Bloom's 2 sigma study is one of the most poorly designed and misleading papers in all education research. It's based on a couple of hundred kids who got 7 hours of intro lessons on cartography. Their progress was measured with unstandardised assessments. It cannot bear any of the enormous weight that people place on it, and it baffles me that 40 years on people are talking about recreating it like it is some kind of holy grail. We will know education is a mature science when people stop talking about Bloom's 2 sigma study! substack.nomoremarking.com/p/blooms-famou…
