Take two classrooms, both using the same fundamental idea to communicate a mathematical concept (like volume). Then, modify the presentation to students in a few very small ways. Tweak your examples, and your task sets. The result:

@Naveen Rizvi and I visited Alpha School New York last month. I’ve heard Naveen describe herself as going through ‘an existential crisis’ after seeing it, more than once. Why? open.substack.com/pub/unstoppa...

Expertise-induced blindness is one of the single biggest reasons teachers are baffled by the fact their students do not understand and do not succeed: “Look, all you have to do is copy exactly what I did on the board. What could possibly be difficult about that?”

When students don’t grasp something, we often assume it’s about effort, ability, or attention. But in many cases, the real issue is our instruction. If a process can be interpreted in multiple ways, students will interpret it differently, and some of those interpretations will be wrong by chance.

Fascinating analysis of the work of @krisboulton.bsky.social by @profbeckyallen.bsky.social. I have been spending lots of time on curriculum design and curriculum-making recently, but for teachers at a classroom level this becomes entwined with instructional design. We need more thinking like this.
