Taking stock, it would appear that Annaliese et al have done a pretty poor job of telling Michael how things are going stateside (or else he hasn't listened to them).
It looks like the Hirsch Core Knowledge schools are using a knowledge-based curriculum, supported by the CCSS, much of which is skills based.
This doesn't fit in with Gove's sentiments about teaching 'skills'.
I feel now, that I should be more sympathetic of Pimlico going down the Core Knowledge route, as it seems to embrace both knowledge and skills.
Has Gove chosen to misinterpret the Massachusetts model in favour of nationalism?
