Research paper writing consists of several stages. The first stage consists of choosing a relevant topic and making a thesis statement that shows the objectives and goals of your investigation. It is followed by the research and experimental stage during which a student studies the matter, works with relevant literature, and collects data for the written part of this project. Then you have to write the paper itself. The last stage is less stressful as you already have all the necessary information and only need to analyze and present it in a proper manner, however, it requires knowing and following the basic principles of academic writing.
To draw a parallel, a lawyer researches and reads about many cases and uses them to support their own case. A scientist reads many case studies to support an idea about a scientific principle. In the same way, a history student writing about the Vietnam War might read newspaper articles and books and interview veterans to develop and/or confirm a viewpoint and support it with evidence.
Depending on your paper rubric, class guidelines, or formatting guidelines, you may have to organize your paper in a specific way. For example, when writing in APA format you must organize your paper by headings including the introduction, methods, results, and discussion. These guidelines will alter the way you craft your outline and final paper.
Generally, speaking, there are two types of research paper: an argumentative research paper or an analytic research paper. Each requires a slightly different focus and writing style which should be identified prior to starting a rough draft.
