History curriculum in Texas remembers the Alamo but could soon forget Hillary Clinton and Helen Keller.

As part of an effort to "streamline" the social studies curriculum in public schools, the State Board of Education voted Friday to adjust what students in every grade are required to learn in the classroom. Among the changes, board members approved the removal of several historical figures, including Clinton and Keller, from the curriculum.

The board also voted to keep in the curriculum a reference to the "heroism" of the defenders of the Alamo, which had been recommended for elimination, as well as Moses' influence on the writing of the nation's founding documents, multiple references to "Judeo-Christian" values and a requirement that students explain how the "Arab rejection of the State of Israel has led to ongoing conflict" in the Middle East.
