The SciPlay app is essentially an annotated video: Using an iPad, you film motion–running, jumping, swinging, sliding, throwing a ball, etc.–and the app visualizes the basic science at work, pinpointing moments and levels of velocity, acceleration, energy, and force. Through manually tracing the arc of motion of the ball or person, or by using sensor data from the iPod attached to a ball or a kid’s belt, it superimposes the force diagrams that make up the backbone of any classroom physics…
A study of teacher education at a New York City institution shows promising results, suggesting ways that teachers can be prepared to teach for deeper learning.
Interleaving is about retrieval practice, having students regularly revisit recently acquired knowledge, but not in the order it was presented or learned.
