What Is a Research Paper Introduction
The introduction of a research paper is the first section that presents the research topic, explains why the study matters, and outlines the main research question or thesis statement. It prepares readers for the detailed discussion that follows in the body of the paper.
A strong introduction typically answers three questions:
- What is the topic of the research?
- Why is this topic important?
- What will the paper prove or analyze?
Main Purpose of the Introduction
| Purpose | Description |
|---|---|
| Context | Provide background information about the topic |
| Problem | Identify the research problem or gap |
| Direction | Explain the research objectives and thesis |
