The introduction is, in many respects, the conclusion written in reverse: start by generally introducing the larger topic, then orient the reader in the area you’ve focused on, and finally, supply the thesis statement. Avoid repeating exact phrases that you already used in the conclusion.
Every type has a different aim. An argumentative work has to show a few sides of a particular issue and provides arguments in favor of one of them, a definition project aims to provide a clear explanation and analysis of one specific matter. Cause and effect research paper writing requires you to present a logical chain of causes and effects that relate to the selected issue, while reports simply outline a study (or studies) that were conducted previously. Interpretive papers are similar to definition ones. Compare and contrast ones, as a rule, describe the same issue from the perspectives of two different authors (scientists), while analytical research paper writing requires you to create a deep analytics of various opinions regarding the same issue.
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.
Now that you have carefully worked through your evidence, write a conclusion that briefly summarizes your findings for the reader and provides a sense of closure. Start by briefly restating the thesis statement, then remind the reader of the points you covered over the course of the paper. Slowly zoom out of the topic as you write, ending on a broad note by emphasizing the larger implication of your findings.
