I am one of those who believe that this is the future of education. It won’t be an easy transition and I have more than a little respect for the skeptic who says that it’s like putting a new program on an old computer. However, this is going to be a long movement from one-size-fits-all to more customized learning experiences.
This is not to say that you can send (young) learners out to find their own way. That has been tried and tried again with less than optimistic results.
This move will have significant push-back in the US, not when promoting young learners, but rather when retaining older learners. The pressure for age-based promotion could ruin this approach. When you taint performance-based promotion the whole system falls apart.
