Re: Mathematics education on the arXiv?

"The problem "math educators" face is entirely different: mathematical thinking is about establishing the truth or falsehood of a statement." # To me, that's a bit myopic. I'll take "mathematical thinking" to be about the internal development of (what amounts to) a personal mathematical "theory" ... perhaps as guided by teachings from others. The logic of statements surely is of concern, especially at the higher levels of such theorizing. But without the processes of theorizing, the statements have little substance. Agreed: "... the goal of a math class is to get the students to learn establishing whether or not things make sense and to insist on things having to make sense. " And that means learning how to theorize, well.
>>E,g, "identify at least 3 kinds of triangle and at least 3 *pertinent* kinds of nontriangles"? "This is exactly the kind of things that is killing mathematics in the mind of people."
Once again, we are talking in two very different contexts. True, as an instructional tool, a particular exercise of that kind has a very limited purpose and, for students, may seem to be only a perfunctory challenge. But regarding tools for mathematical learning, the student (or teacher) who cannot surface examples and contraexamples of a mathematical concept or conclusion has little or no conceptual meaning for it ... and has not internally reabstracted in order to own it ... and is left with only superficial formal knowledge, thereof.
For sure, the Mathematical Knowledge for Teachers' Education must include knowing the mathematical roles of examples and counterexamples. [Just think about the discussions that go on in graduate mathematics courses!] Moreover, I am certain that good research can readily disclose that students or teachers who master the art of examples/counterexamples benefit, thereby, even among young children.
Cordially, Clyde
