I've glanced through your books, but I'm tackling Understanding Comics again before I really study the new ones. My first approach will be to teach the concepts in McCloud's first and third chapters, as I've looked more closely at the book.
By the way, there is a high school Watchmen study group forming with some teachers and students. It's pretty exciting. Two teachers who never read comics are reading it and are astounded by its complexity. Perhaps we can parley that into an increased use of GNs at Williamsport High School.
