Don’t get fooled by observational correlations

Gabriel Power writes: Here’s something a little different: clever classrooms, according to which physical characteristics of classrooms cause greater learning. And the effects are large! Moving from the worst to the best design implies a gain of 67% of one year’s worth of learning! Aside from the dubiously large effect size, it looks like the […]

Columbia Data Science Institute art contest

This is a great idea! Unfortunately, only students at Columbia can submit. I encourage other institutions to do such contests too. We did something similar at Columbia, maybe 10 or 15 years ago? It went well, we just didn’t have the energy to do it again every year, as we’d initially planned. So I’m very […]

John Hattie’s “Visible Learning”: How much should we trust this influential review of education research?

Dan Kumprey, a math teacher at Lake Oswego High School, Oregon, writes: Have you considered taking a look at the book Visible Learning by John Hattie? It seems to be permeating and informing reform in our K-12 schools nationwide. Districts are spending a lot of money sending their staffs to conferences by Solution Tree to […]

The competing narratives of scientific revolution

Back when we were reading Karl Popper’s Logic of Scientific Discovery and Thomas Kuhn’s Structure of Scientific Revolutions, who would’ve thought that we’d be living through a scientific revolution ourselves? Scientific revolutions occur on all scales, but here let’s talk about some of the biggies: 1850-1950: Darwinian revolution in biology, changed how we think about […]

Amelia, it was just a false alarm

Nah, jet fuel can’t melt steel beams. I’ve watched enough conspiracy documentaries – Camp Cope Some ideas persist long after the mounting evidence against them becomes overwhelming. Some of these things are kooky but probably harmless (try as I might, I do not care about ESP etc), whereas some are deeply damaging (I’m looking at you “vaccines […]
