A single main point doesn’t have to be kept to a single paragraph, especially if you are writing a relatively long research paper. Main ideas can be spread out over as many paragraphs as you deem necessary.
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.
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.
An argumentative research paper takes a position on a contentious issue and argues for one point of view. The issue should be debatable with a logical counter argument.
