I am excited to announce that will be running a learning community on Team-Based Inquiry Learning through the MAA OPEN program this fall. Please share with anyone interested in bringing collaborative inquiry-based pedagogy into their lower division math classrooms.

Apropos of nothing, my CTL is awesome and @bestlab1995.bsky.social and his team there are awesome. No one taught me how to teach until I got on the job and my career would be drastically different without them.

sometimes you just gotta email the ombuds

Check out my recent @mathtech.org post showcasing opportunities to get involved with Doenet.org including a funded workshop June 1-5!

I thought this was Smash Bros gameplay as I scrolled by at first

Actually he's just rolling his eyes

satisfy automated checkers but without providing materials that are actually digitally accessible. Will some people kick the can down the road? Sure. But this gives us more time to figure out workable solutions that will avoid what @clontz.org suggested people are talking about: not putting

Here's the full details. I look forward to working with the rest of the @mathtech.org community to support faculty in implementing these changes, but appreciate the extra year to get it done well! www.federalregister.gov/documents/20...

This is the right decision and very welcome news. Working to make digital accessibility a requirement of public institutions is important and correct, but the one year extension will allow everyone to do things "right" rather than rush into compliance.

Has anyone done this for oeis.org/A000040 ?

#MathSky peeps interested in AI: Participants in the Milestones for Autonomous Math Research (icarm.io/project/mile...) will have some remote office hours tomorrow (Fri 4/17) to onboard people interested in the project. Visit @code4math.org Zulip for link: code4math.zulipchat.com#narrow/chann...

By popular demand, institutional licenses can now be purchased at PreTeXt.Plus/subscriptions Please, if you can pip install things, don't pay money for open source products! But if your office mate just wants to Start Writing, we're here to help! Basic/free tier is pretty good too... #MathSky

Claude et al don't understand why your image is important for your students; these slot machines cannot write alt text that makes your figure accessible.

I have been talking a lot about accessibility in Math course materials, and the answer is NO you SHOULDN'T use ChatGPT to write image descriptions, I don't care if you think it's hard to write them.

Lots of cool work being shared in the @amermathsoc.bsky.social accessibility call. Of course, here's my favorite. PreTeXt.Plus

It was much faster to write a single question and share the output with PreTeXt.plus than it would have been to make a new project or edit an existing one, rebuild the whole thing multiple times (a good argument for not using any significantly large existing project), commit, sync, and deploy!

Guess who found a bug that I should have waited on a review to catch (it's @oscarlevin.com )

Even if you're a PreTeXtBook.org power user like @chrissysafranski.bsky.social (she'll hate that I called her that lol), here's a neat trick: sustaining subscribers to pretext.plus can generate share links that include source code, perfect for sharing code snippets: pretext.plus/projects/c80...

Importantly, PDF supports basically none of this.

The RIOS Institute @rioscommunity.bsky.social is sponsoring a learning community on Alternative Grading, beginning May 5 (and ending right before @thegradingconference.com). Join me and @melanielenahan.bsky.social for a weekly community where you design an alt grading scheme for your upcoming class.

Leo: "The message of the church, the message of the gospel -- blessed are the peacemakers. I do not look at my role as being political. I don't want to get into a debate with him. I don't think the message of the gospel is meant to be abused in the way that some people are doing."

Here's the pitch: all the behavioral and formative stuff I don't want affecting a final grade gets tallied up and measured as an "engagement score" (think arcade scores, not exam points). Then every so often folks in the lowest 20 percentile are required to check in with me in office hours.

Had an epiphany this morning on how I can solve all my classroom engagement issues: I just need to write another web app...

If I were a math association with a special focus on the teaching and learning of mathematics, I wouldn't be gloating that my signature math event frequently results in players getting a score of zero, but that's just me.

i think it's beautiful that to mathematicians latex is low learning curve and xml is high learning curve

A quick demo of the new conversion feature!

Proud new sustaining subscriber! I was having a Friday slump but I can't wait to get to work now to play with new toys.

LaTeX-style PreTeXt is now live at PreTeXt.Plus. Use an edu email to create your account and check it out! #MathSky

Faculty and students can now create a pretext.plus account without needing an invite when they use their .edu email address! We'd love your feedback at the #pretext-plus channel of mathtech.org/chat!

gee whiz I wish MAA Connect was a website humans would want to use

Hey #MathSky here's a cool opportunity to connect with other STEMM faculty interested in sustaining and strengthening our teaching and learning communities through open educational resources! mathtech.org/2026/03/30/b... @mathtech.org

Finally doing my Faculty Activity Report, apparently I have four papers and a book chapter this year? Could have sworn most of that was on my report last year. It... it's been a loooong year lol

/usr/bin/python: No module named pip oh it's going to be one of THOSE days...

Wasn't the biggest L of the day yesterday, but my disappointment was real when I found that my favorite breakfast joint had replaced their hand-breaded chicken with a cafeteria-ass Sysco patty. 😭

What a terrible day to own a phone and know how to read.

π-Base: a model for curated mathematical databases #MathSky pi-base.org

Def tooting my own horn, but even for TBIL.org I'm finding it much nicer to copy source code into pretext.plus to make my edits, then use GitHub.Dev (and not a full codespace or local installation) to contribute changes... Compare pretext.plus/projects/637... and github.com/TeamBasedInq...

Well I just got jump scared by my YouTube Shorts showing someone singing the praises of this month-old, interestingly-named project. github.com/chenglou/pre...

Movie was fun and post credit scenes were too. But if the next movie doesn't end with Masahiro Sakurai recruiting Mario into the Smash Bros Initiative I'll riot.

Going to the movies

Nothing is more macabre than the way it's spelled.

Why was π afraid of θ? Because θηζ.

I can't believe I never posted my original #MathOfMario video essay. (It's not very well produced but it was fun!) www.youtube.com/watch?v=A28Y...

What existing implementations exist for ordinal/cardinal arithmetic as software? #MathSky code4math.zulipchat.com#narrow/chann...

I'm ready to throw the towel and admit zero is a natural number... In fact the Peano axioms imply ZERO IS THE UNIQUE natural number. Here is the proof: youtu.be/IgwYNMJuwKY

Ahead of the SCOTUS arguments about birthright citizenship: when I was born (in Wisconsin) my father was not yet a citizen - just like John Roberts' grandfather. What's your immigration story?

Put this in @merriam-webster.com next to the definition of "overengineering": youtu.be/WhSjcF-qjXs

I really just need 16 of them.
