Robert Talbert (Twitter @RobertTalbert) has been tweeting about how he has a "12-week approach" to class, where the last two weeks are a chance for review, reflection, re-doing work.
He said today that "We do what we can, and act with students in mind", which I think is a great motto -- we have to work within the constraints of our institution, discipline, etc, but as long as we are trying to be centered on student learning, we can find a way to make it work as best as possible.
