Flipping the flipped classroom

I've enjoyed tweaking the flipped classroom concept.  It is a stellar idea, but isn't 100% effective for all students (but what is?!)  One thing that has worked well with our AG2 class is allowing time to watch the videos in class, but then spending some one-on-one time during and/or at the end of the videos with the students who need more hands-on interaction with the concept.  Sometimes, we discuss the concept and do sample problems instead of watching the video -- it depends on the student and the concept.
