MADISON, Wis. -- A move by the Texas State Board of Education could have local implications in Wisconsin.

A preliminary vote in favor of a new social studies curriculum would require revisions in textbooks marketed nationwide, including those used in Madison schools.

Susan Hamblin is part of a committee that reviews social studies textbooks for the Madison Metropolitan School District and said they've tried to choose textbooks that fit the students.

"So, this is the textbook we wrote for the history of Madison. You can see that it is appropriate for third-grade kids. It's reader friendly, bright and colorful, said Hamblin.

She pointed out that that Madison schools use certain criteria to evaluate textbooks.

"Some of the things that we look for of course, is it research based? Does it provide evidence, primary sources, examples of that in the textbook," Hamblin said.

However, the Texas measure has some folks worried history might be rewritten.

"These are not historians. These are basically political figures and they have enormous power because Texas is a major textbook adoption state," said Paul Boyer, a history textbook author.

According to the Texas vote, kindergarten through 12th-grade curriculum wouldn't add any important Hispanic figures to textbooks, and would refer to the U.S. government as a "Constitutional Republic" instead of being "Democratic."

"It is disturbing and disappointing to see this really fundamental lack of trust and suspicion; that somehow when historians set out to write textbooks they have a political agenda that they're seeking to impose," said Boyer.

If the new standards are approved in Texas, textbooks -- new and old -- will be revised.

In Madison, the district's evaluation committee said it is confident that its process recommends only the best.

"It is a very laborious process, but one that we feel very comfortable that we have indeed covered and met the standards," said Hamblin.

The Texas board of education voted 10 to 5 in favor of adopting the new curriculum. But the final vote will not take place until May.

One expert said that publishers could put out a special edition to meet the Texas requirements, but that means Texas students would learn a slightly different history from their peers in other states.
