Another of my #LostMath documents. The Magic Circle by Ted Ostrander and Arthur Wiebe. It is found on one website. I did it years & years ago with students, & still have one of the balls I created with the result. Give it a try! It is wonderful. #MTBoS #ITeachMath www.dropbox.com/scl/fi/kk35b...

Great thread. UK math teachers have started using the tag #MathsToday for positive math moments.

I have one in the mix right now from teaching children mathematics on routines. As well as the 'rules that fail series' of articles. Your advice is great. Thank you!

That is one of my goals. Now I just have to find 12 to 15 articles to build off of. Lol

Has anyone used the MTLT as a primary source of readings for a university math methods (secondary) class? I am revising my class for this semester, and considering doing so. Any experience you want to share? Thoughts in general? #ITeachMath #ITeachTeachers #MTBoS

It is just a flipped classroom, but the fact that AI is forcing that model on us all is what is frustrating.

As pointed out by @paulakrieg.bsky.social and noted by @mpershan.bsky.social, longtime #mtbos partner and collaborator Malke Rosenfeld passed away last year. She investigated and taught the mind-body math connection, engaging hundreds of teachers and learners in #mathart - dance! RIP great friend!

The struggle of using AI to short circuit learning is very problematic. Is AI forcing us to all use essentially a flipped model so that work is all done in class? How do we get to the Halmos "Don't just read it, fight it" idea when AI can even do the reading for us? #MTBoS #ITeachMath #MathSky

I took some complex & creative math ?? I gave as hmwk last year in a college course & put them in Gemini. It solved every one of them. With explanation. My ? is, what are university math faculty doing to make learning central to class when AI can short circuit learning? #MTBoS #ITeachMath #MathSky

What is formative assessment, and why should anybody care? With professor Dylan Wiliam

How wonderful to have an episode with @dylanwiliam.bsky.social on #TheyBehaveForMe podcast with
@amymayforrester.bsky.social and
@adamboxereducation.bsky.social who did the whole interview with a tiny baby in a carrier.

I bring it up repeatedly in my methods classes to show preservice teachers what students really think. They all agree with the findings. It is hard to move the needle of inservice teachers though.

Every time I see a post like this, I think of this research article with over 21,000 students. The top 3 words HS students use to describe high school are Tired, Stressed, & Bored. Of the top 10, only 2 are positive. We can and must do better. doi.org/10.1016/j.le...

Session 1 of our Speaker Series, by @pamseda1.bsky.social, got Session 3's @jennalaib.bsky.social thinking: "When does it make sense to change [cultural] elements?... The answer isn’t a checklist or a directive. It’s a stance... I strive for intentionality & balance... Why this shift? & for whom?

The older I get, the less interested I am in contrived "contest problems," and the more interested I am in
- focusing on deep, enduring truths
- dwelling in mystery, contradiction, enigma
- finding beauty in simplicity

I just had a graduate, who is taking a leadership role in his department, ask for examples of algebra tests that have good conceptual questions. He wants to bring examples to his dept to encourage the discussion. Does anyone have any resources? #iTeachMath #MTBoS #MathTeaching #MathAssessments

Longshot question for my network. Is anyone in Hong Kong? I am looking for a book, and one copy exists in the world, in a library in Hong Kong. search.worldcat.org/title/513774... They won't even photocopy the table of contents for me. #FindABook #iTeachMath #LostBooks

One of their (preservice teachers) takeaways is that Black schools were literally closed in the South because they were outperforming White schools. Just one of the many things in the history of math ed.

I think so. There are so few copies of it in existence, but it is still technically copyrighted. I would love a chance to see something done with the amazing images though. If a printer does something w/ it, please let me know.

And this one by him as well really does exist in only 1 library. search.worldcat.org/title/513774... This is only in a library in Hong Kong according to my interlibrary loan folks.

Wow. Thank you for that information. It is really sad how few copies are still in existence!

I have all my math students read the Critical History of Math Education by Berry. It is chap 2? in the book Brilliance of Black Children. It always shocks them.

@tguindon.bsky.social @annlovesmaths.bsky.social @thestarcaller.bsky.social @ash-bans.bsky.social I just found the 3rd book by Dr. Shih. It is called MathGraf, and the single copy my library could find that exists *only* in a library in Hong Kong. In negotiations for a scanned table of contents now.

Sorry, inter library loan.

I did do an ILL for the mathgraf book. Maybe something can come of that.

This is FABULOUS! What a great way to show off what Dr. Shih did in his book. Love it! Thank you Tim.
