Many have wanted to replicate DARPA’s success in solving public problems outside of defense but few understand the secret to the agency’s success catalyzing innovations that improve the world.
The secret: a laser focus on “Pasteur’s quadrant.”

Kids learn because they have access to good instruction, not programs.
There are lots of ways to deliver good instruction (reg classroom, tutors, summer)—just like there are lots of ways to take your allergy meds (capsule, tablet, oral).
Bad instruction won’t produce results no matter how you take it.
We don’t need complicated theories to explain the decline of math skills.
It’s actually pretty simple: kids can’t learn without effective instruction.
America's kids can't do math anymore.
The avg 8th grader’s math skills, which rose steadily from 1990 to 2013, have plunged to 1970s levels.
Combo of phones, social media, pandemic, and declining education standards, have gutted American numeracy.

Why don’t kids have effective instruction? Because the most powerful voices in education have embraced pseudoscience.
When the scientific establishment fails to self-police, ideas like “fluency without fear” gain currency.

If Democrats want to have credibility w/everyday Americans, they need to drop the Chicken Little act.
The erosion of educational opportunity began under their watch. It won’t be addressed by defending the status quo.
Everyone is treating this like a big deal. IMO it's not...they will move some boxes (and people) around, and, if a Democrat wins in 2028, it will be swiftly undone.

I will never understand why some people believe that *more* dopamine is the solution to dopamine addiction.
Schools were never built to compete with dopamine on demand. In my latest for @educationgadfly, I look at what happens when classrooms are forced to battle the attention economy—and why it’s a losing fight.
Here's why you should be talking about it:
Special education affects everyone–district admins, state legislators, regular & special education teachers, parents, and kids inside & outside of special education.
Rates of special education identification have nearly doubled
The story in education that no one's talking about
h/t @aejochim
“Zig” Englemann famously declared that if the student didn’t learn, the teacher didn’t teach.”
Behavior, like academics, is a skill: what students learn depends on the practices that adults use.
Let’s fix those practices before we start sending kids to the impound lot.
When I talked to the Dean of Students about a group of boys lewd behavior directed to my 12 yr old daughter, he shrugged his shoulders, saying “kids will be kids.”
A generation of kids & teachers are suffering because of our failure to expect better.
“High-quality instructional materials” does NOT “research based.”
"In other words, the way lessons and assessments are written may force students to expend so much energy figuring out what the question is asking that they don’t have enough mental bandwidth left to focus on the math itself." bit.ly/3HIakM9
Advocates overestimate the value of choice & and underestimate its costs.
My Kroger's has roughly 170 options for pasta sauce. 210 sparkling water SKUs. 40 syrups. 100 sizes & brands of bottled water. For what? It's choice overload and the logistics of all this raises prices.
Aldi is going to crush it in the US. The concept of smaller footprint, limited selection, simpler display, and mostly private label to achieve a lower price point is spot on.
The endless rows and selection used to amaze the Soviets. But it's been taken too far, creating choice paralysis, wasting time, and driving up costs. Just wish Aldi was publicly traded.
📢 The high-quality instructional materials movement has failed to provide teachers what they need to support student success with grade level instruction.
Last year, I interviewed a kinder teaching using @ELeducation who turned to YouTube to scaffold unfamiliar vocabulary.
Why aren’t more people in the HQIM space talking about this issue?
Why does the field continue to pretend that “quality” is synonymous w/grade level instruction even though access to that instruction depends on remediation?

Remediation of foundational math skills is essential but “going back” to the beginning is not the best way to fill gaps.
Remediation must focus on the fulcrum points-topics that play outsized roles in mastery (e.g., fractions).
Have a friend who’s an expert in the science of learning. Once, we got to talking about math. He said the lowest hanging fruit is to send every kid back to the stage of math they’re not 100% fluent in.
For most kids, that’s something like 3rd or 4th grade. Then they should work their way up, step-by-step, and only graduate to the next level once they have mastery of the level before. And now with learning apps, they can speed-run the catch-up process.
The research is clear. It’s the social stigma of going back that holds kids back. Kids don’t want to be made-fun of, and no parent of an 8th grader wants to send their kids back to 3rd grade math, no matter how effective it may be.
We know how to fix the problem. We’re just afraid of the social repercussions. Many things work like this.
Hive mind:
What are the problems in popular math programs like i-Ready, Zearn, etc?
What would you want to see in an effective tech-based math intervention program?

We could learn a lot about how to design effective schools by talking to moms.
Moms know:
✅ Children don’t always want to do what they need to do
✅ Cooperation depends on both consequences and relationships
✅ If you want children to behave, you need to teach them
👀
People on the front lines of k12 education have stories to share about the effectiveness of popular k12 reforms.
What if we actually listened to them?
US Educators: which school cell phone policies actually work, and which do not? There is v limited data on this question. Please help by taking this five-minute survey on your experiences. phonesinfocus.org/
👏👏👏
It’s arguably worse than @MrZachG suggests.
Consider: we recently invested billions on teacher eval systems that treated effectiveness as a function of individual effort, not the tools & systems that support good instruction.
