Answer:
Vicarious (experiences).
Step-by-step explanation:
This type of experience refers to seeing another person do or repeat a behaviour, like in the example. This, if the person that looked at the behaviour has features in common (in the example both of them are teachers) will boost self-efficacy and confidence to repeat the behaviour. As in the example: teacher A does X. Teacher B sees it, and thinks he can as well. As both of them are teachers, teachers B relies on this vicarious experience to try and do the same as teacher A.
