Kurt van Lehn - Mind Bugs: The Origins of Procedural Misconceptions

I don't know if I like the title better than the abstract:

As children acquire arithmetic skills, they often develop "bugs" - small, local misconceptions that cause systematic errors. Mind Bugs combines a novel cognitive simulation process with careful hypothesis testing to explore how mathematics students acquire procedural skills in instructional settings, focusing in particular on these procedural misconceptions and what they reveal about the learning process.

Btw, I thought "misconceptions" were necessarily declarative.

(reminds me of the idea of a system to support formalization)

Douglas Engelbart seems to have been a pioneer of Intelligence Augmentation. He wrote "Augmenting Human Intellect: A Conceptual Framework". He also invented the computer mouse.
