Support every statement you make with evidence. Because this is a research paper, there shouldn’t be any remarks that you make that cannot be supported by facts directly from your research. Supply ample explanations for your research. The opposite of stating opinions without facts is stating facts with no commentary. Although you certainly want to present plenty of evidence, make sure that your paper is uniquely your own by adding commentary in whenever possible.
Who would be reading this paper, should it be published? Although you want to write for your professor or other superior, it is important that the tone and focus of your paper reflect the audience who will be reading it. If you’re writing for academic peers, then the information you include should reflect the information you already know; you don’t need to explain basic ideas or theories. On the other hand, if you are writing for an audience who doesn’t know much about your subject, it will be important to include explanations and examples of more fundamental ideas and theories related to your research.
A research paper is different from a research proposal (also known as a prospectus), although the writing process is similar. Research papers are intended to demonstrate a student’s academic knowledge of a subject. A proposal is a persuasive piece meant to convince its audience of the value of a research project. Think of the proposal as the pitch and the paper as the finished product.
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.
