M: Hi, Emily, what do you think of our class in Children’s Literature?
W: It looks pretty good. Are you also majoring in Elementary Education?
M: Yes, I can use this to fulfill the requirement in my course.
W: Have you finished the first assignment yet?
M: Not yet, I just bought the book today. How about you?
W: I started this afternoon. It’s great fun reading those wonderful children stories by Doctor Brown.
M: Doctor Brown? I don’t remember seeing his name on the reading list.
W: His full name is Jonathan Brown Smith. You can find this name on the reading list. Doctor Brown is his pen name.
M: I love reading those stories as a child. It’ll be interesting to read them now from a different point of view. I guess they’ll give me a good idea of how children think.
W: Those stories are also great for classroom use.
M: How is that?
W: Well, take a typical Doctor Brown’s book like The Cat in the Hat. It has a controlled vocabulary of only two hundred 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 in the Hat was written mainly to show how a controlled vocabulary reader could also be interesting and fun.
M: It sounds as though this course is also going to be interesting and fun. I think I’ll get started on those readings tonight.
