Was expecting mathematical symbols made of donuts, so I am pleasantly surprised to see mathematical patterns themselves! #dallemini #iteachmath

Which schools benefit most from the proposal to lower class size caps in NYC? A snapshot of elementary schools in 4 NYC districts: * 21 = proposed avg. cap for elem. classes * darker dot = higher pass rate on state test (4th grade math) * left to right = decreasing affluence

"Saami" is a low-floor high-ceiling numbers game that is accessible to both toddlers as well as challenging for adults. My 2 year old can understand it and yet I have not made it past level 25. Try it! numbershapes.com/interactive… #elemmathchat #maths #mtbos

New question: Harvard says "It's ok, you can take calc freshman year!" What should they do to support & retain STEM majors who did not have calc & other advanced/extracurricular STEM opportunities in HS? (Note: ~7% at H did not take calc in HS ~15% applied as Humanities majors)

Replying to @Harvard
@Harvard Communicating really important admissions policies regarding high school maths courses. They want conceptual understanding & mathematical reasoning to make sense of the world. Data science, CS, Stats, & Calculus all regarded as equal. college.harvard.edu/admissio…

Also important for context: x.com/boazbaraktcs/status/15…

As co-director of undergraduate studies at @harvard CS, this is highly misleading. Do not confuse minimum admission requirements with advice to students. These courses are not all equal, *especially* if you intend to concentrate in quantitative fields including data science

I do think part of this conversation should be about why STEM higher ed is configured in such a way that these high-privilege experiences are expected/necessary. (My bias is I never did any of them and still did a math major at a selective school)

Interesting questions about Harvard's statement addressing "Is there a specific math requirement?"
Do you think this is just disingenuous or actually harmful or both? Harvard is going to accept whoever they accept. Ultimately one small school cannot really change things. But it’s nice to hear them say “you can take calculus freshman year”. Isn’t that a positive?
