> I'd push back a little on the framing that engagement and learning are separate things (anyone on our team will tell you this is a drum I have beaten for years). A disengaged child learns nothing, no matter how good the pedagogy is.

Engagement and learning are definitely separate things; you're right that engagement is required, but that's only part of it. This is a classic case of 'necessary but not sufficient'.

A disengaged child is not learning; an engaged child might be.
