Lecture 4 (Butterfly)
1. What is the most likely title for chapter 3 of the text for this class?
CorrectIncorrectNarrator: Listen to a lecture in a biology class. The professor is talking about the compound eye.
Woman: For class today, you should have reviewed the section on compound eyes in Chapter 3 of your text. Yesterday we discussed eye structures called light spots that can only sense light but cannot see images as we do. Today we’ll look at one example of a compound eye by looking at the eye of a monarch butterfly.
Let’s look at the compound eye of the monarch butterfly in this drawing. The compound eye is a very interesting structure. Magnified, the eye looks a bit like a pincushion full of round-headed pins. The surface of the eye is curved and made up of thousands of lenses called ommatidia. Each ommatidium is covered by a six-sided lens.
The curved surface and six-sided lenses allow each ommatidium to face a slightly different direction and sense a slightly different image.|
As light enters each lens, photoreceptors under the lenses send messages to the brain. The brain reconstructs the image of the butterfly’s surroundings by combining the thousands of messages from each of the thousands of lenses into one image.|
Now, we’re going to discuss what a compound eye sees, and I have two points that I would like to make. The first point I’d like to make is that a compound eye can see movement well, but it does not focus well. Butterflies are very nearsighted, yet they are remarkably able to detect movement.|
Have any of you tried to catch a butterfly in flight? Possibly some of you have been frustrated while trying to swat a fly? Researchers have known for a long time that insects of all kinds can sense movement very well. The compound eye allows insects to detect the slightest movement much better than our eye can in spite of the fact that it does not focus well.|
The second point I would like to make is that it is now believed that a compound eye probably sees one image rather than a compound picture. At one time it was thought that a compound eye saw a compound picture. Some thought that monarchs and other insects could detect movement well because each ommatidium registered six complete images, so the monarch saw some 6,000 pictures of the same item. This would be a bit like standing in a store and looking at a wall of TVs all tuned to the same channel. Every movement on the screen produces thousands of like movements.
|Now most researchers think that a compound eye sees one image that is blurred because of the huge number of lenses in the compound eye. Because the eye senses light from so many directions, the butterfly detects movement easily. The slightest movement alters the light sensed in hundreds or thousands of the ommatidia, allowing the butterfly to react quickly, even if it can’t clearly see what it is reacting to.|
Tomorrow we’ll continue our study of eye structures. Please review the section in Chapter 3 about the human eye. I’ve put several interesting articles about recent research on the compound eye on reserve in the library. These articles are considered required reading and will be tested, along with the information in your textbook. Class is dismissed.

Lecture 2 (Complete)
1.What subject does Professor Marquez probably teach?
CorrectNarrator: Listen to a conversation between two students.
Student A: Hi, Tony. Hey . . . I wonder if you could . . . uh, do me a little favor tomorrow afternoon?
Student B: Oh, hi, Alison. Well . . . depends on what the favor is.
Student A: Okay, you know that class I’m taking with Professor Marquez? Well, she’s asked us to try to find some volunteers to . . . uh, well, to take part in a role play . . .
Student B: And so what sort of a role would I have to play?
Student A: Well, you won’t find out until tomorrow. See, we’re learning about focus groups and how they work and how to be a moderator of a focus group. You and the their volunteers from outside our class will be members of the focus groups. The students in my class will take turns being moderators. In real life, there’s only one moderator for each focus group, usually, but Professor Marquez wants every-one to have a chance to play the role of mode tor. Now, since a good focus group has people from different back-grounds, uh, when you come in the classroom tomorrow, Professor Marquez will give you a little card that tells you your vital information: your age, your occupation, how much education you have, that ort of thing . . . and that’s the role you play when you’re pr tending to be in this focus group.
Student B: Tell me a little about focus groups. I mean, I’ve heard of them, but . . .
Student A: All rig t. Well, according to Professor Marquez, there are two basic types. There’s . . . uh, the exploratory group . . . the moderator asks the focus group if a company should arket a new product at all, if there would be any demand for it. Then there’s the experiential group—you’ll be in an experiential group tomorrow. Experiential groups, they try out several versions of a product. People in the group tell the moderator which version of the product they like better. This helps the company decide which one of these versions of the product to market.
Student B: Don’t they use focus groups a lot in Hollywood?
To make movies?
Student A: Yeah, they do. I mean, a movie’s a product, too, and film companies want to know which version of a movie to market. So a lot of times, a director will make several dif-ferent versions of a movie. Usually each version has a different ending. The focus group watches them all and then says which one they like best.
Student B: So, what product will the groups in your class be testing?
Student A: Well, different teams will have different prod-ucts. My team, the three students I’m working with, we’re
. . . uh, pretending that a client company, an imaginary food company came to our marketing agency and said, “We’re thinking about adding a new flavor of ice cream to our product mix, and we’ve come up with a half-dozen recipes for this ice cream flavor, and we want you to help us figure out which of these we should market.”
Student B: Ice cream, huh. So where are you getting the ice cream?
Student A: We’re just gonna buy different brands of the same flavor of ice cream at the supermarket.
Student B: So, you get a grade for this project?
Student A: Yeah, and it’s actually a fairly important part of our total grade. Professor Marquez says that . . . that the chemistry, the uh, interaction between the moderator and the focus group, is key in making sure a focus group goes well. You have to be sure that the people in the group feel free to give their opinions, but you have to keep them on topic. And you want to help the group develop a . . . a group identity, a gr up spirit, you know? But at the same time you don’t want them to fall into the “group think” trap, where the members say things just to be going along with the group . . . being a moderator’s not all that easy, I guess.
Student B: Well, I’m pretty sure I’m free tomorrow after-
- Oh, and . . . uh, what flavor ice cream are we going to be tasting?
Student A: Umm, mint chocolate chip.
Student B: Okay, that settles it . . . I’m in!
Narrator: Now get ready to answer some questions about the conversation. You may use your notes to help you.
