Pedro De Bruyckere@thebandb.bsky.social · 2d agoYou can design a school for collaboration, co-teaching and flexibility. But that doesn’t mean they will happen. A fascinating new Finnish study shows what happens when pedagogical dreams meet school reality. wp.me/p2nWPo-6gj

#BlueLZ "With little prior knowledge, explicit instruction first was clearly better. For a middle group, the order made no statistically significant difference. With sufficiently high prior knowledge, however, inquiry-based learning first was better."
Pedro De Bruyckere@thebandb.bsky.social · 4w agoExplicit instruction or inquiry-based learning? Perhaps that’s the wrong question. A new conceptual replication again shows that the order matters, as does what students already know. wp.me/p2nWPo-6cB
#BlueLZ "England certainly offers an interesting and potentially instructive story. But we should not forget what happened to previous educational role models. Remember Finland?"
Pedro De Bruyckere@thebandb.bsky.social · last mo.England, Scotland, Wales, and Northern Ireland have followed different paths in education. Is curriculum part of the explanation? Perhaps. But SES, timing and questions about the English sample complicate the story. My closer look at PISA 2025 in the UK. wp.me/p2nWPo-6bt
#BlueLZ #PISA2025 "The part that intrigues me most is the hint that England is both a top-performing country and one with relatively small differences among groups of students."
Pedro De Bruyckere@thebandb.bsky.social · last mo.PISA 2025 is here. Beyond the rankings: less reported test effort, inequality sometimes narrowing because advantaged students decline more, falling environmental awareness, and a potentially fascinating England story. My slightly idiosyncratic dip into the PISA grab bag. wp.me/p2nWPo-6bh
#BlueLZ #PISA2025 "...England that is bucking this trend ..."
Paul Kirschner@paulkirschner.bsky.social · last mo.A first look at PISA 2025 A hell of a lot of correlations, but all going in the same direction. A good curriculum and explicit instruction seem to work! fillingthepail.substack.com/p/a-first-lo...

Pedro De Bruyckere@thebandb.bsky.social · last mo.How many meta-analyses does it take to know whether something works? Apparently, fifteen are not enough.

#BlueLZ "As with so much in education, the precise results depend strongly on what the learner does, what the AI does, what task is being performed and how the whole thing is embedded in teaching."
Pedro De Bruyckere@thebandb.bsky.social · 2mo agoResearch on AI and education is exploding. Stanford's repository has already passed 1,500 studies, and even the number of meta-analyses is becoming hard to keep up with. But are we really learning that much more? This blog has an AI problem. wp.me/p2nWPo-69H
Pedro De Bruyckere@thebandb.bsky.social · 2mo agoNice to see our book The Psychology of Great Teaching described as “EXCELLENT”, “comprehensive (and readable)” & “FULL of useful applications for your classroom”. Even better: Heleen Reynolds has created a very useful summary of the book, including a practical ‘Do This’ version. wp.me/p2nWPo-69A
#BlueLZ "Of course teaching is a profession in which many things come together. Experience, adaptability, relationships and, let’s be honest, quite a bit of improvisation too."
Pedro De Bruyckere@thebandb.bsky.social · 2mo agoThe average student doesn't exist. Neither does the average classroom. And, perhaps more importantly than we sometimes realise, neither does the average teacher. Some thoughts on why evidence-informed should not mean evidence-dictated. wp.me/p2nWPo-67I
#BlueLZ "Nearly a century later, we have vastly better methods, far more data, and hugely richer sciences on which education can draw. Whether we’ve also become better at resisting the temptation to turn science into recipes is another matter."
Paul Kirschner@paulkirschner.bsky.social · 2mo agoOnce a scientifically informed idea is turned into a uniform procedure to be followed regardless of circumstances, it ceases to be an expression of scientific thinking and becomes just another rule-of-thumb, albeit one wearing a lab coat. paulkirschner173727.substack.com/p/the-scienc...
#BlueLZ "The authors therefore argue, and this may surprise you, for continued explicit instruction, modelling and scaffolding of self-regulated learning, including for older students."
Pedro De Bruyckere@thebandb.bsky.social · 2mo agoWe expect students to become increasingly independent as they get older. But are we also teaching them how? A new review on self-regulated learning offers little that is revolutionary, but it does highlight an important reminder and an intriguing research problem. wp.me/p2nWPo-66Z
#BlueLZ "The study does not really examine whether AI works."
Pedro De Bruyckere@thebandb.bsky.social · 2mo agoA new meta-analysis reports large effects of AI in education. Solid methods, but a young and uneven evidence base. The real question isn't whether AI works, but which AI tools work, for whom, and under what conditions. wp.me/p2nWPo-65j
#BlueLZ "In advanced economies, average learning loss remained relatively limited. At the same time, however, the gap between advantaged and disadvantaged students widened considerably."
Pedro De Bruyckere@thebandb.bsky.social · 2mo agoWho paid the highest price for COVID school closures? A new international PISA study suggests the answer depends on where students went to school. In wealthier countries, inequalities widened, while in less affluent countries learning losses were more widespread. wp.me/p2nWPo-64V

Pedro De Bruyckere@thebandb.bsky.social · 2mo agoA second-order meta-analysis confirms that flipped classrooms generally improve learning in higher education. But the benefits don't come from the videos. They come from what happens during class: guided practice, feedback, collaboration, and problem-solving. #HigherEd #Teaching wp.me/p2nWPo-64O
#BlueLZ "AI may encourage some teachers to think less deeply about their lessons because it takes over part of the cognitive work."
Pedro De Bruyckere@thebandb.bsky.social · 2mo agoOne of the strongest AI-in-education studies so far asks a better question: not whether teachers save time, but whether students actually benefit. The answer is more nuanced than many headlines will suggest. wp.me/p2nWPo-64z
