The idea of “Flipping the Classroom," using class time to work through homework, has been around for awhile. The problem has been finding appropriate material to use as the lesson for the students at home. I worked with high school math teacher John Schnatterly to create a series of videos about trigonometry that he could assign as homework to his classes. The students would watch the videos at home and try to solve the challenge question posed to them. The next day in class Mr. Schnatterly would work with them through any issues they had in solving the problem. The results were better classroom attention and a deeper understanding of the concepts behind the problem.
