ethics within science teaching

Garrett's August 7 posting about the ethical dilemma of an activity that is likely to result in animals' deaths coincided with an interesting and unsolicited email I received. If you haven't read Garrett's blog about the controversial fish maintanance activity, then I think that you should. It would quite easy to brush-off concerns about fish deaths as being sissy or silly -- with all the harsh masculinity that underlies such a stance. But what an odd contradiction to claim that biology is the study of life and then require a lab that leads to death. Yes, I know those are complementary. And it is killing me (sorry!) that I haven't had a chance to begin reading Sex and Death: An Introduction to the Philosophy of Biology even though it is sitting on my shelf. But the point is that we must be sensitve to students' views even as those give us occasions for modeliing the best of what it means to be a caring human being.

The email came from a Research Associate from People for the Ethical Treatment of Animals. Yes: PETA! But here is an example where it seems possible to strike a reasonable balance. Julian Carr wrote:

Last summer, after the NSTA amended its position statement to acknowledge the viability of non-animal alternatives to dissection, I wrote to you with information about the availability and efficacy of non-animal learning methods in elementary and secondary science education. I hope that you found this information helpful and informative.

Following this nice introduction, Julian offered a website where science teachers can access "virtual" dissections for use in science classrooms. Here it is: http://peta.org/dissection. From what I can tell, none of these are free. But it seems like a reasonable alternative for those students who are troubled by dissecting actual animals. I anticipate some of these companies will be exhibitors at the NSTA Meeting in Philadelphia. And who knows: maybe your future employer would be willing to spring for the costs of some of these if you feel they are worthwhile.

science and belief

Those of us who devote ourselves to science literacy are challenged by the term "belief" — sometimes it fits and in other cases it causes fits. As an example of the latter, here is the position of someone who is an active campaigner for evolution in schools. Her National Center for Science Education is on the front lines battling creationists and "intelligent design" incursions in to public schools. I like that their logo is a rendition of Darwin's original notebook sketch of a "tree of life" -- just prettied up to look nice on a web page.

Below is a statement by Eugenie Scott (Exec. Director of NCSE) describing the need for careful language when talking about evolution. Her concern is based in potential misinterpretations of what it is that scientists do, especially within the context of evolution (from a Science New article, August 1, 2009 "Accept It…"):

You believe in God. You believe your sports team is going to win. But you don’t believe in cell division. You don’t believe in thermodynamics. Instead, you might say you “accept evolution.”

The point Dr. Scott is making is that when a scientist relies upon "belief" when talking about evolution, then the public may interpret that perspective as mere opinion. She points out that education is politicized. She feels responsible for educating the public about the facts of evolution. Within those efforts, she avoids controversy by refusing to invoke "belief" in reference to the work of scientists.

However, within discussion about the nature of science, we concede the human dimensions of the scientific enterprise: our fallibility due to pre-judgments, the significance of creativity ways of looking at problems, and the tentativeness with which we make scientific claims. In this vein, physics professor John Armstrong at Weber State University, offers this explanation of science:

The scientist believes that the universe is understandable and that the universe is knowable. And we don't know if that's true or not. And so when somebody talks about science-based reasoning or faith-based exploration — I mean, science is faith-based. Right? You believe the human mind can comprehend the universe.

So what is a science teacher to do? It seems this is another example where maintaining a careful balance is required. Perhaps it would be best to follow Eugenie Scott's advice when trying to represent the culture of science for students. But when we are safe to become philosophical, perhaps then we could concede that part of what makes science so compelling for the professional is the shared ideology or belief system that all our efforts will have a pay-off. Without any guarantee that it will in fact come to pass, we operate with the belief that the universe can make sense when examined with a scientific worldview. We just need to be careful who is listening when we make such confessions.
