I’m not a fan of what the education overlords call “differentiation”, but you still have to adjust to what the students are telling you. This breakout was all about the perils and pitfalls of differentiation, and how the only kind that works is one based on real-time adaptation.

"a movement rooted in social justice but one which takes responsibility for outcomes." Read that again please. "but one which takes responsbility for outcomes." See the difference?
The one thing I’d want everyone to know about Direct Instruction is that the methods, materials and routines are far less important than the underlying drive behind it: the unswerving belief that EVERY child can achieve, regardless of circumstance. DI is based on a deeply held conviction that if a child didn’t learn, it was because the teacher (or curriculum) didn’t teach them properly. In that sense, it is a movement rooted in social justice but one which takes responsibility for outcomes. In the 60s and 70s, there was a view in the education academic establishment that formal academic work was premature for 4-year-olds, and doubly so for poor ones; so what they needed was enrichment and play. Worse still, in the early 70s, some academics described DI as a racist enterprise*. Engelmann's own memoir notes that he and Bereiter were called “Nazis” and “kid-haters.” Despite this, Engelmann taught disadvantaged 4 year olds to factor and to solve simultaneous equations, and filmed it. Bereiter and Engelmann’s argument, set out in ‘Teaching Disadvantaged Children in the Preschool’, was that the disadvantaged child was not “behind” in some general developmental sense but behind in specific, teachable things, that all kids could learn with the right scope and sequence. The preschool they opened in the mid 60s ran for two hours a day, with three twenty-minute lessons in language, arithmetic and reading, taught to small groups by a teacher following a specific DI sequence. Those kids made huge gains which faded when they went to normal public schools. DI has its limitations like everything but the drive behind it is sincere. As #SoldAStory season 2 will show, it has been portrayed as something very different to what it actually is and the animating principles behind it. *Baratz and Baratz, ‘Early childhood intervention: the social science base of institutional racism.’

I’m not interested in hearing about your “passion for social justice and equity” if you promote inquiry-based learning over explicit instruction, believe ambiguous, skills-based education is superior to knowledge-rich, content-focused education, and advocate for restorative circles instead of clear, consistent discipline. You can’t say you’re passionate about social justice and equity while supporting practices that perpetuate inequitable access to knowledge and policies that harm students who are victims of verbal and physical abuse at the hands of their peers.

If you’ve listened to Season 2 of Sold a Story, you’ll recognize this 1966 video of Siegfried Engelman demonstrating his direct instruction approach to math with children who had been written off already by the education system. His theory that if the kids aren’t learning, the teacher hasn’t done their job is key. youtu.be/mI5rRALTuyg?is=R6Gl… via @YouTube

One of the most eye-opening sections of Season 2 of "Sold a Story" is the deep dive @ehanford and her colleagues made into the archives of Project Follow Through unpacking how its findings about Direct Instruction were challenged and massaged. My review here: thenext30years.substack.com/…

I'm super excited about this week's episode! How do we make math teaching clear and more effective for every student? I talk with @Kris_Boulton about designing better lessons by considering the four types of mathematical knowledge, and how we can ensure success for all students. 🎙️ Coming October 16. Don't miss it!

We worry that putting struggling students in a separate class will embarrass them. So instead, we leave them in a room where everyone else understands the lesson and they don’t. And we do this day after day, year after year. It’s no wonder they feel like they don’t belong—they don’t.

A special ed accommodation that gets a kid through graduation without learning to read has accommodated graduation rates more than it has the student.

Minimally guided instruction doesn't work with AI tutors either. One thing we are finding out is that Socratic questioning models are very frustrating for students when they withhold the explicit guidance novice learners actually need. arxiv.org/abs/2609.29995

When a procedure becomes a routine it focuses student working memory on learning. When it becomes a visible predictable norm it motivates and shapes positive behavior.

If your school’s behaviour management policy requires you to a) Be a child psychologist b) Stop everything to focus constantly on one child out of thirty c) Be telepathically intuitive and magically persuasive d) Accept rude or unsafe behaviour e) Stop and think hard about the exact, complex next step… Then it’s not a behaviour policy, but a misbehaviour policy, because it creates an environment where misbehaviour is more likely. It’s also a quit-switch for staff who are human beings, not sorcerers.

Ever so often, someone opines on here that all we need is teachers who work hard and care. This the same kind of claim as "students would learn more if they were more motivated." It’s a nothingburger - useless. Variables we can control: pedagogy, curriculum, and systems.

Somewhere E.D. Hirsch Jr. says, “I told you so.”
Natalie Wexler argues social studies boosts literacy: more social studies time raises reading scores (unlike extra reading time), especially for low-income kids, by building knowledge/vocabulary. Louisiana, Massachusetts, Kentucky created state curricula; Delaware pilots "Literacy for We the People," pairing civics/history with writing/speaking skills via simulated hearings. nataliewexler.substack.com/p…

I don’t think you need to have even been a teacher to know that you can’t just fix up a deep learning problem with a quick dose of “differentiation.” A student dealing with a history of persistent failure will need a program that goes back to the beginning and builds from there.
