Super! ... "Peter Norvig: The 100,000-student classroom" (6 minute video) ...
adding to 'Proof of Educational Information Technologies' Effectiveness' -
at World University and School :)
In addition, WUaS is planning to use surveys to gauge ENJOYMENT/Happiness/Flourishing,
plus so many related aspects of learning in MIT OCW-centric
"The College at WUaS" -
and potentially in all 3000-8000 languages and 200 countries ...
which will become a fascinating and ginormous database,
about not only enjoyment in learning,
but via the internet.
