David's research field is physics education research, and he uses the ISLE philosophy by Etkina and Van Heuvelen in his physics classroom.
His research follows two strands: 1. He is interested in embodied cognition and uses this general approach to understand how physics students understand language and how they understand physics equations. 2. He is interested in engineering the learning environment so that physics students can teach themselves, acquire scientific abilities, and develop positive attitudes towards physics.
