M: Hi, Mary. Do you want to start writing a lab report after we finish this experiment?
W: I can’t. In fact, I need to finish early because I’m going over to the Psychology Department to talk to Professor Smith about the job opening.
M: You mean a job on campus?
W: Yeah, and it sounds pretty interesting. It involves helping with her study on learning styles. You know, some people learn best by sight, while others learn best by hearing or touch.
M: Yes. I know that’s her area of expertise.
W: Right! Anyway, for her study, she’s taking some high school students who’re doing very well in the classes and testing them to find out what their learning styles are. Then tutors, people like me, will work with them, presenting materials to them in their particular learning styles.
M: Hey, that is interesting. Now, will you mostly do the testing or the tutoring?
W: Both I hope. I want to be involved from start to finish.
M: Are you going to be paid for this?
W: I’m sure we’ll get something, though probably not much. Anyway, it doesn’t matter to me. I just want to have some hands-on experience.
M: Yeah, and that’ll be nice to help the high school students too.
W: That’s what I thought when I saw the ad. You know you could do it too. You don’t have to be in her classes to work or to study.
M: Really? You have any idea what the schedule is like?
W: Late afternoon and evening for tutoring. I think, after all, the kids have regular classes until 3: 30.
M: Actually that’s perfect for me.
W: Then come along. We’ll save the lab report for later. But[25]we’d better make sure we do a good job on our experiment first.
M: Yeah, first thing’s first.
