Of course, free education resources like Khan Academy and MIT's aren't displacing traditional schooling yet. But it's easy to imagine how the growing availability of free world-class educational resources will revolutionize American education. For example, given the increased popularity of credit-by-examination programs like Advanced Placement or College-Level Examination Program tests, motivated self-learners now have an opportunity to use online instruction to complete their education at their own pace.
For decades, policymakers have struggled and spent untold billions trying to ensure that all students have access to a world-class education. But solutions have proved elusive.
Thanks to innovators like Salmon Khan and forward-thinking schools like MIT, the answer may finally be here and at a price that's impossible to beat.
