A flipped classroom is one where students learn content at home through videos or readings and use class time for discussions and activities. This allows students to work at their own pace and get help from teachers and peers. Some benefits are that it accommodates different learning styles and allows students to learn more deeply. However, it requires more work from teachers in preparing materials and relies on students completing work at home. The document also discusses ways to implement flipped classrooms and considerations around student and teacher preparation and access to technology resources.
