Thanks, Professor Becker, for posting that exciting story by Amanda Ripley in TIME (pasted for reference below my signature. I was in particular drawn to: > > In every country, education changes so slowly > that it can be hard to detect progress. But what > happened next was truly different.

Education can change - and (given the enthusiastic participation of its primary stakeholders, the students - it can change very speedily indeed! And: if education can change, so can a lot of other societal systems...
