The best way to use research in a paper, or any context really, is to make a quote sandwich. The quote (or paraphrase, piece of evidence, example) should be situated between context and analysis.
Introduce: Where did your quote/paraphrased idea come from? Who said it? A doctor? A lawyer? A love expert? A magazine editor? Your bff? And in what context? What is the conversation surrounding this idea?
Quote/Paraphrase: I think this is self-explanatory. Don’t forget to use proper MLA citations! Even if it’s a letter, you can always edit them out of your real copy, but for class purposes, I will need to know that you know how to do them.
Interpret: How did you understand it when you did a close reading?
Analyze and Connect the Dots: What does this quote mean to your argument or inquiry? What does it add to your discussion? Why is it important? Why does it matter?
