Avoid using many long, direct quotes. Although your paper is based on research, the point is for you to present your own ideas. Unless the quote you intend on using is absolutely necessary, try paraphrasing and analyzing it in your own words instead.
To draw a parallel, a lawyer researches and reads about many cases and uses them to support their own case. A scientist reads many case studies to support an idea about a scientific principle. In the same way, a history student writing about the Vietnam War might read newspaper articles and books and interview veterans to develop and/or confirm a viewpoint and support it with evidence.
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.
The good news is, once you reach this point in the process you’re likely to feel energized by all the ideas and thoughts you’ve uncovered in your research, and you’ll have a clear direction because you’ve taken the time to create a thesis statement and organize your presentation with an outline.
