I can't make you learn something. I can take you on a tour, show you the landscape, some good examples, come up with activities to sharpen your thinking, give you feedback when you try things, but you have to have the experience, you have to know that it's yours & only yours. I can't give it to you.

I desperately want that mug now. I made a comment to a friend today that I get to walk around and talk about math and spill coffee all day and it is a perfect existence for me!

Thinking about how a friend and I used to have "mail races". We would write each other physical letters and put them in the mail on the same day. Whoever had their letter arrive first won... I should she if we can get that going again

Also I should say that coming up with good examples is one of my favorite parts of teaching. Why should I give that up. The lazy cheat machine makes more work for me and takes away one of my favorite pieces of teaching.

Don't do that! Of the five examples it spit out only one of them actually fit the request. After 20 minutes of carefully checking each of the outputs by hand I finally had my examples put together. It took more time than if I had just started by hand and used desmos 3d grapher.

I forgot that I needed to come up with a few systems of equations that happen infinite number of solutions that can be parameterized for tomorrow. (I went kayaking with my kids instead....) Because of the time requirement I thought I would test out an LLM.

After 19 years I have entered the phase of writing warm up questions as poems. Today is my first limerick.
A whiteboard with the following limerick 

There once was a man named Descartes 
Who had algebra deep in his heart
For chance to be a hero
He solved 3x^3+2x^2+5x-2=0

I think normalizing science as a thing people can do is important. We do what we see. Many kids (and adults) don't have a personal connection to someone who does science and therefore never pursue it. If kids are exposed to pop science some of them will do that and some will learn amazing things

This is the best way I have ever found to teach properties. Are numbers commutative in /mathbb{Z}/p? What does that mean? Algebra 1 kids definitely can understand it! Then suddenly maybe sprinkle a little cryptography in there and you are going wild

Wow. All those numbers are prime numbers. Isn't that cool? And hooray you've taught them ℤ/p and are getting into interesting math. This stuff can be made accessible and fun for kids, we just force kids to memorize times tables until they declare forever they are bad at math

If you have windows kids can write in them with markers. They love it! Also student desks can be written on with markers! It is fascinating how much deeper the (math in my case) can get when you give a group of kids a marker and a good problem to solve.

IMO, senior faculty at top R1 institutions rushing to use AI to flood journals with papers before future students or early career researchers can have an opportunity is not just greedy, it's salting the earth of the discipline.

A big part of what I do is spend hours thinking about the best examples to illustrate what is important and what errors can arise. If we stop embracing that part of the job we are going to be replaced soon. There's already a lot of people who already think that we are just robots!

kearnsn.bsky.social @kearnsn.bsky.social · 05/06/2026
I complain about paperwork sometimes because yes it can be annoying! But I don't want to write questions that can be automatically graded by a robot. I want questions that a human has to decide the truth of. If we only do things that AI can do why have teachers at all.

Why would anyone choose to dwell, for even a second, in the Kafka liminal zone of “by AI” or “with AI”? When you can do literally anything else, why would you do this with your one life?
