Writing to learn makes it possible to show learning in writing. Much of the writing you will do in college and at work will ask you to demonstrate what you have learned. The success of that demonstration will depend on, among other things, revising your writing to show your knowledge to best advantage. When you have begun to see what you want to say(frequently this becomes clear at the very end of a first draft), it is time to start thinking about how to present your ideas to others. It is time to start thinking about revising.
Revising can be described as the most important(and frequently most neglected) part of writing. Novelists Doris Lessing has said that many novels miss greatness because authors are unwilling or unable to revise them. James Michener explains the importance of revision this way: "I have never thought of myself as a good writer. Anyone who wants reassurance of that should read one of my first drafts. But I' m one of the world' s great revisers."
Revising takes many forms. It means thinking about the audience for your writing. Who will read your work and why？ It also means developing an overall plan for the writing that will make your ideas clear. Often the organization of a first draft will reflect your process of discovery, but that may not be the best way to present your ideas to someone else. Revising also gives attention to the style. of language, to the structure of a paragraph, and to the shape of sentences and other forms that show learning to its best advantage.
Writing to learn and writing to show learning are never, of course, entirely separate processes. Writers frequently consider issues of demonstrating learning while writing to learn, and writing to show learning often leads to new under- standings. In drafting, for example, you may start thinking about what an audience will need to know in order to under- stand your point and change a word or a phrase to make your meaning clearer. But understanding the differences between writing to learn and writing to show learning is central to seeing writing as a process.
