Hank Ryan, then a new physics teacher at Minnesota’s Mounds View High School, simply hated chapter test reviews. “These chapter reviews took exciting concepts and just flattened them,” Hank says. “I wanted kids to understand that physics concepts are a real live part of their world—and that they dictate how the world behaves. I wanted to show them that physics can be experienced. That it’s something they can see with their eyes, feel with their hands—and something they could learn to predict.” Read more about the history and development of practicums in physics.
