I've come across similar experiences in the K-12 space.<p>Flipped classroom models almost always also invariably involve more work for the students, who quickly shun it as well.<p>For an effective implementation, the flipped model class should flip the experience in its entirety: You will do at home 100% of what we'd do in lecture, and class for 100% of what you'd do at home. That is, no more homeworks, no more readings, etc., that gets done in class or in labs. Homework is literally just for watching lectures. That model has a much higher chance of success.
