Using Cognitive Science to Improve K12 Education

I will be honest, I’ve always been a crammer. I got through high school and college by doing as little as I could to get through the classes that didn’t really matter. That mostly meant quickly memorizing everything I could in the couple days before a test. …


Every year, Americans spend more on lotteries than they do on music, movies, sporting events, and books combined. Despite all the odds, it’s seen by many as a viable form of savings.

As a math teacher, I don’t know how to process that. The expected return is basically zero yet…


How a focus on easily measured success may miss the point

In 2015 I co-founded a nonprofit to combat food insecurity. Since then we’ve grown into a full 501c 3, we’ve fed a lot of food insecure people within our community, and we’ve figured out ways to sustainably build food pharmacies and food cooperatives. …


Why Keeping Teachers in Schools for the Long-term is so Important

As a teacher I’m told a lot of stories about how education works and how we are going to fix it. We tell the stories because they give us easy-to-understand enemies along with optimistic explanations of our problems. But these stories are not often based in evidence. And when they…


Or different ways to help students be more rational

This is an idea that I frequently talk about to students and colleagues that I stole from Tyler Cowen who may have stole it from someone else. It goes along with a lot of how I’ve been thinking about improving rationality through culture rather than education. In other words, it’s…


We have built our entire education system on standardized testing. It would seem like we should have a lot of the details for testing figured out. However (and without going into too much of the messy details) there’s a lot we just don’t quite understand. in particular I can’t find…


Prices have gone up 200% in 20 years, we need to find a new way forward
