Jason,
Stories are good to illustrate a point. Unless the class is about "storytelling", these behold asset and augment, not occupy the presentation. Stories are great to introduce a subject, provide an application of a work situation, or help clarify some difficult concept. Students appreciate stories because usually there is something there they can relate to. So, we are actually taking something they already know and merging it with something we want them to know.
