In a decision that will ultimately affect what tens of millions of U.S. students will learn, the Texas State Board of Education has endorsed new state standards for teaching history and social studies that reflect a conservative point of view, according to news reports out of Austin.

Reflecting a partisan political split, the Republican-dominated board voted, 10-5, to adopt the new 10-year curriculum for 4.7 million Texas students, one of the biggest and most influential markets for textbook publishers. Final approval is set for May.
