Interesting set of exchanges between Dan Myer and others on the relative merits of direct instructions, worked examples, inquiry learning, and some blend of the three. Towards the end there is an discussion about adaptive software.
Argument that MOOCs can be used as part of a 'flipped' and/or blended approach for students in (what they call in the US) community colleges. This quote suggests Bill has lecture-based MOOCs in mind "Of course it's quite controversial, what software can take over, but once you get a great pool of lectures out there that incorporate problem solving and drill practice, this frees up time" for more-personalized instruction in the classroom, Mr. Gates said. With more work done at home and online, students could spend less time on campuses, freeing up classroom space to accommodate more students, he said. That approach works well, he added, with remedial mathematics, where only about 10 percent of students who start courses end up getting two-year degrees within three years."
