So then it just sounds like glorified notes from the teacher. We've been giving students study guides and notes for a while now; many barely use them. If the tool allows them to read the notes, understand the material, and prepare them to take and pass a test (without needing said notes in front of them), great! I'm all for it. It's overkill, but whatever. If we care about what students actually learn in our classrooms (and I'm far from convinced that that is the aim of school) then we should be teaching them how to a) listen as smarter people instruct them, b) take good notes about what the smarter people are saying, c) study so you have the essential material memorized from the lecture, book, video, or internet material that's being used in class, and d) be prepared and ready on test day to show what you've learned. That's the secret sauce of learning. If this new tool helps in that endeavor, great! Because currently, students from K to post-doc are getting harder to teach.
