The 2026 Winter Olympics figure skating ⛸️ free dance was scored by 9 judges The French judge gave Beaudry & Cizeron 🇫🇷 a 137.45 but only gave Chock & Bates 🇺🇸 a 129.74 All other judges were relatively close in their two scores 🤔 Judge No. 4 was just in a bad mood overall

NEW: IT'S NOT JUST THE UK! 🟢The UK is 14th OECD country to become coal-free. 🟢OECD coal power falls to less than HALF of its peak in 2007. 🟢All but 5 OECD countries have seen falls of at least 30% from peak coal power (lovely dataviz from @C_BruceLockhart) 🧵

Just fed the text of a book—Student Assessment, co-authored with Nancy Frey and Doug Fisher—into Google's Notebook LM (HT @emollick) and it produced a ten-minute podcast as well as a list of FAQs and a study guide. As Ethan says, "Seriously, just listen": bit.ly/47EtlYf

An interesting chart on the age distribution of athletes at the Paris Olympics. Youngest- Skateboarding, gymnastics Oldest- Equestrian, Triathlon It's kind of wild how young swimming skews compared to its close athletic cousins (track, triathlon, cycling)

this will be one of my favorite moments ever not just because it secured gold. nor because of the difficulty. because he is the only person on earth who not passing to one of these two, wide open, is acceptable.

Again, much of the conflict about math pedagogy is a disagreement about: a) whether math is a set of secret codes or something accessible on a concrete, sensory level. b) whether students have valuable knowledge to build on or not. This all gets easier if you get that.

AI detection in school is a losing game. AI detectors have high flaw positives & teacher intuition seems to work even worse: “Here we show in two experimental studies that novice and experienced teachers could not identify texts generated by ChatGPT among student-written texts.”

This should be the lede everywhere: “15yos from disadvantaged families lag their advantaged counterparts by five years of schooling. Indigenous students are around four years behind non-Indigenous students.” How can we allow such an inequitable education system to persist?!
