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.



More than five years after the UC system lifted its standardized testing requirement, a coalition led by UC Berkeley math professors argues the drop in students’ math levels is “severe.” sfchronicle.com/california/art…


University of California STEM professors want standardized tests back due to severe math deficiencies among students: “We now observe preparation gaps so severe that instructors must reteach middle school mathematics” “The current admissions metric, based primarily on GPA & essays, can no longer reliably distinguish readiness for university-level STEM majors in an era of severe grade inflation & AI assisted application essays”
