The Writing Center. Peter Redman. London: Sage, , pp. Demystifying the Journal Article. Inside Higher Education. Structure and Writing Style I. Structure and Approach The introduction is the broad beginning of the paper that answers three important questions for the reader: What is this? Why should I read it? Think of the structure of the introduction as an inverted triangle of information that lays a foundation for understanding the research problem.

Organize the information so as to present the more general aspects of the topic early in the introduction, then narrow your analysis to more specific topical information that provides context, finally arriving at your research problem and the rationale for studying it [often written as a series of key questions to be addressed or framed as a hypothesis or set of assumptions to be tested] and, whenever possible, a description of the potential outcomes your study can reveal.

These are general phases associated with writing an introduction: 1. Place your research within the research niche by: Stating the intent of your study, Outlining the key characteristics of your study, Describing important results, and Giving a brief overview of the structure of the paper. This is appropriate because outcomes are unknown until you've completed the study.

After you complete writing the body of the paper, go back and review introductory descriptions of the structure of the paper, the method of data gathering, the reporting and analysis of results, and the conclusion.

Reviewing and, if necessary, rewriting the introduction ensures that it correctly matches the overall structure of your final paper. Delimitations of the Study Delimitations refer to those characteristics that limit the scope and define the conceptual boundaries of your research. This is determined by the conscious exclusionary and inclusionary decisions you make about how to investigate the research problem.

In other words, not only should you tell the reader what it is you are studying and why, but you must also acknowledge why you rejected alternative approaches that could have been used to examine the topic. Obviously, the first limiting step was the choice of research problem itself. However, implicit are other, related problems that could have been chosen but were rejected. These should be noted in the conclusion of your introduction.
