The irony she brings up has been something that's been bothering me for quite some time--namely, why do institutions that study how we learn not apply those learnings? Granted, large institutions usually do go with the path of least resistance, but surely there must be some trickle down effect? It would be ridiculous in any other discipline to not use newly discovered/developed and provably more efficient processes than follow tradition (there are exceptions, of course), why is it not the case with education?
