The State Board of Education moved a step closer to dropping a 20-year-old science curriculum requirement that critics say is used to undermine the theory of evolution.
After two days of heated debate, the board made a key vote Friday in favor of dropping a mandate that teachers address both "strengths and weaknesses" of scientific theory.
A panel of science teachers had recommended that the language be dropped, suggesting instead that students be required to analyze and evaluate scientific explanations.
The new standards the board ultimately approves — a final vote on the curriculum proposal is not expected until March — will be in place for the next decade. They also will dictate how publishers handle the topic of evolution in textbooks.
Critics of the "weaknesses" language argue that watering down the teaching standards of origin of man is an attempt to promote creationism in public schools.
Federal courts have ruled against forcing the teaching of creationism and intelligent design.
Critics of the proposal to drop the mandate blame "left-wing ideology" for trying to stifle free speech.
A narrower requirement, adopted in an unexpected amendment Thursday, would require high school biology students to address the "sufficiency or insufficiency" of common ancestry to explain certain aspects of evolutionary theory.
