This morning we had three IDC (instructor development course) candidates in the pool who were doing teaching presentations. Some of the candidates presented their topics with great skill and confidence. However, as in most of these courses we had one candidate that just did not present his topic with any confidence.
I understand that it is difficult presenting to a group of instructors and your peers, but consider what it will be like presenting to a group of new students. What we need to remember as instructors that a lot of what students learn is from the non-verbal communication as much as from the verbal communication. Some people say that a lot more is "caught rather than taught". How true this is I do not know, but I do know that when we teach a class we should convey the information with confidence and enthusiasm.
If the instructor is half-hearted then the students will tune him/her out and I bet that you will have a lot more problems/challenges with the students. If the instructor is not enthusiastic/passionate about the class, how can we expect the students to be? I believe it is up to the instructor to set the pace and lead by example.
Another pet-peeve of mine is when candidates perform skill demonstrations half-heartedly. No matter how many times we tell some candidates that the skills should be demonstrated at presentation quality level, it seems that they just perform the skill to get it done. For example, in the mask remove and replace skill, I look for the candidate to first flood the mask and pause a second before removing the mask from his/her face. It is a subtle thing, but I feel that if they make the skill look easy then the students will be able follow what the instructor is doing and perform the skill correctly.
Instructor Candidates should remember that you need to model good skill demonstration abilities to your future students. Say it with pride, say it like you mean it and perform your skill demonstrations with style and exaggeration.
