Under the model, teachers make eight- to 10-minute videos of their lessons using laptops, often simply filming the whiteboard as the teacher makes notations and recording their voice as they explain the concept. The videos are uploaded onto a teacher or school website, or even YouTube, where they can be accessed by students on computers or smartphones as homework.

For pupils lacking easy access to the Internet, teachers copy videos onto DVDs or flash drives. Kids with no home device watch the video on school computers.

Class time is then devoted to practical applications of the lesson -- often more creative exercises designed to engage students and deepen their understanding. On a recent afternoon, Kirch's students stood in pairs with one student forming a cone shape with her hands and the other angling an arm so the "cone" was cut into different sections.

"It's a huge transformation," said Kirch, who has been taking this approach for two years. "It's a student-focused classroom where the responsibility for learning has flipped from me to the students."

I love this. It reminds me of the fictional schools in Michael Flynn's "Firestar" (although in that novel, the students dedicated two hours at school at the end of the day to finish homework). Via Teachers flip for 'flipped learning' class model - Yahoo! News.
