Cognitive and behavioral phenomena
Names of the phenomena connected with learning and doing mathematics.
Examples: mental representation, malrule, reification. Much of this (but not all) is terminology from cognitive science or mathematical education community. It is my belief that many of these words should become part of mathematicians' everyday informal jargon. The entries attitudes, behaviors, and myths list phenomena for which I have not been clever enough to find or invent names.
Note: The use of the name "jargon" follows [Raymond, 1991]. This is not the usual meaning in linguistics, which in our case would refer to the technical vocabulary of mathematics.
