M: Hi Tracy! What do you think of our class on children’s literature?
W: It looks pretty good. I was surprised to see you in there. [12]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: [13]Have you finished the first assignment yet?
M: Not yet. I just bought the books yesterday. How about you?
W: I started it this afternoon. [13]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: [14]His full name is Theodor Seuss Geisel. That’s how he’s listed in the bibliography. Dr. Seuss is his pen name.
M: I loved reading those stories when I was a child. It’ll be interesting to read them now from a different perspective. I guess they’ll give me a good idea of how children think.
W: [l5]Those stories are also great for classroom use.
M: How’s 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: [15]So that means the children get lots of practice 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 as though this course is also going to be interesting and fun. I’ll get started on those readings tonight.
