LLMs are based on dynamical systems, yet we don't do any of that mathematics in K12 -- even though we had standards and courses in some jurisdictions for high school (#onted did!)

What maths are involved in #AI?
Exactly what @NCTM proposed in the 1990s and forward.

Angela leads the room through how to do the design, guiding thoughts on language, mathematics and art

Class particiption time at Angela's session... A long queue of math teachers about to be engaged in art
At #nctmatl25 #mtbos #mathed
"Every student has the chance to put their own spin on the art"
"Art and Math transcend language -- I had a student who didn't speak a word the entire year ... for a child that struggled day to day to learn our language, he had a chance to shine"

I really appreciate that Angela is the first presenter to use closed-captioning in her presentation -- in fact, she insisted that the audio folks made it work.

"One of the best things you can do as a teacher is to be in the situation of a student, so you know what it feels like again"

30-40% of Angela's students are special needs; the school of 160 students PK-8 focuses on inclusion.

Issues in lesson plan generation using #AI at #nctmatl25
#mtbos #mathed
I read ~10,000 teacher prompts they made to #AI
At #NCTMatl25 Friday @ 1pm, come hear what I learned about how and why math teachers use #AI for their classes, and how that can improve your use.

I'm in Atlanta for the @NCTM Conference!
Friday I get to present w/Cynthia Shi on our work developing, designing, using, criticizing & theorizing with & about #AI in math class, especially for preparation, content development, assessment & knowledge.

Whenever a reply to a teacher involves a graphable equation or table of data, the teacher can click on a Desmos chip and it opens to a Desmos graph automagically!

I appreciated the Seneca CEO's push back -- "We have to trust our educators"
Peter Singh TDSB : how do you ensure that time saved by #AI doesn't turn into "latte time" (his words) for teachers.
Well first. Every time saving innovation over the past hundred years has not reduced teacher work hours.
And second. OFFENDED.
