I’ve come across some excellent resources tonight for teaching digital storytelling.
A great introduction to why we tell stories can be found on the Call of Story website. The site is geared more towrds a revivial of verbal, live storytelling, but the information about storytelling in general is great to get new digital storytellers thinking.
I also found great materials on this website made by Kevin Hodgson for the Western Massachusetts Writing Project. The site includes a detailed tutorial on how to use MovieMaker to make a digital story, sample storyboards, an assessment marking rubric, and more.
