In the eighties, the HT of my comp went a bit off the rails and decided we would only do traditional learning in the mornings, and that we would start up an 'afternoon activities' programme after lunch. At the time, we thought it was pretty cool, because we could go sailing (on a reservoir), kayaking, swimming, play chess, do d.ofe., head out to adventure club and build rafts on the river, learn one of three or four languages that weren't on the curriculum (we had French, German, and briefly Russian as options on the curriculum), art clubs of different varieties, mates club etc etc, athletics club, cross country, different team games (in additional to the pe that was timetabled).
Until much later, I hadn't realized quite how 'different' this guy was. Or the opportunities he opened up for the bog standard kids in bog standard town on low income. My mum was a cleaner, and I got to go sailing twice a week, and race for the school in regattas.
He had a breakdown after a couple of years and was asked to leave, and the whole thing was diluted. But v progressive.
Wouldn't happen now.
