>I’m not sure that we ever figured out teaching methodologies that work for all children.

This is a fundamental problem with all learning: it's difficult to get entire group to do something the same way with equal effectiveness... that being said, teaching methods are evolving and it's really on the school system to embrace those changes. My kids are young, and their school teaches math with the Singapore Math system and literacy with the UFLI program. They have both been highly effective.

Their class sizes are also 12:1 students:teacher ratio, and 6:1 in Pre-K/Kindergarten. So that's also probably important.

Absolutely.
