The flipped classroom has developed a solid following, but implementing it in the higher education setting, where class sizes can be quite large, still presents formidable challenges for the venturesome instructor. While recently published results tend to focus on class sizes of 25-35, this paper introduces a novel approach that effectively scales to class sizes of 50-60 and possibly more. In addition, the in-class real-time assessment of student performance, integral to this model, provides a motivation for students to complete the pre-class work thus insuring the effective use of active learning elements during class time.
