Students who took notes by hand scored ~28% higher on conceptual questions than laptop note-takers. Writing forces your brain to process and compress ideas instead of copying them.

@leightjessica Up vote!! I feel like I am ahead of my colleague in the department, but woefully behind other colleagues in the building and social media.

Living in the AI era is stressful because you have to find time to -learn to use new AI tools -try to accomplish your new normal work goals with the new tools -read everyone else's social media posts about how productive they are using AI -stress out that you are losing out in the productivity race -think of new social media posts about AI (possibly using AI) It's exhausting

@Ingar30 Are you running this on your machine? (I assume yes.) What rules do you have in your markdown file so that it does not wreck your machine? This has been a limiting step for me.

These are all pretty simple examples, but I'm working on much more advanced tasks too where it also seems to do an amazing job. It's pretty clear from my perspective that Claude Code is by far the biggest improvement in LLM infrastructure basically since we got access to GPT 3.5.

There's lots of hype around @Claude Code right now. I actually agree it's a game-changer. I started with a simple request: create a fake data set and make a standard error bar chart. 🧵

@alexolegimas I think we need a workshop to catch up. Something "COVID esq" where there were mass online zoom meetings discussing these developments and demonstrating executable examples. I feel most of my use of AI has been for administrative purposes and as a coding assistant.

If you’re an economist, or any sort of social scientist, I’m not sure how you can look at the chart below and keep doing the same type of research you were a year ago.
Noam Brown@polynoamial

When GPT-5 was released, some folks claimed AI progress was hitting a wall, whereas others said progress would continue. GPT-5.2 was released 2 months ago. GPT-5.3-Codex was released 2 days ago and is twice as token efficient for coding. It's clear who turned out to be correct.

@jt_kerwin Ours is not public information. I cannot imagine how the faculty reacted when this went public. I wounded if it affected the distribution of grades after being made public.

@UofLEcon We can actually look up all the grade distributions for every UW course on a website called dawgpath. (Creating that website was a batshit decision but I digress). Anyway here’s the class I teach; we grade down to the 10th of a grade point, the mean is 3.2 and the median is 3.3.

@jt_kerwin Same. *BUT* % of Ds & Fs are heavily tracked and there is a strong pressure to increase graduation rates.
