The document discusses the flipped classroom model of instruction. It begins by outlining challenges in traditional classrooms like disengaged learners and large class sizes. It then defines the flipped classroom as exposing learners to new material like videos prior to class, and using class time for hands-on activities. Benefits include maximizing class time for active learning and individualized attention. The document provides examples and resources for implementing flipped classrooms, and discusses assessment and deciding which lessons to flip. Overall, the flipped classroom aims to shift lower-level learning outside of class in order to use class time for higher-order thinking.
