Hello: I have been teaching for a few years now. I try to have a little lecture and some role playing along with some short video or other resources to help support the concept. This allows students to stay active and to play a role in their own learning. Empowering the students goes a long way in the classroom. To much lecture they loose interest to much role paly the will get away from the concept being presented. To much video they will not comprehend the concept--they also look at it as if the instructor is letting someone else do their job. It takes some time in the classroom to find this balance. But it is a learning process for everyone. This is where getting to know your class will help. Each set of students are differnet I have found what I can do in one class does not always transfer to another class.
