I give it 4 stars

What I liked most about the "flipping the classroom" course  was the confirmation of many of the problems I have encounted with the traditional classroom style.  Students usually only have about a 15 minute attention span before they start to check out. Traditionally lectures are  scheduled in one hour segments.  Also if a student misses an important concept during a traditional lecture he or she cannot "rewind".  I find tht most students are too embarrased to  ask for clarrification during the lecture.  Additionally I usually do not have a chance to evaluate the  students' grasp of the material until an exam is given.  At this point it is usually too late to go back to relearn the material  because more lectures have been scheduled on different topics.
