Previously I wrote about students not using equals signs properly. So apparently some guys at Texas A&M are getting papers published on this subject, and identifying it as a key way to distinguish between high-functioning and low-functioning math students and national education systems.
Reported is stuff like: "The two researchers suggest using mathematics manipulatives". I disagree. The problem is not lack of manipulatives. The problem is that nobody ever told students what the fucking equals sign means.
I'm semi-convinced that a greater emphasis needs to be paid on the physical syntax and grammar of writing (and as a result, reading) mathematics by students throughout the education system. But that's me.
