I think there is a bit of merit to this - part of the problem of schools (which i've read about off and on for years) is the expectation that students sit there and absorb lectures without any actual interaction with the information they are supposedly learning. I find this would be a decent bit of solution if it were used in conjunction with other changes. But considering in some places they make a fairly grand issue about whether or not students should learn cursive writing (Indiana has had this) and there are people that think education should go back to "reading, writing, and 'rithmatic", I doubt schools are going to consider this approach, let alone others that try to solve a number of issues with people dropping out of high school.
