Step 1: Purpose of Paper
Before you begin this step, think to yourself: "what is the goal of this paper?" Now, write down your answer to that question. In your introduction, try to point out the exact sentence you answer that question. Could you find it? If so, great! If not, how could you add a sentence or two to explain your goal in this paper?
Step 2: Organization
Try creating an outline of your paper by summarizing each individual paragraph, starting with your introduction, into one sentence each. When you read through all of these sentences in order, do you feel your paper makes sense? If so, great! If not, how could you rearrange your ideas or add more information in order to create a more clear organization?
Step 3: Development of Each Paragraph
Try reading through each paragraph individually, and see if you feel each paragraph's main idea is sufficiently developed. If they are, great! If not, you may want to consider adding more information.
Step 4: Grammar
Now that the content has been addressed, try reading through the paper and seeing if there's anything you think someone might have trouble understanding. It may help to try reading aloud, or have someone else read your paper.
