Helping your kid with his or her homework may not always be easy. After all, it’s been years since you’ve opened a calculus textbook. Teachers in the Greater Chicago area and across Illinois are experimenting with a new teaching method that flips homework on its head. Instead of asking students to do high level thinking for homework, teachers assign video lectures for homework and then work on problems and projects at school. WBEZ producer Becky Vevea visited a school downstate that is flipping instruction to see how it works, and she explains what she learned. (Photo: Flickr/lauracoughlin)
