In this interview, Bernie describes his design process, which combines constructivism with an artistic approach to teaching science. You will hear him contrast his materials-informed approach with that of Grant Wiggins' backward design. Listen to the case he makes for getting user feedback when designing a new learning system-- the Boston Children's Museum is a great place to see firsthand how users (kids) react to prototypes of a new display. Notice the design criteria that Bernie mentions as he describes his working at engaging young learners. How could a similar approach be used when you design a lesson or adapt a piece of curriculum to your classes?
