 I don't know, like other teachers I've always struggled with getting good classroom discussions going. It can be very difficult to have a classroom discussions when you're not even sure if they've done the reading, and you're up there trying to get something going. What hypothesis is done for me is, like I said before, I can go before class, take a look at all those annotations, take a few notes about who said what, walk into the classroom and really get a classroom discussion going much more organically and successfully.
