Hi Pete,
That is setting the stage for a successful class. The students know you are excited about having them in class and that each student will be supported in his/her learning.

Meet and greet them at the door or in the hall way. Show that you are excited to see them and welcome them to the course and say the name of the course as they walk in.Shake hands, learners will feed on the positive energy you project.
I agree. Confidence exudes professionalism and preparation to teach the course. Students also recognize when an instructor is self-confident.
A key way of developing positive energy both personally and professionally.
