Are our high schools teaching evolution?

Blogging on Peer-Reviewed Research

The Ecological Society of America has just published an article that surveys the state of science teaching in the US. Some of the results are somewhat reassuring — the majority of our college-bound high school students are at least getting exposed to evolution to some degree — but they’re also getting taught creationism to an unfortunate degree. Here’s the abstract to give you the gist of the story.

How frequently and in what manner are evolution, creationism, and intelligent design taught in public high
schools? Here, I analyze the answer to this question, as given by nearly 600 students from major public universities nationwide in a survey conducted during the spring of 2006. Although almost all recent public high-school graduate respondents reported receiving evolution instruction, only about three-quarters perceived that
evolution was taught as a “credible scientific theory”. Creationism and intelligent design were reportedly presented almost one-third and one-fifth of the time, respectively, though respondents recalled that both concepts
were presented as lacking scientific credibility much more often than not. The survey results are presented in
composite form and also disaggregated with respect to the strength of evolution-related state standards, red
state-blue state divisions, and the regional location of states within the country.

You can also hear the author discussing the methodology and results in a podcast, which I think is a wonderful idea. (Maybe every paper should be accompanied by a 15 minute podcast in which the author explains the work to a general audience…).

Here’s the good news/bad news data.

The good news: look at that, 92% are getting taught about evolution to varying degrees. I also think it’s good news that 26% say they’re getting “in depth” instruction, although, of course, this is self-reported by students who probably don’t know how much depth there is. At least this tells me that a solid majority of teachers are trying, and are not silenced by pressure from the public.

The bad news: 30% are getting taught about creationism, and 20% are learning about intelligent design. That’s a waste of time and resources, and it’s an indicator that the urgings of creationists for a false “fairness” might be having some effect.

Now, of course, maybe they’re learning about creationism in high school because the teacher is slamming it as bogus nonsense, as I do in my university classes. There’s a little good news there, too: over 70% of the time, evolution is taught as credible theory, but as for creationism…

Additionally, when intelligent design is taught, it is
perceived to be presented as a credible scientific theory at
a rate higher (34%) than that for creationism (18%).
This confirms one of the few narrow points of agreement
between intelligent design’s proponents and critics: intelligent design is intended to look more “like science” and
less “like religion” — and to these recent public high-school graduates, it does.

So we can say that the majority of the time creationism is taught, it is disparaged to some degree and is not taught as a credible scientific theory. That’s reassuring. Of course, we could take a glass-half-empty view and note that in those cases where ID is taught, it’s taught as a credible theory an appalling third of the time, and it’s also a successful strategy for boosting the reputation of creationism.

The situation isn’t quite as bad as I feared, although there is a significant minority that are getting taught creationism uncritically in the public schools. What I’m missing is a couple of things. This is information taken from a select population of college bound students, and those students are more likely to have had exposure to science, and are also more likely to be attentive. I’d like to know what impressions other students have of their science instruction.

This is also a collection of exactly that, student impressions. I’d like to see a complement to this study that surveys actual curricula and faculty attitudes. I know how tuned out students can be, so I can’t say that I entirely trust student reports.

John West caught quote-mining

It’s no surprise that a fellow of the Discovery Institute would distort his critics, but it’s still entertaining to see the quotes lined up with the manglings. If you’re a real masochist, you can catch West droning out the same old lies on Book TV. I’m not; I heard him speak on this subject once before, and it was infuriating in the depths of his bad history and even worse science.

An historical meme

Wilkins tagged me. It’s all his fault.

This is supposed to be a historical meme…why bother me with this? I think it’s because philosophers have a professional obligation to annoy people with weird questions, and Wilkins takes personal pleasure in poking me now and then, the brute. Here’s what I’m supposed to do.

  1. Link to the person who tagged you.
  2. List 7 random/weird things about your favorite historical figure.
  3. Tag seven more people at the end of your blog and link to theirs.
  4. Let the person know they have been tagged by leaving a note on their blog.

Favorite historical figure?? I don’t suppose I can name the progenote or urbilaterian, but because this was started by some historian somewhere, I have to restrict myself to some boring recent human being; and like Wilkins, I should avoid the obvious choices, although in his case Frederick II Hohenstaufen was a cool dude.

I guess I’ll name another cool dude…

Oscars?

Does anybody care about them anymore? I didn’t watch it at all, and I also missed most of the nominated movies this year. We had the winner, No Country for Old Men, playing in town a few weeks ago, unfortunately coinciding with an exceptionally heavy work week for me, and I couldn’t find time to see. There Will Be Blood is playing at the Morris Theatre this week, and I may have to squeeze in a few hours to check it out…but not because Day-Lewis won an award.

Isn’t that what it’s about, anyway? If we’re going to take off 3 hours or more for some entertainment, it makes more sense to go see the movie than to watch a tedious show about the movies.

Another suggestion

In response to your efforts to turn Pharyngula’s domination of the virtual scienceblog world into a real world conquest, John Wilkins has suggested another strategy for organizing meetups: Facebook. There is a Scienceblogs Facebook group, which could be a useful tool for finding people in your region. There is also a Pharyngula Facebook group and a PZ Myers for World President Facebook group (shouldn’t that be “PZ Myers for Galactic Overlord”?)

So there we go, another mechanism for finding each other.

Lawyers: here’s a profitable target

What organization rakes in the cash by exploiting the poor and making extravagant claims that never come true? What business is built entirely on mass marketing and dishonest advertising, and yet is never called into account for its failure? It isn’t the tobacco companies or the makers of penis enlargement drugs — it’s religion.

I have no idea whether this is a brilliant idea or just the daydream of an ambulance-chasing shyster, but someone is pursuing Earths Greatest Lawsuit — an effort to gather a swarm of plaintiffs to slam various religious organizations with numerous lawsuits.

It’s an interesting idea. I’m not a fan of the sue-them-into-compliance strategy for social issues myself (I want people to change their ideas, not bankrupt them and make them powerless), but I do like the idea of making religious organizations accountable for their real-world claims.

Besides, God is a ripe fruit ready for plucking — everyone knows the Devil has all the lawyers.

How Ricky Gervais lost his faith

Ricky Gervais has published his deconversion story — I feel a little inferior because he made up his mind about it very quickly, while it took me years to ease my way out of the nonsense.

I like his answer, though, especially the last paragraph below.

…within an hour, I was an atheist.

Wow. No God. If Mum had lied to me about God, had she also lied to me about Santa? yes, but who cares? The gifts kep coming. And so did the gifts of my newfound atheism. The gifts of truth, science, nature. The real beauty of this world. Not a world by design, but one by chance. I learned of evolution—a theory so simple and obvious that only England’s greatest genius could have come up with it. Evolution of plants, animals, and us—with imagination, free will, love and humor. I no longer needed a reason for my existence, just a reason to live. And imagination, free will, love, humor, fun, music, sports, beer, and pizza are all good enough reasons for living.

But living an honest life—for that you need the truth. That’s the other thing I learned that day, that the truth, however shocking or uncomfortable, in the end leads to liberation and dignity.

Cline at UMTC

Hey, Minneapolitans — Campus Atheists, Skeptics, and Humanists have two big events coming up soon. This week, it’s pizza and bowling on the UMTC campus. I’m probably not going to be able to make that one, but the week after, on 6 March, Austin Cline will be speaking on critical thinking and skepticism, and I may be able to get into town for that one. Let’s all go say hello to another godless blogger!

The genome is not a computer program

The author of All-Too-Common Dissent has found a bizarre creationist on the web; this fellow, Randy Stimpson, isn’t at all unusual, but he does represent well some common characteristics of creationists in general: arrogance, ignorance, and projection. He writes software, so he thinks we have to interpret the genome as a big program; he knows nothing about biology; and he thinks his expertise in an unrelated field means he knows better than biologists. And he freely admits it!

I am not a geneticist or a molecular biologist. In fact, I only know slightly more about DNA than the average college educated person. However, as a software developer I have a vague idea of how many bytes of code is needed to make complex software programs. And to think that something as complicated as a human being is encoded in only 3 billion base pairs of DNA is astounding.

Wow. I know nothing about engine repair, but if I strolled down to the local garage and tried to tell the mechanics that a car was just like a zebrafish, and you need to throw a few brine shrimp in the gas tank now and then, I don’t think I would be well-received. Creationists, however, feel no compunction about expressing comparable inanities.
