The introduction of a research paper serves several key purposes: 1) It provides context by summarizing previous research and background on the topic. 2) It states the specific research problem or question being addressed. 3) It explains the significance and importance of studying this problem. The introduction typically includes 4 components - establishing the problem, reviewing existing research and perspectives, identifying a gap in current knowledge, and stating the research question and hypothesis. It is important that the introduction clearly positions the research and knowledge claim in a way that engages the reader and shows why this research is valuable.
