Hi Dale:
You've got a good point and perhaps a principle.
I think when we tell stories to illustrate a point or share a past experience in the work setting, students like these and relate to some of the facts, therefore more likely to remember.
In memory training, they teach to associate something already known with something you want to know. In it's own way, stories, case studies, or past work examples are kind of like that too.
