Stop Asking Teachers to Chase the Discovery Dragon

The phrase “chasing the dragon” refers to the classic cycle of addiction. People keep chasing the dragon not because it’s working, but because they’re convinced the payoff will eventually come — if only they keep trying. (I’ll spare you a digression into my history with the game of golf.) Teachers are told to chase the … Continue reading Stop Asking Teachers to Chase the Discovery Dragon

Why Direct Instruction Remains Relevant Today

Direct Instruction—note the capital D and I—is the OG of explicit teaching. Back in the mid-1960s, folks at the University of Illinois and later at Oregon arrived at a simple but essential insight: better teaching leads to better learning. As Siegfried Engelmann liked to point out, if students didn’t learn it, the teaching didn’t happen. … Continue reading Why Direct Instruction Remains Relevant Today

Science of Learning Jargon And Element Interactivity

A possible barrier to the science of learning movement is that there are potentially a lot of research terms and definitions that need to be learned in order to communicate clearly with one another. On the one hand, the pursuit of a shared language among educators is worthwhile. If when you say productive struggle, I … Continue reading Science of Learning Jargon And Element Interactivity

The Escape Room Problem With Collaborative Cognitive Load Theory

Every so often, someone who knows I’m a fan of Cognitive Load Theory brings up its collaborative offshoot, Collaborative Cognitive Load Theory (see Open Access Article here), and wonders what I think.

Education is a Pendulum of Fads

If you’ve ever wondered why education seems doomed to repeat itself—why each decade brings another “new” idea that’s really just an old one with different branding—you’ll appreciate what Doug Carnine has to say. Carnine, a longtime advocate for evidence-based teaching (and a guest on a very popular episode of Progressively Incorrect), argues that our field … Continue reading Education is a Pendulum of Fads

What’s With the Names?

Every once in a while, I get asked some version of: “Zach, what’s with your titles?” Progressively Incorrect? Education Rickshaw? Just Tell Them? Let me take a moment to unpack the chaotic branding I’ve cobbled together over the years— each name basically a timestamp from a different era of my teaching life, rooted in references … Continue reading What’s With the Names?
