This is appropriate because outcomes are unknown until you've completed the study. 63-70; Resources for Writers: Introduction Strategies. However, anyone can look a word up in the dictionary and a general dictionary is not a particularly authoritative source because it doesn't take into account the context of your topic and doesn't offer particularly detailed information.
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. Also, placed in the context of a particular discipline, a term or concept may have a different meaning than what is found in a general dictionary.
Study limitations can exist due to constraints on research design or methodology, and these factors may impact the findings of your study.
However, many researchers are reluctant to discuss the limitations of their study in their papers, feeling that bringing up limitations may undermine its research value in the eyes of readers and reviewers.
In this way, the roadmap acts as a type of promise to yourself and to your readers that you will follow a consistent and coherent approach to addressing the topic of inquiry.
Refer to it often to help keep your writing focused and organized.
Since all studies face limitations, being honest and detailing these limitations will impress researchers and reviewers much more than ignoring them.
Some limitations might be evident to researchers before the start of the study, while others might become clear while you are conducting the research.
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. Centre for Applied Linguistics, University of Warwick; Samraj, B.
It is often useful to review the introduction late in the writing process. Massachusetts Institute of Technology; Sharpling, Gerald. “Introductions in Research Articles: Variations Across Disciplines.” Giving the dictionary definition of words related to the research problem may appear appropriate because it is important to define specific terminology that readers may be unfamiliar with.
