I wonder how many instructors update or simply recycle the stories from personal experiences that are shared with a class.
My students know me to be a storyteller. I have to remind myself that new groups of students have not shared my experiences and so the information is new and instructive to them.
I also share current or relevant case studies that are not mine but apply to the topic of discussion.
I think effective storytelling enhances the instructor's credibility, and therefore effectiveness, with the students.
