Many students find the writing of an introduction, especially for a demanding paper such as a research paper, to be a very challenging task. If one knows the strategies to use in writing solid introductions, this part of the research paper can be as easy to write as the other sections of the paper. For a research paper, the introduction paragraph is usually a half page in length although it can sometimes be longer depending upon the overall length of the paper and the required background information needed for the introduction. Just like other kinds of papers, the introduction of a research paper begins with statements that present the primary issue being explored and ends by offering the hypothesis or research questions on which the study or research is to be based. The introduction paragraph of a research paper, and indeed of any other kind of academic paper, should always offer a theoretical framework for the research and enable its reader to gain a clear understanding of the purpose for the research. Without a well-written introductory paragraph, it would be very difficult for readers to determine what the paper is about and to follow the presentation of ideas and evidence.
