High School Biology Teachers in U.S. Reluctant to Endorse Evolution in Class, Study Finds
The majority of public high school biology teachers in the U.S. are not strong classroom advocates of evolutionary biology, despite 40 years of court cases that have ruled teaching creationism or intelligent design violates the Constitution, according to Penn State political scientists. A mandatory undergraduate course in evolutionary biology for prospective teachers, and frequent refresher courses for current teachers, may be part of the solution, they say.
"Considerable research suggests that supporters of evolution, scientific methods, and reason itself are losing battles in America's classrooms," write Michael Berkman and Eric Plutzer, professors of political science at Penn State, in the January 28 issue of Science.
The researchers examined data from the National Survey of High School Biology Teachers, a representative sample of 926 public high school biology instructors. They found only about 28 percent of those teachers consistently implement National Research Council recommendations calling for introduction of evidence that evolution occurred, and craft lesson plans with evolution as a unifying theme linking disparate topics in biology.
In contrast, Berkman and Plutzer found that about 13 percent of biology teachers "explicitly advocate creationism or intelligent design by spending at least one hour of class time presenting it in a positive light." Many of these teachers typically rejected the possibility that scientific methods can shed light on the origin of the species, and considered both evolution and creationism as belief systems that cannot be fully proven or discredited.'
