What course are the speakers talking about?

M: Hi, Helen. What do you think of our class in children’s literature?
W: It looks pretty good. I was surprised to see you in there. Are you also majoring in elementary education?
M: No, I’m not. But as a psychology major I can use this to fulfill the requirement in developmental psychology.
W: Have you finished the first assignment yet?
M: Not yet. I just brought the books today. How about you?
W: I started this afternoon. It’s great fun reading those children’s stories by Dr. Zuss.
M: Dr. Zuss? I don’t seem to remember seeing his name on the reading list.
W: His full name is Theodore Zuss Gisele. That’s how he is listed in the bibliography Dr. Zuss is his pen name.
M: I loved reading those stories as a child. It would be interesting to read them now from a different perspective. I guess they will give me a good idea of how children think.
W: Those stories are also great for classroom use.
M: How’s that?
W: Well, take a typical Dr. Zuss book like The Cat and the Hat. It has a controlled vocabulary of only 200 words.
M: So that means the children get lots of practice using a small number of words over and over.
W: Exactly. In fact, The Cat and the Hat was written primarily to show how a controlled vocabulary reader could also be interesting and fun.
M: Well. It sounds as if this course is also going to be interesting and fun. I think I’ll get started on those readings tonight.
