The product's design is the tool you use to distinguish. Say that, unbeknownst to you, 90% of your users are non-native English speakers. Is a non-native English speaker "stupid" because they misinterpret the simple English i

Bloom's paper largely focuses on when/how students get feedback and less on the particulars of the assessments. For example, maybe mastery learning works (in part) because it helps teachers pay attention in a group setting more li

That's not how conspiracy theories and magical thinking work. I grew up around folks who thought fluoride was in the water to brainwash us. I had an English teacher who thought the major news media was hiding the fact that we discovere

You're right! I confused the deductive system/language w/ the theory. Oops. Something like Presburger Arithmetic would've been a proper example.

There are two other conditions/premises that, arguably, play a bigger role in Gödel's theorems: 1. The theory must be strong enough to do a certain amount of arithmetic 2. The axioms of the theory must be computably enumerable So,

Maybe, but I don't really see what that gets you: 1. In an ultrametric space like the p-adics (ℚₚ), two open balls are either totally disjoint or one is a subset of the other 2. In an ultrametric space like the p-adics (ℚₚ), every ball

Society isn't a story and therefore doesn't have a protagonist.

I think the one-dimension "conformist" / "non-comformist" axis isn't useful. We all participate in orthodoxies that we're blind to (or at least not fully aware of). The only questions are "Which ones?

Absolutely! You can see it in this thread, even. There are folks excited by the prospect of using the phrase "aggressively non-conformist". pg is providing memetic ammunition for the very "culture wars" he claims he&#x27

If you write several essays about "the way society works" and they consistently resolve to a protagonist who happens to be very much like yourself, you're probably writing about your own mind, not society.

Spivak was my 1st-year college textbook and it convinced me to major in math. I highly recommend.

When I can, I actually forbid my students from using flash cards. If they don't have the scaffolding to make a concept stick, time is better spent building the scaffolding (IMO).

It might seem painful, but the fact is students will be reading lots of material besides what you personally prepare. That material will be referencing all sorts of "advanced" boilerplate things. One of the highest-impact things y

What's craziest to me is that someone thought you could put together two groups of students in a high stakes situation without first socializing the interaction. Half the point of school is to get students to first fail in a low-stakes
