The tag pedagogy gets a lot of usage, possibly too much. I propose a discussion to sharpen the meaning of this tag (or to replace it by more specific ones).
The current tag wiki says:
Pedagogy questions ask how to help students learn something.
This seems so broad, it makes it almost empty.
I agree that this tag is used very broadly, and that there is a variety of types of questions which uses this tag. The following list is not intended to be complet, but tries to classify the zoo of questions we have.
Questions which are concered with course design, like On the use of calculators in elementary/high school? Computer algebra systems later on? and Why teach back substitution with row reduction?. These questions about a certain method or technique and ask about the pedagogical implications of this, including the how and the why. I'd rather call these didactical questions than pedagogical ones.
Questions which ask about the teacher-student interaction in a specific situation, such as Teaching somebody else's class. Imho, these kind of questions are the ones which fit best into this category.
Meta-questions concerned with pedagogics itself like Is there a tag/competence classification for mathematics education?.
I vote for removing the tag altogether in favor of more specific tags. Pretty much every question about education could easily be construed as having to do with pedagogy.
Update: I am about to start implementing this. Please speak up in case of objections, better ideas, and so on.
I propose the creation of one or two somewhat general tags to be used for some of the questions now tagged pedagogy:
general-pedagoy: for questions touching upon pedagogical considerations and problems of a general nature, i.e., not specific to mathematics. Please note that some aspect of the question should still be related to mathematics.
mathematical-pedagogy: for questions on general considerations and problems of teaching mathematics, i.e., issues specfic to teaching mathematics yet relevant to various contexts and courses.
Maybe one, then named general-pedagogy, could suffice with a slightly broader description then. But at the moment I am leaning towards having both.
None of them should be used too freqently, but only if it is really a rather general question.
