Answer:
Studying, even for those who are passionate about learning, is a challenge, it requires effort and it tends to get boring. Even the most fascinating subject taught by the most spectacular teacher might be wasted on those students that are not keen on studying in the first place. That´s why passion and excitement are not only desirable but a professional requirement for anyone who attempts to teach anything. And is not about showing a happy face, but conveying the importance of the subject and its potential in real life. Showing examples and providing different views about the matter, even challenging some ideas, developing critical thinking are all techniques that can be developed with excitement as they offer new possibilities. And students are more likely to respond better and engage in the process of learning if they can see that kind of excitement in the person providing such opportunities. In the end, passion and excitement are sentiments all teachers should have for the teaching act itself, despite the subject.
