AUSTIN, Texas — Parents, teachers and activists lined up Wednesday for the chance to help shape the way history — topics from the Roman Empire to Texas cosmetics queen Mary Kay Ash — will be taught to millions of Texas children for the next decade. The State Board of Education began taking testimony ahead of a tentative vote later this week on new social studies curriculum standards that will serve as the framework in Texas classrooms. Board members are still crafting amendments for consideration before the tentative vote, expected Thursday. The 15-member board won’t adopt final standards until March. The curriculum it chooses will be the guideposts for teaching history and social studies to some 4.8 million K-12 students for 10 years. The standards will be used to develop state tests and by textbook publishers who develop material for the nation based on Texas, one of the largest markets. In early testimony, the board was urged to include more influential Mexican Americans in the nation’s history and to further acknowledge Sikhism as a major world religion. Fifteen-year old Harsimran Singh, who attends Round Rock High School, said the lack of understanding about his religion is "dehumanizing” and implored the board to require more discussion of the religion that mandates he wear a turban. "I would like other people to know that I’m not Osama bin Laden,” Singh said. "I know a little bit about Christianity, I would like other people to know about my religion as well.” Shammi Gill of Houston presented a petition signed by hundreds, seeking more discussion of Sikhism. Much of the conversation turned to how much emphasis will be given to the beliefs of the nation’s founding fathers, with some lobbying to promote their Christianity. Others who promote the separation of church and state prepared for battle. "An education without some understanding of the profound role of religion in our nation’s history and its contributions to our nation’s success is an incomplete education and our courts have often said as much,” said Derek Davis, director of the Center for Religious Liberty at the University of Mary Hardin-Baylor. "What violates the Constitution is presenting material that either prefers Christianity over other faiths or depicts the United States as a Christian nation in some legal or constitutional sense.” More than 130 people signed up to testify Wednesday.
