Issue trees help you generate new ideas when you see gaps in the structure of your argument. Paragraph Level Organization Paragraphs are individual units that, like essays, have distinct shapes and purposes. The main purpose of any paragraph is to advance the thesis of the essay in some way. However, this does not mean that all paragraphs will develop ideas at the same level or degree of complexity. You may use one paragraph to introduce a top-level idea, several more to explain and develop that idea, and then a transitional paragraph to sum up and move to the next idea.
Readers do expect paragraphs to follow a pattern and the following are some of the most popular.
They are not necessarily the best for every situation. As the author, you will have to choose an organizational pattern that best serves your purpose. In this familiar pattern, the author introduces a topic, refines or restricts it, and then illustrates or develops it in the rest of the paragraph. With a long or complicated paragraph, the author may come back to the topic at the end and create a TRIT pattern. In this type of paragraph, the writer simply presents a problem and then solves it.
