The document discusses the flipped classroom model of education. In a flipped classroom, instructional content is delivered to students outside of class, often through online videos, freeing up class time for more active and collaborative learning activities. During class, teachers guide students through hands-on problem solving, discussions, experiments and other engaging lessons, allowing for more personalized attention. The flipped classroom shifts the focus from a teacher-centered model to a learner-centered approach that emphasizes higher-order thinking skills.
