Modeling behavior is an important part of the instructional style of an instructor. I have had students come on the first day of class in attire that was far from professional, speaking in slang, hygiene not acceptable and using profanity.
The second day of class I came into class in ripped and dirty clothes, my hair all over, chomping on gum, dirty hands and face, and an overall appearance of "a mess". The students sat there in awe.
As they say, "a picture, or in this case a visual, was worth more than a 1000 words". I then explained how their outward appearance has to be professional if they want to succeed in a profession.
I asked them to write down what they thought of me and my appearance while I changed into my professional attire. We discussed how their attitude changed towards me. It was an eye-opener for most of them and it changed some attitudes rather quickly.
Does anyone have any good ways they have used modeling?
