I suppose it's the 16% of "science" teachers who self-identify as creationists (I guess it's good that they're considerably more knowledgeable than the general public).

To quote from the study:
"These findings strongly suggest that victory in the courts is not enough for the scientific community to ensure that evolution is included in high school science courses. Nor is success in persuading states to adopt rigorous content standards consistent with recommendations of the National Academy of Sciences and other scientific organizations. Scientists concerned about the quality of evolution instruction might have a bigger impact in the classroom by focusing on the certification standards for high school biology teachers. Our study suggests that requiring all teachers to complete a course in evolutionary biology would have a substantial impact on the emphasis on evolution and its centrality in high school biology courses. In the long run, the impact of such a change could have a more far reaching effect than the victories in courts and in state governments."
I wonder how many of that 16% are "well qualified" and credentialed teachers and how many are just, well ... hacks, who were assigned to teach a science class, but who had no more preparation in biology, science or evolution than some of my opposition posters on the board here. It would be interesting to see a breakdown of the data comparing "well qualified" and "unqualified" science teachers.
