I don't understand why people are using the relative stability of England's PISA scores as evidence that reforms haven't worked. If [choose your pet theory] is causing declines in most rich countries, flat scores must mean that something in England is countering this trend. 5.5K views · 77 likes · 8 reposts · 7 replies Open on X →

Math(s) tweeps: I forgot to post this last week (when it would have been topical). Turn 11 at Monza is called the parabolica, but it's actually a clothoid (Euler spiral): the radius of curvature decreases steadily, so drivers can unwind the steering wheel at a constant rate. 4K views · 8 likes · 0 reposts · 0 replies Open on X →

I asked @ChatGPT about RCTs of school improvement initiatives and what it produced was not perfect, but interesting enough for me to ask for it as a report, which you can find here: https://t.co/k73OFso2ka. Full disclosure: no humans were involved in writing this report. 6.9K views · 16 likes · 1 reposts · 3 replies Open on X →

Public service announcement: if you want to use PISA scores to identify particular jurisdictional policies as the reason for success, you need to be sure that you have controlled for things that are nothing to do with teachers, schools, and policymakers (like private tuition). 8.9K views · 77 likes · 17 reposts · 12 replies Open on X →

A lot of politicians seem to have one of two responses to disappointing test results: 1) say the tests don't measure anything important so they can be ignored 2) use them as pretexts for introducing their pet policies. I'm not sure which I despise more. 1.9K views · 42 likes · 11 reposts · 5 replies Open on X →

Tesla have an 'unboxed' manufaturing process for their cybercabs. I didn't know what that meant. I do now. Rather than building one Cybercab sequentially along a conventional assembly line, they build several major sections in parallel and joins them together near the end.
