Physics Alive

Physics Alive is the podcast where host, Brad Moser, Ph.D., sparks new life into the physics classroom. Each episode supports and shares the many forward-thinking developments that have come from physics education research and inspiring educators. Brad speaks with teachers who employ innovative and active learning styles, researchers on the frontiers of physics education, catalysts for change on important social issues in the STEM community, and students who want the most out of their education.


episode 29: Fluency Bias and Deliberate Practice with Louis Deslauriers

This is part 2 of an interview with Louis Deslauriers, the Director of Science Teaching and Learning and Senior Preceptor in Physics at Harvard University. We discuss two recent publications from his research group. In the first, he finds that students can actually feel like they are learning more while passively listening to a polished lecture than engaging in active learning. We’ll talk about that finding and what that means. In the second, we dive into his latest work on deliberate practice, and how we might take the gains from active learning in the classroom and boost them up even more by transforming homework.
