I have watched states delay releasing test scores for months as they work to message results and hope no one is paying attention.

It's gratifying to see my recent immigration-raid research actually being used. wapo.st/42mWdTn

"Educators should also understand the limitations of research evidence. Rigorous impact evaluations...can only tell us what has worked someplace at some time—not what will work universally for educators facing specific challenges." - @tomdee.bsky.social www.edweek.org/leadership/o...

Why aren't practices based on research implemented in schools? @tomdee.bsky.social has insights, and ideas for change. www.edweek.org/leadership/o...

"...embrace opportunities for quick and meaningful wins. These are the common-sense education initiatives that share three critical features: evidentiary support, low financial costs, and scalability." - @tomdee.bsky.social www.edweek.org/leadership/o...

Just out in @edweek.org's #K12BigIdeas, I criticize the quality & connectedness of education research, policy, & practice and discuss what it would take to do better. www.edweek.org/leadership/o...

Have we given too much "credit" to the pandemic for learning losses? Almost 50% of the post-pandemic decline in achievement on 8th grade NAEP was to be expected (without the pandemic!), simply using the same rate of declining achievement that began unfolding starting in 2013!

The @nytimes.com spotlighted a new study from #EdWorkingPapers that examines the profound impact of immigration raids on attendance in California's Central Valley. Read the NYT article below.

Immigration raids in January and February increased absences by 22% in five school districts, according to a newly released Stanford study.

🚨New research from SIEPR Senior Fellow @tomdee.bsky.social finds that student absences rose amid intensified immigration enforcement, indicating lost learning opportunities. 👇 bit.ly/3I1vGDJ

I appreciate the work of @wtgrantfdn.bsky.social grantee @tomdee.bsky.social showing student attendance, already in crisis after COVID, is further disrupted by immigration raids www.nytimes.com/2025/06/16/u...

The current wave of federal immigration raids began in January with a “rogue” operation in California’s Central Valley. My new study finds these raids increased school absences by 22%—a leading indicator of the resulting family stress & lost learning opportunities👇 www.nytimes.com/2025/06/16/u...

I spoke with the NYT for this article. I'm unconvinced that the universal kindergarten redshirting of boys is a good idea... www.nytimes.com/2025/06/14/u...

Seen on the streets of Paris today. #EdPolicy is everywhere.

This provocative, data-infused essay by James Wyckoff — edworkingpapers.com/ai25-1197 — serves as a reminder that fully understanding the declines in student achievement requires us to look well before the COVID-19 pandemic.

Wow the latest episode of the @citizenstewart.bsky.social show nails it when it comes to the evidence on merit pay. It's hard to get it right (implementation details, supports, etc.), but it can move the needle on student achievement. But 👇 www.thebranchmedia.org/show/citizen...

I was so pleased to cross the Bay today and speak at the Berkeley Initiative for Transparency in the Social Sciences (www.bitss.org) about the need for (and feasibility of) adopting preregistration of studies making causal claims with observational data. #OpenScience

"With Silicon Valley in full AI hype mode, we need independent studies of AI in education that we can trust to fairly evaluate this technology’s impact, positive or negative. We’re not getting that right now and it’s a problem." open.substack.com/pub/buildcog...

Causal inference friends, check out The Case for Preregistering Quasi-Experimental Program and Policy Evaluations by @tomdee.bsky.social tom-dee.github.io/files/Dee_Ev...

In April 2025 I delivered a speech at the ASU+GSV ed-tech conference titled "AI Will Not Revolutionize Education." It touches on human cognition, gen AI, and the nature of scientific and social revolutions. I worked hard at this, I hope you'll watch and share. www.youtube.com/watch?v=u0_t...

A study by Professor @tomdee.bsky.social and GSE doctoral student Daniela Ganelin suggests that access to CS Principles could account for roughly two-thirds of the growth in AP computer science exams taken nationally over the past decade: ed.stanford.edu/news/stanfor... #EduSky #AcademicSky

Need some good education news? Over the last decade, the number of students taking an AP Computer Science exam more than tripled and that was no accident. In a new @pnas.org study, Daniela Ganelin & I find that roughly two-thirds of this growth can be attributed to the new AP CS Principles course.

Stanford University researchers studied the effects of the San Francisco Unified School District's math course pathway reform. Their work provides insight into policy reform and "increasing enrollment of students from historically marginalized groups in advanced math courses." ➡️ bit.ly/4l8vwJN

I just shared this "continuous improvement" toolkit with someone who approached me about how to drive positive change in their school district. This useful product, which is from a recently cancelled Regional Educational Laboratory, is an example of what this Administration is defunding.

Professor @tomdee.bsky.social, who uses school data to research chronic absenteeism, teacher performance, and high school graduation rates, discusses the recent staff reductions at the National Center for Education Statistics. #EduSky #AcademicSky

"We panicked over the first deaths, mourned and memorialized the first hundred thousand and then, eventually, stopped counting — and started instead to pretend it had never been that serious." www.nytimes.com/interactive/...

Join the doctoral student group TOMORROW at 1 PM ET for a workshop on Surviving (and Thriving) in the Hidden Curriculum of Graduate School. Register today: fsu.zoom.us/meeting/...

SF is really something else…

Hey doctoral students! Has the optimism with which you started graduate school turned to frustration? That's sadly common but needn't be. Join us online tomorrow and I'll share my frank advice. I promise to not speak for more than 20 minutes before open discussion! @aefpweb.bsky.social

🎓✨ Surviving (and Thriving) in the Hidden Curriculum of Graduate School Join @tomdee.bsky.social on Thursday, the 27th from 1-2 PM ET for insights on navigating the unspoken rules of grad school, followed by a broader Q&A session on navigating the #AEFP conference. Link: tinyurl.com/mpewfrsr

I just walked by the new @stanfordgse.bsky.social building and saw the iconic red roof going into place! I'm also impressed by these workers standing on a pitched roof while casually playing pitch & catch with these heavy tiles.

Journalists, can someone please FOIL this (and the other grant cuts), please? Name, title, amount, recipient, full text of grant. I - and I suspect many of my colleagues - will be very happy to help you analyze large volumes of text data very quickly.

The National Network of Education Research-Practice Partnerships (NNERPP) @rpp-network.bsky.social is on Bluesky. And I'm glad to be their first follow. #EduSky

SUPER BOWL CHAMPIONS! THIS ONE’S FOR YOU PHILLY!

Nick Sirianni's first four seasons as an NFL head coach: * Top-5 winning percentage in NFL history * Two Super Bowl appearances * One championship

This team was Howie Roseman's masterpiece. The most loaded Eagles team of my lifetime in terms of pure talent. Roseman has now built two championship teams with two different quarterbacks and two different head coaches. Looking like a HOF resume.

Today's NAEP results—& the apparent role of chronic absenteeism—are unsurprising to any close observer What's curious to me is this evidence-based sense of calamity doesn't really shape broader public sentiment. In fact, satisfaction is rebounding!👇 Is it crisis fatigue? Biases in info & judgment?

The growing number of mental-health first-responder initiatives reflect “rugged common sense and basic humanity." However, “the success of these initiatives is not a foregone conclusion." thebadgerproject.org/2025/01/28/d...

Education and immigration advocates say Trump’s move to deny citizenship to some U.S.-born infants will do lasting harm to children and schools. @jonapolitano.bsky.social reports www.the74million.org/article/22-s...

Get that "holy wooder" to New Orleans #GoBirds #FlyEaglesFly #SBLIX

“The Gulf of America” thing is so stupid, it’s strangely comforting to me. I can’t really explain it. Maybe it’s that even if I end up being executed for the crime of virtue signaling I will have lived my life never, even at my stupidest, having been that dumb

Amazing to see city after city paper issue reports about how crime and homicides fell in 2024 - Baltimore, Chicago, Detroit, St. Louis, New Orleans, Columbus, Memphis, Philadelphia.

SFUSD's math coursetaking reforms that delayed algebra led to fewer students taking AP calculus (driven by AAPI students), but these effects grew smaller over time. Coursetaking equity in the district did not improve. @tomdee.bsky.social @snovicoff.bsky.social journals.sagepub.com/doi/abs/10.3...

Interesting dive into the stunning, latest math assessments. This heterogeneity in the US math score declines (e.g., by gender, grade, achievement level) doesn't easily comport with dismissive narratives that suggest it's simply a post-pandemic decline in test effort.

I appreciate this cogent summary of our study of the Algebra I Initiative (i.e., targeted acceleration + supports for instructional differentiation). And I share concerns that a replication and scale-up are not necessarily straightforward. #EduSky But... fordhaminstitute.org/national/com...

College-admissions data like these often feed a "calculus vs. data science" debate about HS math. However, I encourage you to approach that potentially healthy debate cautiously. The definition of data science is contested & it sometimes embeds large but tacit declines in academic standards #EduSky

I have an op-ed in the NYT today about how to reduce crime. The key idea, based on decades of strong research evidence: focus on increasing the probability of getting caught, not the punishment. www.nytimes.com/2024/12/07/o...
