Peter Gray presented some data about the correlation between anxiety in children and the school calendar in an article in his Freedom to Learn series.
“Kids are people,” Gray writes, “and they respond just as adults do to micromanagement, to severe restrictions on their freedom, and to constant, unsolicited evaluation.”
I thought a chart might make it easier to digest, so I put this one together via Google Sheets.
This looks only at data from the Hartford Connecticut Children’s Mental Center. I’d love to see this on a national scale, for specific cities and regions, and–though I can’t imagine how the data would be collected–from school to school (including homeschoolers and unschoolers).
