This document discusses flipped classrooms as an innovative teaching methodology. It defines flipped classrooms as reversing traditional learning by delivering instructional content online outside of class, and moving activities like homework into the classroom. It describes six types of flipped classrooms: traditional, debate-oriented, demonstration-based, group-based, virtual, and double flipped. Each type is explained with examples of how instructional content is delivered before class and how class time is used for activities, practice, and collaboration among students. The conclusion states that flipped classrooms add value to face-to-face interaction and student engagement by allowing students to explore content and test skills before receiving guidance from instructors in class.
