The document provides guidance on designing flipped classroom lessons using the IPP model. It discusses:
1. Planning lessons by defining objectives, skills, content, and activities to be done before, during and after class.
2. Implementing the plan through pre-class tasks, introducing the topic in class, activities for self-assessment outside class, and peer/teacher assessment in class.
3. Challenges of the flipped methodology include changing teacher and student roles, operationalizing it for large classes, and overcoming student resistance to a more active learning approach. Careful planning and explanation of objectives is advised.
