As teachers and learners we know that "every one of us has a story to tell." Digital storytelling allows someone to use multimedia (text, images, video, sound) to report on a historical event, explain an important time in ones own life, investigate a complex situation or event.
The Center for Digital Storytelling - Cookbook (http://www.storycenter.org/cookbook.html) includes several examples of story types that you are commonly including. Certainly these types of stories are not applicable to all disciplines.
The Story about what I Do
About a Place in My Life
