I've been teaching for a while, by a while I mean over 2 decades, and many of my students are going into education or have gone into education. I also teach the public history course; practicing public history is often a form of teaching. With the usual caveat that this list isn't comprehensive and isn't a substitution for a systematic study of education here are some teaching resources that are useful.
