Lynda.com is one of the better providers of digital training on all sorts of topics, ranging from photography to marketing to design to technical topics like programming and instructional design. They have courses, learning paths, and individual lessons. A full membership is several hundred dollars per year.
I just found out this weekend that Hennepin County Library users get free accounts with full access.
I could see this being useful for teachers wanting to pick up new skills or for students looking to learn specific skills that we might not have solid curriculum for yet.
