Believe it or not, but I did a fairly detailed study of public schools. I spent nearly two waking years over more than a decade auditing and participating in 50+ classes at levels from K to pre-university, across ten or more schools.

Even if my experiences are uncommon they're enough for me to recognize errors and overly broad assumptions in other people's work.
