What’s Podject-based Learning?

When you combine podcasts and projects together you get Podjects! Inspired by project-based learning, TinkerClass’ Listen, Wonder, Tinker, and Make phases keep kids inspired and energized as they work individually or as a group. Research shows that two-thirds of students were more engaged in TinkerClass compared to other new activities. But, why do we Listen, Wonder, Tinker, and Make?

When science education is centered on phenomena, the focus shifts from learning about a topic to figuring out why or how something happens.


Cognitive researchers report that children learn best when they are “active and engaged in learning that is meaningful, socially interactive, iterative and joyful.”
