1/20 Most people only know Jaime Escalante from Stand and Deliver. Few know there was a Chinese immigrant teacher who did something just as extraordinary: For 20 years in the Arizona desert, he took the state’s poorest Indigenous, Latino, and Black middle schoolers — many with broken English and shattered foundations — and turned them into statewide champions. His name is Michael Xu. The “Sage from the East.” A man who survived China’s Cultural Revolution, hard labor in the jungle, lifelong dyslexia, and insomnia… yet became a legendary math teacher. This thread is the first time his full story is being told. And it reveals something much bigger than one teacher’s success.




When I wrote about Alpha School, I said that their main innovation was ideological. That's because in the past 100 years something like Alpha's structure has been tried a number of times, like the Winnetka Plan.



Black students have been excluded from high-quality mathematics for generations — with dire outcomes academically and professionally, a California-based math equity group found. Read more from @Jo_Napolitano here: buff.ly/0O64Smh


La ansiedad matemática no es un problema menor ni solo “falta de base”. En una comparación con PISA en 67 sistemas educativos, la ansiedad matemática se asocia negativamente con el rendimiento en todos ellos: penalización media de 22,9 puntos PISA. Más que la brecha media de género en matemáticas. Ainhoa Vega de la UPV en el curso de la @UIMP





Very interesting new high school in Rwanda: "The African Olympiad Academy aims to develop nascent Math and Science talent from Africa into engaged, globally-competitive problem solvers with a deep commitment to the continent." 1/

Higher graduation rates ≠ stronger student preparation Some strategies districts use to artificially boost graduation rates: -equitable grading -credit recovery programs

Our immigration policies need to be reformed to allow the best and brightest to be educated in the USA and stay here to create value for our country. As long as their values are aligned with the long-term interests of our country, their visas should be fast tracked. Can someone in immigration help this young woman?
