U.S. students score above average in reading. Here’s why that’s not good news.
PISA international test results show concerning global declines in student learning. U.S. students posted some of their lowest scores ever in math and reading, but other countries are doing worse.

"The concern is...epistemic centralisation. That arises when a narrowed and selective translation of the science of learning becomes a comprehensive account of learning. It can then become the benchmark by which other educational knowledge is authorised, marginalised or dismissed."

Gert Biesta just published a brief reflection on his important 2007 article, "Why 'What Works' Won't Work" in Education: "...whereas policy argues that practice should take research findings seriously, the same doesn't seem to hold for policy." onlinelibrary.wiley.com/doi/10.1111/... A 🧵:
Has Research on “What Works” in Education Been Looking at the Wrong Interventions? Revisiting “Why ‘What Works’ Won't Work”
Gert Biesta
First published: 02 December 2025 https://doi.org/10.1111/edth.70063  view metrics
SectionsPDFTools Share
Abstract
In this invited article, I revisit my 2007 essay “Why ‘What Works’ Won't Work: Evidence-Based Practice and the Democratic Deficit in Educational Research.” I provide a summary of the key arguments in the essay, explain why I used the phrase “democratic deficit,” examine what I have observed regarding the discussion about “evidence” in education since the publication of the essay, and show, through an exploration of the educational placebo effect, why the comparison between education and medicine remains problematic. I suggest that this may have important implications for the design of educational research. It also raises the interesting question to what extent existing evidence about educational effectiveness has been looking at the right interventions. Against this background, I reiterate my call for a broader spectrum of research approaches than only those that focus on the question of “what works.” This is as much a call for researchers as it is a call for policymakers and educational practice.

The meaning of science education isn't just: ✕ Knowing the content, nor ✕ Knowing how scientists work The major goal is: ✓ Learning to think about content like a scientist Through the content, students should understand the nature of models and learn how to infer explanations from them. #EduSky

2/2 Can't emphasize this finding too strongly: It's not just that explicit instruction of procedures is less useful than helping kids to construct mathematical principles for themselves. It's that explicit instruction of procedures can actually do damage by impeding understanding.
