I am an adjunct instructor with fellow colleague who "created" the course of instruction we deliver. Basically, he is the lead b/c he has seniority and has been in the institution for a very long time and I am the new guy off the bench. He created the material and since I am the backup/Plan B, he expects me to deliver the same material in the exact same manner (to include the cheesy props he uses). Framkly, the way most of it is laid out does not really flow nor does the embedded media draw relevance to the lesson. I have seen him deliver this material, but for me, a lot of it just doesn't work. What should I do to "personalize" the material without taking any main points away and not upsetting the "silverback?"
