That's actually more-or-less the "traditional" british and american method of teaching (at least at the college level); historically, one was expected to show up in class having already studied the material to be discussed and prepared with questions to ask about points that were unclear. I'm not sure at what point it got "flipped" around to the current state where students expect to learn the material in lecture and then study their notes, but attempting to flip it back seems like a good idea.
