As teachers of writing, the authors know that choices matter: the more choices they can give their students, the better their writing will be--and the better writers they'll become. Many teachers design their courses as writing workshops, so that students make choices about the genres they compose in. They structure writing assignments so that students make choices about topics and organization. They teach students to make choices about sentence structure, syntax, diction, and style. Choices matter for student writers. In their last column, the authors emphasized how professional writing instruction can prompt student writers to make genre choices in context. In this column, the authors focus on another set of choices for students learning about professional writing: document design decisions including choices about page layout, fonts, color, and the like.
