Hi Ruth:
I think it's true teachers have their favorite and less favored topics. It ought to be a balanced combination of delievry techniques and a variety of instructional methods whether the teacher prefers them or not.
One thing we all have in common is the ability to be honest, caring, sincere, genuine - natural versions of ourselves rather than an artificial version of some else in order to try to capture student attention. Students appreciate honesty more than personalty.
