The next skirmish in the long-running dispute about the teaching of evolution in Texas public schools is set for Wednesday.

That’s when scores of people, including six appointed curriculum reviewers, are expected to testify before the State Board of Education on a proposal for the next decade’s science curricula.

Today is the deadline to sign up to testify.

Scientists, educators and advocacy groups say creationists are trying to water down science education by calling for students to study the "strengths and weaknesses" of scientific theories such as evolution.

Educators removed the "weaknesses" phrase in the first draft of the science curriculum. After a public hearing in November that attracted more than 200 speakers, the phrase was put back into the second draft with the word weaknesses changed to limitations.

The third and final draft says students should be able to "analyze and evaluate" scientific explanations.
