Answer:
He is using front-stage behaviors in the classroom and back-stage behaviors with his friends.
Explanation:
People have different roles to act out throughout their daily lives thereby making them to display different kinds of behaviour depending on which situation they find themselves in
A lot of people, without necessarily observing themselves consciously or unconsciously, behave differently as their professional selves versus their private or intimate selves.
Front stage behaviour is normally utilize when people know that others are watching them. How people participate in a front stage performance can be highly intentional and purposeful, or it can be habitual or subconscious. Front stage behavior follows a structured routine and learned social script shaped by cultural norms. Waiting in line at the bank, boarding an flight and flashing a transit pass, and exchanging pleasantries about the weekend with colleagues are all examples of highly structure routines and scripted front-stage performances.
The routines of people's daily lives—traveling to and from work, shopping, dining out, or going to a cultural exhibit or performance—all fall into the category of front stage behavior. The "performances" people put on with those around them follow familiar rules and expectations for what they should do and talk about with one another in each setting. People also engage in front stage behavior in less public places such lecturers among students in the classroom as in the case of Professor Smith. He relises he is being watched by students as an example so he puts up a front stage behaviour.
When people engage in back stage behavior they are more relaxed and comfortable they let their guard down and behave in ways that reflect their "true" selves. They cast off elements of their appearance required for a front stage performance, such as swapping work clothes for casual clothes and loungewear. They may even change how they speak and comport their bodies or carry themselves. This is the case of Prfessor Smith and his friends he doesnt have to put up a front, he basically is his real self
