are providing lots of fodder for research into educational techniques, which will aid this improvement. Back to the high cost of education. MOOCs offer the most scope for change in under-graduate education. And that's where the massive cost hurts individuals the most. Undergrad programs tend to have the highest number of lecture-based informational survey courses, and MOOCs are ideally suited to replace those. And improve on them. They may not all be free, but they will be available at half or less the cost of traditional university courses. And that can have an enormous impact on the educational system. It is already starting to show that potential.
