> abandoning traditional lecturing in favor of active learning
I think this is a misunderstanding of what "lecturing" is supposed to do. It's supposed to _introduce_ you to the material at a high level. Think of it as of skimming a scientific paper. The actual "learning" is something you do on your own after the lecture (although some lecturers require that you _first_ study the subject and then listen to the lecture), and when doing assignments. IOW, it's not a be all end all, and it shouldn't be treated as the only thing you need to learn the material.
