Teaching about ethics and other sources of controversy in science class.

In a post about curricular issues in genetics and biochemistry courses, Larry Moran raises some good questions:

It’s almost a requirement these days that introductory genetics courses include a section on genetically modified crops. This invariably leads to tutorials, or labs, or essays, about whether GM-foods are a good thing or not. These discussions are usually lots of fun and the students enjoy this part of the course. Professors are convinced they are teaching ethics and that it’s a good thing to show students that ethics is an important part of science.
In introductory biochemistry courses we often have a section on fuel metabolism. That’s the part of biochemistry that deals specifically with how your food is converted to energy. It’s human biochemistry. In that section of the course the Professor often raises the question of proper diet. Is it okay to eat meat? Are trans fatty acids bad for you? Should you be eating carbohydrates? Our experience is that Professors who teach this section often have very strong opinions and their personal ethical stance is portrayed as scientific fact.
These are two different cases. In the first one, the question is whether the value of debating controversial “ethical” issues outweighs the disadvantages. The biggest downside, in my opinion, is the emphasis on technology as opposed to pure basic science. By giving prominence to “ethical” issues we are emphasizing the consequences of genetic knowledge as it relates to the human condition. …
Part of the problem arises from a desire to please the students. How often do we hear the complaint that students aren’t interested in biochemistry and genetics? The students are bored by science so we have to add sections on genetically modified foods and genetic screening to our introductory genetics courses. Isn’t this strange? Rather than concentrate on making the basic science as interesting and exciting as possible, we cater to the students by giving them the topics they think are interesting. That’s no way to educate.
There’s another problem; what is ethics? Sometimes it’s hard to see the difference between simple controversy and ethics. Sometimes it’s hard to define exactly what “ethics” is all about in spite of the fact that “bioethics” is one of the biggest growth industries in science. Here’s where a philosopher or two could weigh in.

Hey, I’m a philosopher! Here’s my take:

Best final exam doodle EVER!

I’m sure I’m not the only academic who receives final exams with doodles (as well as “thank you for the class” and “please don’t fail me!” messages). But I need to share a piece of exam artwork that transcends the bounds of doodling.

Indeed, it is a cartoon illustration that demonstrates good mastery of the concept about which the student was asked on that exam page. (In addition to the drawing, the student presented a perfectly correct and crystal clear written answer to the question. The drawing was an added bonus.)

Let me set up the cartoon with a brief explanation of the question so you can fully appreciate how wonderful it is:

What part of ‘course requirement’ isn’t clear?

On my last post, Kristine commented:

My favorite “finals week activity” was defending to two students why they couldn’t take the lab exams three weeks after all of their classmates took it, just because they realized now that they never showed up for class that week. Whew. Ten minutes each, and as emotionally draining as grading 100 exams.

I feel Kristine’s pain. And, I think this raises the larger question of what the problem is that keeps these students from understanding that “course requirements” are things that are required for them to do.

Honor among journalism students.

Uncle Fishy and RMD pointed me to this story in the New York Times about a last-minute extra assignment (due today) for students enrolled in “Critical Issues in Journalism” at the Columbia University Graduate School of Journalism. Not an extra credit assignment, mind you — an extra assignment they all get to do just to pass the course, on account of the fact that the 200+ students enrolled in the class apparently had some trouble handling the exam without cheating:

Graduate school with kids: views from around the blogosphere.

It started when someone asked Dr. B. for advice about starting a Ph.D. program with three kids in tow. Since then, the question has been bouncing around the academic blogosphere, with posts you should read at Academom and Geeky Mom. Although this is absolutely the worst time in the semester for me to fire on all cyliders with this one, regular readers know that I’ve shared my own experiences in this area, so I can’t stay completely out of it.
A brief recap of the current conversation:

What’s the best way to excite kids about science (or at least not convince them it’s boring or impossible)?

On the heels of my post wondering where the science is in elementary school, I’m interested in your sense of how things stand now and what, if anything, you think we should do about the situation. Draw on your experience as a former (or current) student, a parent, an educator (including educating future teachers), a working scientist, or whatever.
The possibilities that have been raised so far seem to be:

A finding in need of an explanation

On the way home, I heard a story on NPR about a study done at UC Berkeley about the “performance gap” between black kids and white kids in the public schools. I can’t say much about the details of the report — it comes out tomorrow — but one of the people interviewed for the story, Ross Wiener of The Education Trust, noted a finding in this general area of research that screams out for an explanation.
The finding: while white students tend to lose ground during summer vacation (at least with respect to the sorts of performance easily measured with standardized tests and similar assessment methods, one assumes), black kids actually gain ground over the summer. (The text in the webpage for the NPR story says “minority kids lose less ground when they are away from school”, but listen to the sound file linked at the top of that page — Wiener really does say they gain ground.)
So, what could explain this unequal benefit from summer vacation? (For bonus points, how would you test the potential explanations?) And, is this a finding that will play any role at all in the decisions of districts considering eliminating summer vacation in favor of year-round instruction?
