"We try to teach teachers to put the student in charge of their learning," said Higgins, who moved to the U.S. from Britain in 2001 and now lives in Michigan. "We try to empower. Sometimes, you get a pushback for that because if you're empowered, suddenly you're responsible and accountable. But once they get the hang of that, it's a quicker way to learn. It kind of puts kids on the fast track. "
