The Lt. makes an important point I’ve been meaning to address in his response to my suggestion that much of biology can be taught without the theory of evolution (emphasis added):
You may not need evolution to teach biology, but you pretty much do need it to teach biology well. I don’t know if you saw the new AAAS report on revamping the undergrad biology curriculum. The focus is undergrad and not high school. But they identified core concepts and the very first one was evolution. I guess it all depends on the class and what you’re hoping to accomplish.
In grad school I took a class on “Science Education for Scientists and Engineers.” Perhaps the most interesting discussions we had centered on the justifications for public science literacy. That is, why do we teach everyone science? Surely society’s need for scientists and engineers can be satisfied by training a small elite. But we clearly care about more than just that. The endless exhortations for more science education reflect, I believe, the belief that science must mean something for everyone.
And here is where it gets a little tricky. From my light reading in the field, there really is no expert consensus on why or how we foster a general public understanding of science. Scholars generally agree that science education should leave people with some content knowledge, some understanding of scientific methods, and some sort of appreciation for and engagement with science. But specifically what content, and how much process, and how to best cultivate appreciation is a mystery.
From my standpoint, if we care even a little about the last goal (and I believe we should care a lot), then we must tread carefully around thorny topics like evolution. It doesn’t mean that evolution is not important (it surely is), or that the theory should be avoided (it shouldn’t). But a strident, narrow defense of evolution may undermine scientific literacy writ-large. Do we really want to tell people that they are unwelcome in physics and chemistry if they don’t believe in evolution? And do we have to do it so angrily?
In evolution and in politics, I wish we could all just try a little tenderness.
