Dr. Tammy VanDeGrift and Niki Schulz both know what it's like to teach a classroom of engineering students and wonder how much actually sinks in with students. Now there's a way to find out. Both have been experimenting with recording class material on video and asking students to watch before coming to class. As a result, class time can be used for small group collaborative exercises in problem solving. Students get to interact with each other and Schulz and VanDeGrift get to find out how well students are grasping new concepts and putting them into practice.
