I think one of the biggest challenges I find as a teacher is after I explain a task and I view all the heads nodding in agreement, shortly thereafter I am baffled as I watch half of them doing something completely different. It seems to be the younger students (18-23). I jokingly ask them if when they here me speak, do I sound like the teacher from Charlie Brown/Peanuts? It is frustrating because in the Culinary World, if you are unable to take direction and do exactly what is asked of you, you are destined to fail.
