“It’s designed to get people to a ‘standard of knowing.’ … I’m suggesting that we need to replace the measurable ‘content’ for the non-counting noun ‘caring’. Give me a kid who’s forgotten 95% of the content they were measured in during K-12 and I will match that with almost every adult i know. Give me a kid who cares about learning… well… then i can help them do just about anything.”

If you have a second, Dave, check out Matthew Lieberman’s book Social, particularly Ch.12 where he discusses education. He echoes your point on page p.282 where he writes:

“We spend more then 20,000 hours in classrooms before graduating from high school, and research suggests that of the things we learn in school, we retain little more than half of the knowledge just three months after initially learning it, and significantly less than half of that knowledge is accessible to us a few years later.”

Brutal. Yet we continue to double down.
