My friend and colleague Zak Slayback has had a wonderful series of blog posts about education, schooling, testing, unschooling, and many other fascinating and important topics in that area. I cannot recommend them enough.
Zak is continuing to churn out some great stuff on these topics, so I encourage you to frequent his blog. It’s been very interesting for me to see someone a decade my younger, with no kids of his own, and who by all measures was the apex of schooling success come to the same conclusions I have reached about schooling and childhood. There is something very exciting about the synchronicity of someone else discovering similar books and ideas as you do the same, independent of each other.
