There is no one answer to this question as chapter 1 of a research paper can vary significantly depending on the particular field of study and the specific research design that is being used. However, in general, most research papers will have 5 main sections in chapter 1: (1) an introduction, (2) a literature review, (3) a methodology section, (4) a results section, and (5) a discussion section.
The introduction should provide a general overview of the research topic and the specific research question that the paper is attempting to answer. The literature review will discuss previous research that is relevant to the current study. The methodology section will describe the specific research design that was used and explain how the data was collected and analyzed. The results section will present the findings of the study. The discussion section will interpret the results and discuss the implications of the findings.
