Most research papers begin with a thesis statement at the end of an introductory paragraph. Even if it’s not a requirement, it’s a good idea to write a thesis statement as you begin to organize your research. Writing the thesis statement first is helpful because every argument or point you make in your paper should support this central idea you’re putting forward.
Whenever possible, look for peer-reviewed empirical research. These are articles or books written by experts in your field of interest, whose work has been read and vouched for by other experts in the same field. These can be found in scientific journals or via an online search.
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.
Although it may seem counter-intuitive, writing your introduction first may be more difficult to accomplish than starting with the meat of your paper. Starting by writing the main points (focusing on supporting your thesis) allows you to slightly change and manipulate your ideas and commentary.
