I think there was an earlier Gates Foundation project to fix education which had a fascinating result.
They pumped a fair bit of money into a handful of schools, gave them extra resources for various things, got them doing some stuff differently or whatever. Scores went up some. Then they stopped the funding. The schools kept trying to do whatever it was, because it had seemingly worked. Scores went back down.
This seems to have been cast as ‘oh that didn’t work’, but I think it actually showed that more resources, perhaps of almost any kind, helps. The teachers at the school will figure out how to get a benefit from almost any actual valuable (and therefore non-free) resource they are given.
Essentially we know how to make schools better. We have dozens, probably hundreds or even thousands of things we could do that we know work. Problem is these things all cost money. And that isn’t what is wanted. What is desired is an answer that is free.
So instead of just spending more and getting better results we spend in dribs and drabs trying out various schemes to get something for nothing, very few of which work at all and none of which are a big deal.
