Or, maybe, K12 education is about subject-based teaching and universities are the place to step free of that? Dorothy Sayers wonderful essay, The Lost Tools of Learning, suggests something like that. I say something like that because organizing curriculum by chronological age, rather that developmental age, is a problematic assumption.
This has big implications for well-established programs such as the International Baccalaureate program. Maybe we will see it’s excellent inquiry-based approach in Primary Years Pr0gram extend all the way up to its Diploma Program?
