The premise of this WAC website--and of the WAC movement overall--is that effectively designed writing assignments enhance our teaching and our students' learning. While acknowleding that assigning and evaluating writing is time consuming, this page offers a number of persuasive arguments why writing assignments are part of effective teaching and learning.
That's a good question, actually. Let's be honest–-there are, after all, many reasons why we might not want to assign writing in our courses. And many of those reasons have to do with the limited time we all can devote to teaching. Designing writing assignments and responding to student writing take valuable time—lots of time if we do them carefully.
