Mathematics Educators Stack Exchange (MESE) is a question and answer site for those involved in the field of teaching mathematics.
The community welcomes questions on teaching mathematics and the process of learning mathematics at all levels. From questions about helping children to appreciate numbers to suggestions on the advisement of doctoral students conducting original research, a broad spectrum of questions about mathematics education is admissible.
In particular, both questions on research in mathematics education and questions seeking hands-on advice are welcome.
Please note, however, that your question should be about mathematics education as contrasted with one strictly about mathematics. If you are interested in asking a mathematical question instead, that's great; but please do not ask it here. Instead, note that there is a very active community at Mathematics Stack Exchange (MSE) that answers mathematical questions at all levels (provided they are presented well; please see their FAQ for details).
I am a mathematics teacher and have a question related to my teaching, but it is not specific to mathematics. Can I ask this here?
The community welcomes general questions related to teaching provided that they are relevant to teaching mathematics. However, there is also an Academia Stack Exchange for questions about academic life more generally. You may wish to consider if your question fits better there.
I want to do a presentation using LaTeX / Mathematica / Powerpoint etc for my class and have a question related to this. Can I ask this here here?
It depends. If your question is about the pedagogical aspects of using computer presentations (or something of a similar nature) then this is on-topic here. If, however, you are facing a technical problem using the software, then you might consider the TeX Stack Exchange site or the Mathematica Stack Exchange site. Additionally, Powerpoint questions and various other computer related queries can be on-topic on the Stack Exchange site Super User (as always, please see the sites' respective FAQs before asking).
I am not a teacher but I still have a question about teaching or learning mathematics. Can I ask this here?
Absolutely: You are welcome to contribute to the site. There are no formal requirements for asking, answering, or generally participating here. Please note, though, that the site is not for questions solely on mathematics itself, but rather for questions on teaching mathematics and the process of learning mathematics. As stated earlier, mathematics questions may be a better fit on Mathematics Stack Exchange.
If your question is not specifically on-topic for Mathematics Educators Stack Exchange, it may be on topic for another Stack Exchange site. If no site currently exists that will accept your question, you may commit to or propose a new site at Area 51, the place where new Stack Exchange communities are democratically created.
