There are lots of apps, but determining which ones can be most productive in the classroom can be a daunting task. Michael Strange helped participants focus on apps for physics and general classroom management and then we began the task of “re-engineering” activities to be aligned with NGSS with a focus on the elementary STEM classroom. Cathy Barthelemy and Katya Denisova helped participants see physics through the eyes of elementary students and participants engaged in a learning cycle on friction for “Fred on a Sled”. Our partners from the Perimeter Institute wrapped up the day with challenges of teaching wave particle duality!
