Yeah I noticed it a few months ago.

On the flip side, imagine how excited I was when I saw there were a bunch of new Vi Hart videos just waiting for me at vimeo!

BTW Vi Hart's videos are available on Vimeo. Apparently they pulled their YT videos due to bad Terms of Service.

The Vimeo views are in the dozens, rather than in the millions as was on YT. Consider becoming a Vi patreon.https://www.patreon.com/vihart

I'll be teaching a 1-hour seminar course for first time graduate teaching assistants in math. Any recommendations on quick/digestible articles or excerpts for such students? Just things with easily implementable practices for folks who may or may not have taught before.

For context, the problem is asking things like "at which point is f(x), f'(x), f''(x) greatest/least?"

"A graph of a smooth blue curve with two local minima and one local maximum. Six vertical dashed lines labeled x1 through x6 are shown beneath the curve along the x-axis. The curve starts high to the left and decreases to a minimum just after x1. The function then increases higher through x2 and achieves a local maximum at x3. The function is decreasing when it passes through the y-axis and decreasing more steeply at x4. The function achives a deeper minimum at x5 before rising steeply through x6.

I've been spending the summer adding alt text to various online graphical problems, but I could definitely use assistance if any of y'all have experience. As an example, here's a graph and you can see my alt text the picture. How would you describe it in a manner that is helpful for screen readers?

When I applied to Baylor for undergrad I had to choose a denomination of faith, which I did not have or know anything about (raised Catholic, very lapsed). I chose something called "Disciples of Christ" because that sounded like something the university wld like. To this day I've no idea what DoC is

I've been out of the pbl training gig for years now. Curious what it looks like when AI can build a content oriented project (at least the bones of one) in seconds. Like what do pblworld, new tech, hth, pltw offer in terms of project trainings now? (This is not a troll I'm genuinely curious)

I'll be teaching a Calc 2 course this Fall. It's intended to be a Calc course for Biological Scientists. Id like to do some "lab-like stuff," applying Calc concepts to Science. Days where we use Calc to solve a Science problem and do a writeup.

Anyone in #edusky have experience w lab days in math?

UW: Women in STEM, Latina Youth Conferences β€œlikely not allowed” under new DEI guidelines Both conferences were set to celebrate their 25th anniversary in 2025, but fall afoul of a right-wing crackdown on diversity programs. The annual Shepard Symposium could survive but is β€œunder review.”

It's so sad and stupid.

When I started my PhD at UWyo I was excited specifically because it was a bastion of inclusion and diversity. That was in 2020, just five years ago.

Now they're are cancelling Women in STEM and Latina Youth conferences because it would show "preferential treatment."

Now that we see how easy it is to gut federal institutions, how about we abolish ICE next time we get the chance?

Renaissance High students hold walkout after West Ada teacher was asked to remove "everyone is welcome" sign Students at Renaissance High School organized a walk-out in response to a West Ada School District teacher being told to remove a sign from her classroom reading "everyone is welcome here."

This is heartening tho

I've never been nor would do I ever want to be an administrator so I can't fully understand what goes into it but if I had to tell a teacher to remove this sign I'd probably start reevaluating things.

West Ada teacher stands firm after she’s told to remove β€˜Everyone is welcome here’ signs Sarah Inama said she was told by administrators that her signs β€œdon’t allow people to express differing opinions.”

This sucks so bad. I've delivered PD in West Ada.

If you can't even put this anmodine of a sign up without state and admin intervention....
