Flipped learning is a pedagogical approach where direct instruction moves from group learning spaces to individual learning spaces. Students learn new concepts through videos or readings at home, then apply that knowledge in class under an educator's guidance. The four pillars of flipped learning are a flexible environment where students can choose when and where to learn, a learner-centered culture where class time is used to explore topics in depth through student participation and self-evaluation, intentional content to maximize in-class time, and professional educators who observe students closely and provide relevant feedback while tolerating some controlled chaos in the classroom.
