This site is - as far as I'm aware - for what I would term working maths educators. That is, on the whole the users of this site are not researchers in mathematics education. Rather, we are the people who get on with the work of providing mathematics education every day.
That said, there are some people out there who do actual research on mathematics education. There are more who study education in general. I have a hope that some of the results of this would be useful to people like me, but I find it hard to get hold of stuff that I can directly use. In particular, what I want is ideas on how to improve my teaching that:
Are based on actual research. That is, its effectiveness has been proved. (Of course, this might be that it has been proved to be effective in teaching Australian Skiers how to do Differential Topology, but that's still better than "It sounds like a good idea so let's give it a try.")
Are practical. I've heard my fair share of general theories of learning and education and general theories are not all that useful to me because it takes time to translate them in to things that I can actually do in my lecture hall. Moreover, the opportunities for experiment are somewhat limited because if I get it wrong, the students tend not to come back for a second attempt.
Are mathematical. Here the problem is that many techniques are subject-specific and what works well in a history class or philosophy class may not be so good in maths ("Get in to groups of three and discuss the Gauss Elimination Algorithm.").
What I'm looking for is a way in to the maths education literature. I don't really want to start reading random articles because I don't have the necessary background to evaluate them. Maybe eventually I'll get to that level, but for the moment I need some guidance. However, although short of time and expertise, I do have a reasonable level of intelligence and motivation so I think that if someone could provide me with a road map then I'd do a reasonable job of finding my way from that.
Note that I don't want a list of all maths education departments or journals. I want a recommended initial reading list. But also that should be knit to practice since I don't want to become a maths education researcher myself, just that I want to make use of the fact that they exist.
So, where do I start reading?
