Audience, the for whom of any piece of writing, is closely connected to purpose. Consciously or unconsciously, writers use their knowledge of audience in determining purpose. Much academic writing is tailored to an audience of one—the instructor. Do you remember justifying a low grade on a paper by claiming you "didn't know what the instructor was looking for?" The reality is that the instructor is an important member of the audience for student writing. But when we can expand the audience to include classmates, other members of the academic community, Internet readers, and other real or imagined members of the community at large, we add significance to our students' writing—a purpose that extends beyond the exchange of a paper for a grade. Investing our students with a meaningful purpose for an interested audience will help them, in turn, to establish focus.
