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.
If you choose a topic, begin researching, and realize that it isn’t the right decision for you for some reason, don’t fret! Although it requires a bit more time, you have the ability to change your topic even after you begin researching others.
APA format is used by researchers in the social sciences field, and requires in-text citations as well. It ends the paper with a “references” page, and may also have section headers between body paragraphs.
Chicago formatting is used mainly for historical research papers and uses footnotes at the bottom of each page rather than in-text citations and works cited or references page.
