Welcome to the show, everyone! I'm Renata Salas, and I am here with Colin Whitfield. And Colin, I want to start with a piece of writing that completely reframed how I think about the first five minutes of my class. Back in September of 2018, the cognitive scientist Pooja Agarwal wrote a piece for RetrievalPractice.org where she made this incredibly counterintuitive point: retrieval practice is a learning strategy, not an assessment strategy. Yes! It is a memory workout, not a mini-test. And that distinction is everything, isn't it? Because normally when teachers hear "retrieval," they think, "Oh, right, I need to quiz them on what we did yesterday to see if they read the chapter." But actual cognitive science tells us that the very act of *struggling* to pull information out of your brain is what actually cements the neural pathway. Exactly. And there's this brilliant, classroom-built tool that does this beautifully. It was designed by a history teacher in the UK named Kate Jones while she was teaching over in the United Arab Emirates. She called it the Retrieval Challenge Grid. And I love this because it didn't come from some high-level academic district office memo; it was built by a teacher in the trenches who needed a way to make review actually stick. And the structure she came up with is so elegant. It's essentially a matrix, often color-coded to represent time elapsed. So, you might have blue boxes for "last lesson," red boxes for "last week," and green boxes for "two weeks ago" or even the previous unit. Right. And by doing that, she solved the "recency bias" problem. Because normally, my warm-ups are just, "Hey, what did we write about yesterday?" And my kids do great on that because it's still sitting right in their working memory. But green boxes? Making them reach back two weeks? That forces them to dig. Well, you're hitting on three heavy hitters of cognitive load theory there: spacing, interleaving, and low-stakes retrieval, all packaged into one five-minute routine. Spacing, because we are widening the gap between learning and recall. Interleaving, because we are mixing up topics instead of practicing one skill block-style. It breaks that "illusion of learning" where students think they know it because they just saw it five minutes ago. Okay, so let's talk about what this actually looks like tomorrow morning in third period. You draw a simple three-by-three grid on the board, or maybe you hand out a half-sheet of paper. You give the students exactly five minutes. But here's the crucial rule: they can answer the boxes in any order they want. Ah, that is a clever bit of behavioral design. It lowers the barrier to entry. A student who freezes up on the hard stuff can start with the easy "yesterday" box, get a quick win, build some momentum, and then tackle the tougher, older stuff. Exactly! And to make it a little gamified without being high-pressure, you attach point values. So, one point for a blue box from yesterday, two points for a red box from last week, and three points for a green box from two weeks ago. My middle schoolers will do almost anything for imaginary points. It works for secondary school students in the UK too, trust me. And look at how flexible this is across subjects. In your seventh-grade ELA class, a green box might ask them to define "mood" from a story you read earlier in the month. But in an eleventh-grade chemistry class, I could use a green box to ask them to write out a balanced combustion equation from the previous unit. The cognitive mechanism is identical. And the payoff is massive. There was a fresh piece by Daniel Leonard in Edutopia, published on July 25, 2025, that highlighted some incredible data on this. He cited research showing that students who self-test using these mixed, spaced windows can score up to thirty-four percentage points higher on later assessments compared to those who just use traditional study methods. Thirty-four percent! That is the difference between a D and an A. Thirty-four percentage points. That is an astronomical effect size in educational research. We lose our minds over a five-point jump, and here we are looking at thirty-four, just from changing *how* we start the lesson. It really makes you wonder... are we dramatically underestimating how much of what we call "poor performance" is actually just a failure of long-term retrieval because we never built the retrieval muscle? Oof. That hits home. It makes me ask a really uncomfortable question: how many times have I walked out of a Friday lesson thinking, "They got it, they nailed the exit ticket!" only to realize on the unit test three weeks later that they didn't actually retain any of it? Yesterday's success is not tomorrow's retention. Precisely. If we aren't interrupting the forgetting curve, we are just building on sand. Well, that is our quick take for today. Try drawing a grid on your board tomorrow, and let us know how those green boxes go. I'm Renata Salas. And I'm Colin Whitfield. Happy retrieval practicing, everyone.
