Once you understand what you’re being asked to write in your research paper, it’s time to decide what to write about.
If you have two main points in your thesis, three or five main sections might not work for your research paper. If the assignment asks you to introduce a topic, explain different opinions on the topic, and then choose and explain your opinion, then your paper probably needs three main sections, one for each of those objectives.
Invest time in writing your thesis statement—it’s the main idea of your paper, from which everything else flows. Without a well-thought-out thesis statement, your paper is likely to end up jumbled and with an unclear purpose.
If you want to find helpful and reliable sources of information, the library is literally the best place to look around. There are numerous books, published articles, journals and etc. that you can choose from about your chosen topic.
Working with your teacher and asking them for help is an often overlooked resource when it comes to writing research papers. Be sure to take advantage of this help; your paper will be all the better for it.
