Formal pedagogical knowledge
Many universities now recognise that tertiary academic teaching can be taught as a scholarly subject. There is a growing body of research on the subject. 

Similarly, tertiary institutions recognise that there has generally not been a requirement for academics (usually research-focused) to demonstrate any ability in teaching, nor are they exposed to any opportunities for training.

For this reason, many institutions (in the UK and Commonwealth, at least) offer a post-graduate diploma or certificate in Academic Practice. In such a course -- usually attended by research academics with a teaching component to their work -- students are exposed to current pedagogical theories. 

My institution offers such a PGCert, and I am working my way through it now, with the support of my HoD. It's been pretty good, so far. See if your institution offers such a degree. 

Bear in mind, I've seen this strategy -- institutions offering PGCerts in academic practice -- done very badly. Namely, staff are required to take the course, and pass. In the worst case, the quality of the teaching was poor.

I am pleased to say, that at my present institution, the teaching on the PGCert has been very good, the readings helpful, the exercises relevant. Your mileage may vary.

With respect to resources, I am generating an annotated bibliography of the readings (journal articles, books, etc) that we have been recommended for this course. If you are interested in this, I can share the link with you.
