The document discusses the flipped classroom model pioneered by Aaron Sams and Jonathan Bergmann. In a flipped classroom, students watch video lectures at home and use class time for hands-on work, discussions, and problem-solving with teacher guidance. Key aspects covered include the benefits of flipping such as increasing interaction and differentiation. Implementation considerations like video length and tools for hosting and creating videos are also outlined. The document advocates for using class time for enrichment, practice, and building relationships between students and teachers.
