I have been watching some of the videos in the Learning to Teach Online series from the University of New South Wales . The series covers various topics related to online teaching and they are divided into episodes which include a short video plus a PDF. I had some trouble getting the PDFs to download, but the videos played fine for me. I think the Managing your Time video is a good one for new online instructors: Overall, this looks like a good resource.
