This document discusses the flipped classroom model of education. It defines the flipped classroom as an approach where traditional classroom activities and homework are reversed, with students gaining first exposure to new material through videos or other resources outside of class time. This allows class time to be used for exploring topics in more depth and applying concepts through hands-on activities. The document provides examples of online resources that can be used to create flipped classroom content and suggests activities students can do outside of class to prepare for in-class work.
