W: Teaching is a whole new ball of wax for me.(9)I’m not sure how I should approach my subject.
M: I know how you’re feeling. I felt the same way when I first started teaching. You are teaching history, aren’t you?
W: Yes.(10)I want my students to learn the subject, but I would also like them to enjoy the process. How do I do that? I know I had teachers in the past that were boring and all I did was to go to sleep. I had others that made the subject live for me. Looking back now, I’m not sure how they did it.
M: I think you will find that those teachers whose classes you enjoyed were those who loved the subject they were teaching.
W: You’re right.(11)I remember Mr. Donner, my accounting teacher. I was sure that was going to be the most boring class of the year but it wasn’t. He came to the classroom the first day and told us, "You are here because you have to be here. I’m here because I love it!"
M: That’s what I mean. If the teacher really enjoys the process of teaching, the students will most likely enjoy the class and learn more.
W: I really do enjoy history, so I guess I should relax and help the students enjoy it.
M:(12)It helps to have a comfortable physical environment, but the most important thing is to have a mentally stimulating environment. It doesn’t hurt to tell a joke or two to get the students in relaxed and interested frame of mind.
