You started with your classroom example and then continued with corporate training as the playground for storytelling. Everything or nearly everything you write here is applicable to classroom teaching, particularly with college level classes. More so because these students will transfer to corporate when they graduate and find jobs.

The take from here I suppose is to find ways to transfer ideas to stories to be used in classroom settings to engage learners. In my own teaching of epidemiology, I have found that when I related to stories/experiences about our epidemic/disease investigations, students really seemed interested and asked questions, got engaged. On the other hand, on those occasions I used dry theory on the same topic same theme same setting, the class would be marked by a few yawns. Storytelling does seem superior to slideshow in a classroom setting but the question is about how to adopt, where to use, and how to create those stories. Also, if you are conducting say a workshop, how can we best integrate storytelling there where participants enjoy listening and working at the same time?
