One of the first steps in crafting an effective essay is asserting a controlling idea. The controlling idea of the essay states your driving opinion, belief or argument regarding the essay topic. A strong controlling idea is broad enough to include multiple examples and perspectives, but focused enough to keep the essay on a logical and easy-to-follow track. Once you've located your controlling idea, you are prepared to extend the idea into a thoughtful, well-rounded essay that provides evidence to support your position.
Prepare a graphic organizer to provide a visual guide to your essay. One approach to a graphic organizer is a box web. At the top of a piece of paper, write your broad topic, such as "Romeo and Juliet". Draw a line from the topic to a box. Draw three lines from the box to three smaller boxes. Draw three additional lines connecting the three boxes to a single box at the bottom of your paper.
Write your controlling idea in the first box of the organizer. The controlling idea is the position, opinion or argument you will defend in your essay. For a paper on "Romeo and Juliet," a controlling idea might be "Juliet is a feminist character" or "'Romeo and Juliet' is Shakespeare's most tragic play." The controlling idea should not be a simple statement of fact, but rather an arguable position that asserts your stance on the issue.
Write a concrete example in each of the subsequent three boxes that supports your controlling idea. The examples may be quotations from a text, excerpts from research papers or statements from experts that support your position. Use only one example per box. Beneath each example, write a phrase that demonstrates how the example supports your controlling idea.
Rephrase your controlling idea in the final box of the graphic organizer. The statement should reassert your position but sound distinct from your controlling idea statement. If your controlling idea statement was "'Romeo and Juliet' is Shakespeare's most tragic play," your rephrasing statement might read, "Both the number and the poignancy of the deaths in 'Romeo and Juliet' make the play Shakespeare's most tragic work."
Refer to the first box in your graphic organizer to write your thesis statement in your opening paragraph. The thesis statement should contain both the general topic of your paper as well as your controlling idea. A thesis statement might read, "Though Shakespeare composed many tragic plays, 'Romeo and Juliet' stands alone as his most tragic work." Write at least three subsequent sentences that clarify your first statement, summarize the direction of your essay and conclude the paragraph to transition into specific examples.
Refer to your first supporting evidence box to compose your first body paragraph. The body paragraph should appropriately cite your piece of evidence and clearly connect it to your controlling idea. Include a concluding sentence that firmly reasserts your controlling idea based on the evidence. For example, your first body paragraph might conclude, "The depiction of Juliet as youthful and innocent makes her subsequent death even more tragic than the deaths of less sympathetic Shakespeare characters."
Compose an additional two body paragraphs using your two remaining evidence boxes in the same way outlined in Step 6.
Conclude your essay with a final paragraph that summarizes your main arguments and asserts your controlling idea as rephrased in your last text box in your graphic organizer.
