ADVENTURES IN SCIENCE
By Nathan K. Chai, '02
With an abundance of enthusiastic demonstration and discovery, a multidisciplinary megacourse satisfies all the general-education science requirements but only whets the curiosity of eager students. IT'S 2:53 on a Friday afternoon, and in a basement classroom in the MARB, R. Paul Evans, '95, assistant professor of molecular biology, is winding down a discussion of genetics. For the uninitiated, his language would seem opaque, as though he were zig-zagging between English and some other language full of long, Latin-flavored words. For their part, the studentsnearly all of them nonscience majorsseem to handle the linguistic calisthenics with ease. They nod knowingly and say things like, "Oh, that's so cool." They don't even flinch when Evans laces consecutive sentences with the phrases RNA polymerase, ribosome catalyzation, and genetic transcription.You can't help but feel impressed by the caliber of these students, many just freshmen. They are, after all, involved in one of the most intense general-education courses offered at BYU. The class, officially titled Honors Colloquium in the Sciences, is a nine-credit-hour honors course that spans two full semesters.Taught by three BYU professors, one professional geologist, several guest lecturers, and a teaching assistant, the class satisfies the general-education requirements for Physical Science 100, Biology 100, and the natural-science elective. It is a fast-moving and eclectic crash course in astronomy, biology, the history of science, mathematics, philosophy, physics, and religion, and most who take itfreshmen or otherwisesay it provides a perspective-changing experience.What's more, these students seem genuinely to enjoy the Herculean workload that comes with the course. Case in point: After the bell rings, students encircle Professor Evans and unload question after question, seeking more fuel for their newly kindled curiosity about genetics. According to many students' watches, the weekend has already begun, yet for more than 10 minutes, Evans is held back by no fewer than 12 still-hungry minds.HONING HABITS OF THOUGHT
Imagine studying with a professor who is an expert in fields as diverse as Renaissance magic and quantum mechanics, cutting-edge genetics and early Greek science, classical languages and contemporary cosmology, geology and mathematics. In effect, students get this amalgamation of scholarship from the instructors who team-teach Colloquium in the Sciences.William E. Dibble, professor of physics, has been with the course the longest. For several years he worked with James L. Farmer, now a professor emeritus of integrative biology, developing the course's pedagogical model, much of which is still used today. Originally, Farmer and Dibble hoped a class that combined two disciplines within one course might provide students with a deeper understanding of the most basic scientific principles and modes of thought.After Farmer retired, Evans eagerly took his place as a course instructor. Around that same time, C. Wilfred Griggs, '66, an archaeologist and a professor of ancient scripture, and professional geologist Otis H. Willoughby, '86, also signed on. The result: a course where nearly any scientific issue is fair game and where concepts and discussions are rarely limited to any single disciplinary approach. It's a course in which students are constantly exposed to competing ideas and radically different scientific theories. In terms of application, this approach means that students might go rock-collecting one day, spend another day among the planets and stars in the planetarium, and find themselves trying to explain mind-twisting physics demonstrations on yet another day."Each faculty member brings his own excitement, insights, and experiences," says Evans, "but our common goal is to demonstrate in everything we do the basic principles of reasoning and understanding, because it's not the facts that are most important. What is most important is that the students learn to use sound reasoning to get from one point to another, so that when an idea is given to them they can envision how someone arrived at that conclusion. Then they can decide on their own whether or not to accept it."Dibble adds that "this class is not usually a matter of 'Here are the answers, remember them,' because in science, the answers change."This dynamic nature of science frees up some of the professors' time with the class: "I never have to worry about rewriting my exams to prevent cheating," Evans quips. "The questions are always the same; it's just that with scientific progress, the answers change."The focus on methods means students can never content themselves with mere memorization or regurgitation of facts. They are instead expected to learn and practice the habits of thought of leading scientistshabits that, when applied, lead to questions, not answers. Genius isn't necessarily knowing how to find the answer, Dibble explains; genius is knowing how to pose questions that will lead to the right answers. And so, he continues, the multidisciplinary approach of the course provides students with not only the setting to develop strong habits of thought but also a wonderful variety of stimulating scientific problems on which they can practice.This unique pedagogy, says Griggs, helps students to be "more informed and be more able to influence the ways science will be used in their lives." He explains that "because much of daily life involves the use of new technologies, the more people can understand the ramifications of the applications of science, the better they will be able to influence and choose those advances which cause the least damage in the world and offer the most benefits."For student Duane M. S. Johnson, '07, the class's focus on strong thinking and questioning, coupled with his in-class association with so many enthusiastic and demanding professors, yielded an invaluable fringe benefit: he gained more confidence. "Before I took this class I wouldn't have asked questions out loud," he explains. "I wouldn't have really cared enough or been brave enough. But in this class you get in the habit of asking every question you can think of and you start to feel comfortable speaking up."Many of Johnson's peers say they experienced similar boosts in confidence and curiosity while in the class. Sarah M. Stewart, '03, for example, shatters stereotypes of today's students when she claims that she enjoyed the intellectual challenge so much that even the tests became fun. "I actually like them," she said near the end of her 200203 experience in the colloquium. "They're very oriented on what you know in terms of how you can apply it to problems. I like that approach."In fact, the students enjoy the course so much that at least one contingent formed a fan club for the professors. After finishing one of Dibble's sections on physics, they prepared T-shirts with Dibble's face on the front and his 10 most quotable lines on the back. A few of the favorites, spouted extemporaneously in class and jotted down in students' notebooks included "You don't want to deny the facts; what you want to do is explain them away"; "You don't have to be smarter than Aristotle to be more right, which means even the dumbest of you may win the Nobel Prize"; and, speaking of quantum physics, "We are now going to explain what nobody understands."AN ADVENTURE AND A DISCIPLINE
According to the professors of Colloquium in the Sciences, if you have to force students to ask questions, you've already lost the game. Instead, the professors strive to put students in situations where their natural curiosity drives them to learn and understand.To do this, Dibble says, you need "a sense of adventure." So, for example, in this class you won't simply chart rock strata and theorize about the laws of superimposition. You will bus around central Utah, where you can hike hidden canyons and look out over mountainous vistas, which, for Willoughby and his students, illustrate the points more clearly than any geology textbook ever could. Or, to take another case, you won't just talk about physical laws, you will see them in actionwhich, in this class, means seeing Dibble in action.Dibble's physical demonstrations are the stuff of folklore. On any given day, you'll find him at the front of the class, an amused grin painted on his face, firing off bolts of static electricity; or launching metal rings from an electromagnet, across the quad, to a student wearing a catcher's mitt; or choreographing amazing chemical reactions with all the enthusiasm of a child using his first chemistry set. He is as much a performer as he is a teacher. Given that the class is designed primarily for students whose academic fields lie outside the sciences, this talent becomes an invaluable asset.At least one time, however, Dibble's sense of adventure and eagerness to rouse his students' dormant curiosity got the better of him, according to students. Kelli K. Thomas, '06, tells the story this way: "Professor Dibble was trying to demonstrate spontaneous combustion, and he says, 'I think I added too much of that chemical.' But then he's like, 'Oh well.' So he adds this other chemical and all of a sudden the whole thing explodes, and his tie and suit coat catch on fire. He's running around the room trying to get the flames out, and we're just sitting in our seats laughing 'cause we don't know what to do. He didn't wear a tie or suit coat for a week."Dibble shrugs it all off as rumor. "They claim I set fire to my shirt once, but I didn't. I may have set fire to my notes, but I think the rest is just legend. For one thing, I don't have any shirts with burn marks. I have several that are ripped or discolored, but none with burns."Not to be outdone, Evans also has his ways of keeping students alert and interested. During a demonstration with liquid nitrogen, for example, Evans will slip a hot dog into his glove in place of his forefinger. After freezing and shattering a racquetball and a flower, he suddenly dips his finger into the liquid, puts it down on the table, and brings down the hammer. The hot-dog finger and glove shatter, and students scream. Evans laughs diabolically and holds up his hand; slowly, his still-intact finger squirms out of the ragged tear in the glove.If they do nothing else, these in-class performances serve one key function: they help students remember that science can be both an adventure and a discipline, that teachers can be both intelligent and personable, and that learning can be a whole lot of fun.Of course, the fun and learning are not always planned. In Colloquium in the Sciences, opportunities to learn and apply class concepts can be found anywhereeven in mishaps like the one that occurred on a geology field trip to Utah's San Rafael Swell in 2000.The tour bus dropped the students and professors at a trailhead near a hidden canyon several miles from the nearest paved road and about 45 miles from the nearest town. Willoughby then led the students on a geology hike up the canyon, indicating the different strata of rock, asking students to offer theories on the conditions that caused their formations, and pointing out that they were, quite literally, walking through millions of years of natural history. The students even spent some time studying, with Professor Griggs' help, several Anasazi rock paintings on a sandstone wall.When the group returned to the bus in the early afternoon, they met with a startling discovery. While trying to turn the vehicle around, the driver had somehow high-centered the bus and buried the wheels axle-deep in fine red sand. Evans saw an opportunity to reinforce the scientific method in the minds of his students. After a group prayer, the students began to try various experiments, or as Evans laughingly puts it, "to invoke every physical principle they could think of that might help us get out."Eventually, after testing several hypotheses about how best to move the bus and learning from the failures, the group came to a viable solution. They'd already discovered that the tires couldn't grip the flat shale stone, so with a pile of pebbles ready, they began to rock the bus back and forth, the motion opening gaps between the tires and the surrounding sand, which then allowed them to pour the pebbles in around the tires. With each push back and forth and each new pebble dropped beneath the wheels, they raised the bus, inch by inch, up to surface level. Using a scientific model of experimentation, sound reasoning, and a pile of pebbles, they were able to raise a several-ton bus out of nearly a foot and a half of sand and get it back on the road again.Though they didn't know it at the time, the students that day passed Evans' most important test: without any help from the professors, they'd approached a difficult real-world challenge using the scientific skills learned and modeled in class. And, just as importantly, they did it with the confidence that, if they posed the right questions, eventually they'd solve the problem.A STATE OF CONSTANT FASCINATIONThree days after Evans' lecture on genetics, the students return to class full of questions and eager to begin work on a project dealing with glow-in-the-dark bacteria. When Evans reminds the students of an upcoming exam, no one complains. Instead, they spend a few moments coordinating out-of-class study groups and donations for pizza delivery.In a typical year a few of the students may switch their majors to the sciences. Others search the bookstore and the library for more information on scientific areas of interest. Nearly all of them recommend the course to roommates and friends.It is just as the professors of Colloquium in the Sciences hope it will be."We want the light inside them to grow brighter," Evans explains. "Whatever excitement students have about learning should be increased as a result of the class experience."Dibble hopes the course helps students "see more in the world around them, so that they come to live in a state of constant fascination."
