AUSTIN—A proposal for curriculum standards for science courses in Texas would remove language requiring students be taught the “strengths and weaknesses” of all scientific theories, wording which some say has been used to undermine the theory of evolution.

Proposals released Tuesday from review committees of teachers and academics would also put up roadblocks for teachers who want to discuss creationism or “intelligent design” in biology classes when covering the subject of evolution.

The biology review committee proposed language that states supernatural and religious-based concepts such as creationism have no place in science classes.

The standards are subject to approval by the state Board of Education, where a majority of members have said they are in favor of retaining the current mandate to cover both strengths and weaknesses of major scientific theories, notably evolution.

The issue comes before the board early next year. A close vote is expected. Standards adopted by the board will remain in place for the next decade.

The recommendations would drop the strengths-and-weaknesses rule for all science courses except astronomy and chemistry.

Groups backing science teachers lauded the proposed changes, but a conservative foundation said such a change would amount to censorship of teachers.

“These common-sense standards respect the right of families to pass on their own religious beliefs to their children while ensuring that public schools give students a sound science education that prepares them to succeed in college and the jobs of the future,” said Kathy Miller, president of the Texas Freedom Network.

Miller said the “strengths and weaknesses” requirement has been seized on by creationists to promote unscientific attacks on evidence supporting evolution.

Jonathan Saenz of the conservative Free Market Foundation said: “This type of pure censorship in shutting down a debate is the exact opposite of what true science is supposed to be. We strongly disagree with their recommendation.”

State Board of Education Chairman Don McLeroy, R-College Station, said Tuesday he will oppose the recommendation.
