I find that when people think they are beyond the Scrum basics, they are not. It like saying you know how to dribble the basketball and therefore you no longer need to practice dribbling. Whatever you know today, you must work to keep it. It is not yours and can be lost. That’s the price of having plastic minds, they can change and sometimes too easily. 

Again::
If you believe that you are done learning from the scrum framework, you are missing something.
It will never stop revealing new information to you when you pay attention. So, use the framework in the course to guide discussion and detect when you need to change. Then as an opportunity to change happens during the course(my experience is that it always does), point out that you just applied it to the course, changed and you still learn as well. The course then becomes a complex adaptive system that is exploring the scrum framework and how it can be used to reveal / address new information.
BTW – This means you will have to admit that each course is unique and you don’t have all the answers. At least you can use the framework to help detect the right questions and sometimes to provide good answers as well but, not always :)
My students have long ago stopped complaining that the course is too basic. Give’em hell, don’t spoon feed and don’t pretend to have all the answers. Simply explore whatever their heads and yours is capable of. dialog dialog dialog
