Write a thesis for your essay. Choose the best idea from your research and write a concise and succinct statement that best describes your assertion about communication situations. For example: "The model of Myerson can be seen as a directed communication situation where the worth of any permutation of a set of players is the same and, in the directed graph, between any pair of players there is either no arcs or two arcs, one going in each direction."
Outline the essay according to your research and thesis. Write one-line sentences for paragraph descriptions, along with short bullet points attributing each paragraph's contents.
Draft the introduction of your essay on communication situations. Start by telling the audience what the essay is about and why it is important enough to read. Build up your issue and introduce the thesis.
Write the body paragraphs of your essay according to your outline. Ensure each paragraph focuses on a single idea supporting the thesis. Begin each paragraph with a topic sentence that introduces the content of the paragraph.
Conclude the essay with a paragraph providing final thoughts on the subject and thesis. Revert back to the introduction to give the essay a sense of completion. For instance, use the final paragraph to give the introduction a different, more enlightened context.
