I still believe that being in the real-time physical presence of instructors and fellow colleagues improves learning - humans are a social species. However, I do think that moving rote learning out of the classroom and instead using class time for active learning activities will produce deeper learning. There is ample published evidence to support this claim. Interesting that students of Minerva indicate that attending class is exhausting because there is never a moment when they can let their attention wander - active learning requires focus on the task at hand whether that is solving problems or discussing learned concepts with fellow students. Forty-five minutes of exhaustive focus on learning, however, will likely pay dividends later when the learning, knowledge, skills are still deeply embedded within students, accessible when needed during their post-university lives.
