I've had a tab open for a while containing an Inside Higher Ed article on a new approach to introducing science at Emory University:
David Lynn, who chairs the department of chemistry at Emory University, spoke about Emory's seminar program for entering freshmen. All Emory freshmen must take a seminar the first semester and the one for math and science teaches students how to think like a scientist.
The course consists of five modules. Each module is taught by a grad student who presents his own research, guiding students through the research process, from designing studies to defending results. For the final, students must write and defend a proposed project.
The article mostly talks about the effect of the course in terms of teaching the grad students how to teach, but I flagged it because I want to say something about how it affects the undergraduates. It's been sitting there un-commented-on for the past week, though, in large part because I've been teaching our own first-year seminar class.
We've been doing something similar for entering students with an interest in physics for eight or ten years, now, and from the undergraduate perspective, it's kind of a mixed bag.
(Continued below the fold.)
The structure of our course is similar in some respects to the Emory class. We invite first-year students who have expressed an interest in physics to take the class, and five faculty each give a series of lectures about a topic relating to their research. I talk about laser cooling, one of the astrophysicists talks about black holes, our chairman talks about nuclear and particle physics and does a Rutherford back-scattering lab using the accelerator.
The transparent goal here is to expose the students to the most interesting and exciting stuff we know about in their first term, to get them interested in physics and astronomy, and hopefully draw them in as majors. We do it this way because the first couple of terms of introductory physics tend to be kind of a hard slog, and we hope that presenting some more interesting material up front will provide an incentive to stick with physics.
As I said, this class has been going on for a while now, and it's kind of a mixed bag. On the positive side, we've seen a dramatic increase in the number of physics majors over that span-- six or eight years ago, it wasn't unusual to have one, two, or even no physics majors in a graduating class. Last year we had eight, this year we have thirteen, next year we expect another ten or twelve. Many of those students entered the department through the seminar class.
On the other hand, though, some of the students have had very negative things to say about the class, mostly due to the pace. We're on a trimester system, with ten-week terms, so five sets of faculty lectures means we each get two weeks. I'm trying to discuss laser cooling, atomic clocks, and Bose-Einstein Condensation in a total of six lectures. We end up throwing a huge amount of material at the students very quickly, and some of them end up feeling overwhelmed. One or two of our majors told me they hated that class, because it moved so quickly.
So, as I said, a mixed bag. I really enjoy giving the laser cooling lectures, but I'm not sure how much the students really retain from them, other than that it's fun to smash stuff with liquid nitrogen. It has been an effective recruiting tool, though-- I get much more interest in summer research jobs from students who have taken that class-- so I wouldn't want to get rid of it, but maybe it needs some tinkering.
The problem is really the ten-week term. The Emory class seems like it probably has more of an overarching theme or structure to it, which would probably help matters, but I'm just not sure we would have time to do that, unless we cut down the number of faculty to a point where we wouldn't be able to present a representative range of topics. It's an interesting idea, but I'm not sure that what w're doing now is broken badly enough to require major repair efforts.

SRO first lecture. Lecturer fills party balloon with hydrogen, ties off with length of string, attaches to ringstand. Meterstick with candle on end is ignited. Lecturer stands back, room lights are extinguished.
"This is Case I." Ignites balloon. Lecture hall hears "Pop!" and sees lame fireball. Turn on room lights.
Lecturer fills party balloon with 1/3 oxygen 2/3 hydrogen by volume, ties off with length of string, attaches to ringstand. Lecturer puts in ballistic earplugs, adds heavy motorcycle helmet with faceshield down. Meterstick with candle on end is ignited. Lecturer stands waaaay back, room lights are extinguished.
"This is Case II." Detonates balloon. (Be careful that the balloon is not near a blackboard or wall to avoid damage. Make it a small balloon.)
"Life will unendingly hand you Case II. Case II is blunted into Case I with mathematics and the scientific method. If a god will intercede, this will only occur post-mortem."
I've heard similar complaints about a graduate class. This was a nano class, where it was team taught by a number of people. Each person came in for a couple of weeks. The students complained that each prof layed on a lot of work without seeming to be aware of what all of the other profs had done or would do in previous and subsequent weeks.
Now, yeah, you should work hard in a grad class, but when something is that chopped up it does lend itself to each thing trying to overfill the space available.
One solution would be to seriuosly limit what each of you do. It's hard to hold onesself to this, since there are too many cool things, and it also wouldn't expose students to as much... but why not pick one of your three topics, instead of all three, to cover in your two weeks? And, likewise for other faculty in the class. Would that work?

The problem would really be in getting everyone to agree to that, and hold to it. And I'm not sure the class is really broken badly enough to get people to go along with a major restructuring effort-- I don't think we're scaring away anyone who was thinking about majoring in physics, we just aren't drawing them in as effectively as we might.
I do think it helps in some regards. In years when I've taught the first-year seminar class, I've had an easy time finding students to work in my research lab. Students from the class know me a little, and know enough about what I do to be interested in working for me. Years when I haven't taught the class, I've had to beat the bushes a bit to find students.
I expect that we'll be changing away from our ten-week trimester calendar at some point in the next few years, and if I'm still here when that happens, I'll lobby for re-working the class to have more of an overarching theme. For now, I'm just going to keep doing what I'm doing. The next time I would have a chance to teach the class isn't until Fall 2008, anyway (if I get tenure, I'll be on sabbatical next fall).
