#NCTMCHI24 #MTBOS now I'm questioning yesterday's burrowing into developmental math .... but it's not too late to get enough nmaes and info to search for the interesting stuff I missed (tho' something tells me the oil and blessing part isn't going to be online :P )

Sharon was kind enough to share a folder of thin-sliced resources here : https://drive.google.com/drive/folders/18ivBhybOqzpCWKUUrAHsBpEgCYArWG5a

Three key steps to thin-slicing

"You remember your textbook? That's typically a thin-slicing in the homework"
You don't need to reinvent the wheel for your first draft.

Sharon Soule is from Coleville CA.
She's the only math teacher in her 50 student 9-12 school.
She's using @pgliljedahl "Building Thinking Classrooms" with a community throughout their high school career.

Great to hear about my #chatOAME presentation from a friend's conversation with others:
'There's so much fluff out there about #Al, often from those looking to profit from talks or books. #chatOAME offers practical ideas that real classroom teachers have successfully implemented.'

It's nice to see Papert mentioned in a presentation.
(Though it was led by a pair of ed profs, as much of #NCTMCHI24 now is.)

"Knowing from Memory" =/= Memorization.

This is definitely a call-back to Aldous Huxley's "Brave New World' and the introduction of hypnopaedia : https://ecampusontario.pressbooks.pub/englishliterature/chapter/brave-new-world-chapter-two/#:~:text=%E2%80%9CThe%20principle%20of,Nile%20is%20the%20%E2%80%A6%E2%80%9D

Miss @pgliljedahl "extra" #NCTMCHI24 presentation Thursday afternoon?
His slides are here : https://docs.google.com/presentation/d/1hP86GDYXZxE8r0BNH3ujm9f_U0_rmgPA/edit?usp=drivesdk&ouid=110413640069642866472&rtpof=true&sd=true but you really have to see it live, as his commentary is essential.

Rules for Checking Understanding with Mild, Medium & Spicy:
#1 Sit down and do your own
#2 Choose where you want to start/go
#3 Check your answers; if you need help, get help. If someone needs help, help them.

Presented #chatOAME at #NCTMCHI24 at Noon today.
Participant : "This is the first implementation of #AI in education I've seen that makes sense."

Thanks @OAMEcounts for supporting this project.

Ah... Interesting proviso. One class of #vr students in one teachers class provided a large negative effect. Once removed, there was a positive effect.
#NCTMCHI24 #mtbos

Well in this particular study, #vr students did worse compared to non VR students.
#NCTMCHI24 #mtbos
Further research in classroom settings is needed, clearly.

So how effective is #vr in geometry anyways?

@ilanahorn.bsky.social uses her Opening Session as a community building event -- "What does it mean to gather together [in person]?"
"In a better world, what would mathematics education look like?"

#polypad gets a "Compute" option on the dropdown option ... it will measure area, perimeter, and other contextual-aware aspects.
And it will assign it to a variable that responds dynamically.
AND it will tabulate as you move objects
