"Gaining a broad knowledge of words, and therefore also a knowledge of the things to which words refer, must be among the most practical and significant educational goals in our time."

Giving novices problems they lack the knowledge to solve makes little sense. Ausubel said this in 1968 and it still holds true.
"If I have to reduce all educational psychology to just one principle, I would say this: the most important single factor influencing learning is what the learner already knows. Ascertain this and teach [the learner] accordingly."

I used to teach science where I’d facilitate an experiment, stop it on occasion to explicitly teach, and then have them dive back in. While that was better than discovery learning, it was way worse than pre-teaching the science content. This is true of other subjects as well.

That's why I think opportunity cost is the single most important idea in school improvement. Every hour our teachers—and our students—spend on one thing is an hour they don't have to spend on something else. And this matters most of all for students who find learning hardest...

At workshops we often talk about having “back pocket phrases” to use when a student answers incorrectly but you want to build a culture of error. That is you want to say: “that was wrong but it’s fine because your answer is still really valuable!”
Today Catherine Garland shared one of my favorite all time examples: “I was hoping to hear that mistake.”

And this is what happens when we don’t use standardised, externally assessed, anonymous examination as much as possible. The extrinsic motivators to game the system are overwhelming, and the grades become meaningless.

The teacher who gives a failing grade has to explain it to the student, the parents, and the principal.
The teacher who gives everyone an A has a quiet weekend.
Still confused about how grade inflation has gotten so bad?

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.

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.

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:

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!

What is Direct Instruction?
Sam Altarac retweeted
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.
