I NEED HELP! Please take this quick, meaningless 19 question survey so I can get data for my students to learn stats! I did a similar version a few months ago but missed an important question type. Even if you did the old one, please do it again! Please circulate widely!

One of the big ideas I wish was better understood in ed discourse is the difference between textbook-adoption states (red) and non-textbook adoption states (blue). The levers of power are so different but so often ignored. AKA This could NEVER happen in NYS. www.nytimes.com/2026/04/07/u...

No joke: I got angry hate mail today for writing an obituary of a Black woman scientist—because the person felt she did didn’t deserve the recognition. Which just makes me want to share it again: www.nature.com/articles/d41...

She made key contributions to US cold-war science despite facing huge barriers as a Black woman.

Very good piece on the quite fast rollout of "AI-powered" textbooks in South Korea. The government went from making the textbooks mandatory to supplementary because of complaints and now the textbook companies are suing because "the market suddenly disappear[ed]." restofworld.org/2025/south-k...
