At Sudbury schools, like anything else, the Zone of Proximal Development is self-controlling. Students are constantly pushing themselves into their “i+1,” trying to get that little bit better at
their current activity. And here, our age-mixing especially helps. It’s easy to find someone a year or two older, someone who’s just that little bit better at reading or just that little bit better at
throwing a ball, or whatever other skill our student is trying to master at the time.
There’s no need to engineer or manipulate our kids into the Zone of Proximal Development. They’re constantly there.
