The Ohio school board voted Tuesday to eliminate a passage in the state's science standards that critics said opened the door to the teaching of intelligent design.
The Ohio Board of Education decided 11-4 to delete material encouraging students to seek evidence for and against evolution.
The 2002 science standards say students should be able to "describe how scientists continue to investigate and critically analyze aspects of evolutionary theory." The standards include a disclaimer that they do not require the teaching of intelligent design.
The board vote represents the latest setback for the intelligent design movement, which holds that life is so complex it must have been created by a higher authority.
In December, a federal judge barred the school system in Dover, Pa., from teaching intelligent design alongside evolution in high school biology classes. The judge said that intelligent design is religion masquerading as science, and that teaching it alongside evolution violates the separation of church and state.
