W: OK, John, you were saying that you taught writing in America, and you said it was a paperless class.
M: Yeah. Paperless class.
W: OK. What does that mean, a paperless class?
M: Basically,(5)it means that we didn’t use paper. The students sent their assignments through e-mail, and I would do all the grading online.
W: OK. Did you like it as a teacher?
M: It was a bit difficult at first, because it took a lot to get used to reading everything on the screen. (6)But once you get in the habit of doing it. it’s easier for you because you can just highlight something by making it red and the like with the mouse.
W: Did the students like it?
M: Most of the students did, but a small majority who were usually late delivering their homework didn’t. (7)They wanted to just slip their paper under my door so that I wouldn’t know if they were late. But with a paperless class, they had to log in at the time they sent their paper to me. You know, the computer doesn’t lie. I would know if their paper was late.
W: So, you’re a writer, do you think it actually helps students to do this stuff on computers or should they go back to the pencil-paper method?
M: I think it is important to be able to do both. I think that the most important thing about being a writer is being able to be versatile and go in different directions and write in different forms, but probably as far as tools go these days,(8)it’s more important for students to be able to compose on a computer, because most likely that is how they’ll be doing most of their writing.
