My specialty is taking the talk-heavy instructional routines that work so well in K-8 math and using them in K-8 computer science (where they are an absolute *revelation*). My #NCTM session is a hands-on tour of those. I love showing math teachers (often CS-adjacent) how well they work. 🤓
I sometimes forget how much i loved product management.

A good passage from the always lucid Jason Cohen: “A great strategy, that doesn’t align with your strengths, is a bad strategy for *you*.”

Ah, but the alignment. There’s the rub. 😏
I use this Adjacency Matrix to decide how to expand beyond incremental improvements.

e.g. new market segment, new product offering, new positioning, new ICP.

A simple workshop that evaluates new business ideas relative to your existing strengths -- the key to expanding without overreaching.

Maybe it’s just the Humanities professor in me, but let it be noted that events of today (ahem) have demonstrated the value of being able to assess a large volume of qualitative data and do careful textual analysis with deep attention to context.

“Watson was ‘self-taught.’ He saw his double-helix discovery as proof that outsiders, unburdened by establishment thinking, could see and achieve what insiders couldn’t.”

Thing is, sometimes outsiders *do* make the breakthrough. It just sucks when they are awful and get the reason wrong.
A Sharon Begley byline, almost 5 years after her death.

Upon hearing the news James Watson had died, a STAT reporter said in our Slack, "I wish I could read what Sharon would have written."

Incredible news: Sharon in fact did pre-write a Watson obit. And it is masterful and excoriating.

LLMs are now widely used in social science as stand-ins for humans—assuming they can produce realistic, human-like text

But... can they? We don’t actually know.

In our new study, we develop a Computational Turing Test.

And our findings are striking:
LLMs may be far less human-like than we think.🧵
Computational Turing Test Reveals Systematic Differences Between Human and AI Language
Large language models (LLMs) are increasingly used in the social sciences to simulate human behavior, based on the assumption that they can generate realistic, human-like text. Yet this assumption rem...

In k-8 CS edu: “The fact that code blocks are present doesn’t mean that ‘computational thinking’ is being developed.”
Kids can complete coding puzzles and tutorials by rote. We shouldn’t be satisfied with that.
The fact that chips or a number line are present doesn't mean that "conceptual understanding" is being developed. You can follow a rote procedure with integer chips or number blocks.

I absolutely never appreciated how Green Day's "American Idiot" is about media literacy!

"Don't wanna be an American idiot
Don't want a nation under the new mania
And can you hear the sound of hysteria?
The subliminal mindf**k America..."
