, sometimes mandating the use of headings and subheadings to identify the sections.

The introduction answers the question, “Why was this study done?”
As Swales (1990) demonstrates in his Create-a-Research-Space Model, introductions fulfill three key objectives:
๐ Demonstrating familiarity with the existing state of knowledge in their field;
โ Identifying a gap, lack, problem or need in the pre-existing state of knowledge; and
๐งฉ Making an original contribution which fills the gap and/or addresses the problem
Introductions often explicitly feature a research question, hypothesis, or—especially in student research papers—an argument/thesis statement.
The method section answers the question, “How was this study done?”
Smagorinsky (2008) calls the methods section the “conceptual epicentre” of the RA, which “serve[s] as the nexus for other sections of the paper’s organization and alignment” (p. 390). A comprehensive methods section describes the study as it was carried out, ideally with a level of detail which would allow for the study to be repeated by others. It also accounts for the data (or object of study) and explains the interpretive framework and/or analytical approach which will be applied.
The results section answers the question, “What did you find by doing your study?” The results are the outcome of the study as described in the Methods section.
The discussion answers the question, “What conclusions did you draw based on the results?” The discussion offers an interpretation of the results, explaining their significance in relation to the research question. It points to strengths and limitations of the study, addresses potential implications or consequences of the findings, and suggests possible directions for further research.
