M: Hi, Helen, what do you think of our class in children’s literature?
W: It’s pretty good. I was surprised to see you 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 bought the books today. How about you?
W: I started this afternoon. It’s great fun reading those wonderful children’s stories by Dr. Seuss.
M: Dr. Seuss? I don’t remember seeing his name on the reading list.
W: His full name is Theodor Seuss Geisel. That’s how it’s listed in the bibliography. Dr. Seuss is his pen name.
M: I loved reading those stories as a child. It’ll be interesting to read them now from a different perspective. I guess it’ll give me a good idea about how children think.
W: Those stories are also great for classroom use.
M: How is that?
W: Well, take a typical Dr. Seuss’ book like The Cat in the Hat. It has a controlled vocabulary of only 200 words.
M: So that means the children get lots of practice in using a small number of words over and over.
W: Exactly. In fact, The Cat in the Hat was written primarily to show how a controlled vocabulary reader could also be interesting and fun.
M: Well, it sounds that all these courses are going to be interesting and fun. I think I’ll get started on this reading list tonight.
