I enjoyed your response. Have you taught Calculus on the block? How have your AP scores been affected. The gentleman who responded has seen the effects of the block on an AP program that expects the students to learn the content and pass the test. It has nothing to do with being creative! It has to do with attention span. No matter how varied the activities, it is difficult to keep one's attention span for more than an hour. The business world figured this out long ago. It also has to do with losing total class time. I'm sure you agree that the more contact time with students, the better chance they have to learn the material.
