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?

Are Teachers Change Agents?

Today I read Robert Pondiscio’s piece, Public Schools Are Molds Not Platforms, and he’s right about something fundamental: public schools are not platforms for personal expression or ideological performance. They are civic institutions with a public mandate. A teacher in a classroom is not a freelance partisan activist — they are a public servant with … Continue reading Are Teachers Change Agents?

How to Make Coaching Work — Every Time, With Every Teacher

When I first started teaching, I was fortunate. I got paired with two people who made a real difference in my development: a math coach and my mentor teacher. Neither had a formal coaching framework. They didn’t have an evidence-informed approach or shared language for what “good” looked like. Still, they helped me grow - … Continue reading How to Make Coaching Work — Every Time, With Every Teacher

Explicit and Direct Instruction Systematically Manages Cognitive Load—It’s Not Just Lecturing

I recently presented a two-part series for an organization called POPEY (the Provincial Outreach Program for the Early Years). A B.C.-based organization, they support K–3 educators with research-based literacy resources, professional learning, and classroom tools. In the two FREE sessions, I challenged myths about explicit and Direct Instruction. Far from rote lecturing, explicit and Direct … Continue reading Explicit and Direct Instruction Systematically Manages Cognitive Load—It’s Not Just Lecturing

Direct Instruction Embodies the Science of Learning

In one of my more popular posts, I argued that we need to do better than just nod politely at Direct Instruction (DI). Cognitive Load Theory is honored through DI’s ruthless efficiency: every word is deliberate, every example intentional, every new piece of content layered step by step to keep working memory clear and focused. … Continue reading Direct Instruction Embodies the Science of Learning
