the answers are already appearing!
Seriously? This is a video? Words and an image... More words appear... More words appear... More words appear... Then the solutions start appearing before I even have a chance to realize I'm supposed to do something. If you can't make the escalator move then what's the point? I'd much rather they let the kids control words appearing, especially the answers! I don't understand how anyone thinks this is progress.
I did find an iBook series that is heading in the direction of what I'm imagining for textbooks on tablets. iShortcut has embedded geogebra applets throughout, quizzes that students can take mid-unit (with an answer checker) and an overall clean design. It lacks pedagogy, but for a mathematician/chess player it's impressive. Maybe someone wants to work with him to get the questions and applets to appear before the definitions and theorems? And feedback rather than just "incorrect" on the quizzes would be nice too.
There's potential for ebooks, but we're so not there yet.
