It sounds like a good problem, right, but I wondered if my students were learning as much as they should.  After adding TAGteaching into my classes, either teaching pet parents or Dog Trainers, I noticed we zoomed through our daily course material.  Interestingly, this allowed additional break periods, which increases learning, I think.  Was I doing something wrong?  But why were we moving so fast?  Were students learning and retaining?  What to do with all that extra time?
