I participated in a Writing Across the Curriculum (WAC) workshop series just recently, and I received this book as part of the "class". We actually only read the first 25% of the book as part of the workshop, but I couldn't put the book down. And though it might be mean to say, I can tell you that this book was more significant and useful than the workshop itself. Burn!
Anyway, I've been teaching writing for the past four years and have been itching to make some changes. This book helped me to make some practical changes. It's important to note that this book is most helpful for teaching writing to college students. And while the authors themselves seem to regularly teach relatively small writing classes (under 17 students, typically; sounds like a dream to me), they do acknowledge and have strategies for writing instructors with larger class sizes.
What I really loved about this book is that it provides so much context. It's easy to complain about our students and their lack of good work, but the authors really try to debunk that myth by reminding you that college students have an awful lot going on, and they're young adults. Instead of playing the blame game, it's about working with what you have. And it means that teachers, occasionally, have to change their ways in order to be current and effective. That's true in other areas of study; why would it be any different for writing?
There are a lot of excellent strategies for writing assignments, descriptions for those assignments, and assessment for those assignments. There are a lot of examples from different types of disciplinary writing classes (or just discipline-specific classes that necessarily require written assignments), which can be helpful for many. (I didn't find them directly useful, but I'm sure some would.) There is extensive coverage of using multiple drafts, strategizing, instructor feedback, and peer work. Again, a handful of the activities that they talked about (class presentations about rough drafts) were interesting but just not possible in a class with more than 15 students, but I really like the ideas.
I mean, it comes down to what you want as an instructor. I'm tired of fighting an uphill battle with my students, and I really don't like reading their crappy work. It might be crappy because I've not done a good job framing the assignment. And sure, some of them might be generally crappy, but I kind of doubt it. If you teach a writing course in college, you can't go wrong with this book. I also think it's a good idea for teachers of classes that are not specifically writing classes. It's creative and practical, and I am keeping this book by me as I cleverly revamp my entire class.
