The document discusses the flipped classroom model, where teachers create instructional videos for students to watch outside of class, freeing up more class time for interactive learning and student-centered activities. It notes that the flipped classroom was pioneered by Aaron Sams and Jonathan Bergmann in order to maximize in-class learning through previewing content, deeper discussion, individualized instruction, and student work. The document encourages teachers to think about how to best use face-to-face time and what classroom activities could be "flipped" to videos for homework.
