W: I can't. In fact I need to finish it earlier because I'm going over to the psychology department to talk to Professor Smith about a job opening.
M: You mean a job on campus?
W: Yeah. And it sounds pretty interesting. It involves helping with her study on learning style. You know, about how some people learn best by sight, while others learn best by hearing or touch.
M: Yeah. I know that's her area of expertise.
W: Right. Anyway for her study she's taking some high school students who aren't doing very well in their classes and testing them to find out what their learning styles are. Then tutors, people like me, will work with them presenting material to them in their particular learning style.
M: Hey. That is interesting. Are you getting 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 it'll be nice to help those 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 on the study.
M: Really? Do you have any idea what the schedule is like?
W: Late afternoon and evening for tutoring I think. After all, the kids are in regular classes until three-thirty.
M: Actually that's perfect for me.
W: Then come along. We will save the lab report for later. But we'd better make sure we do a good job on our experiment first.
M: Yeah. First things flint.
