I'm at the International Society for Technology in Education conference, at the San Diego convention center. So far the sessions have been up and down, some really thought - provoking, others just so-so. Right now I'm waiting for the session on flipped classrooms, which seems to be the hot topic here. I just left a session on delivering instruction in blended and fully online classes, which left me with the question: should blended and online classes be part of the same continuum, or should they use separate models? Our district's answer to that will make a huge difference in how we proceed.
