Marygrove College offers a masters in the art of teaching through its
distance learning program. It is a good program for learning teaching
strategies. I've been through the program and am currently a mentor. Its
advantage is that you can view the videos anytime, you never have to travel
to the campus , you can complete it in 5 semesters and you don't have to
write a thesis and its useful.
I'd be glad to give you any information from my personal experience or
