Far from the classroom, an intense but nearly invisible battle is being waged for the hearts and minds of Minnesota's schoolchildren.
The fight is over how history and other social studies topics will be taught, long a flashpoint for political strife in Minnesota.
At issue is the state Department of Education's proposed revision of social studies standards -- a massive overhaul two years in the making.
An administrative law judge will decide whether schools can teach the new standards beginning this fall.
Critics say the new standards favor an "America the Ugly" narrative of U.S. history. They say there is too much focus on slavery and oppression of American Indians and too little on "American exceptionalism," the nation's inherent greatness and God-given rights as laid out in the Declaration of Independence.
Meanwhile, social studies teachers see a conservative attempt to "indoctrinate students with ideological and religious values."
As was the case during the controversy surrounding the Profile of Learning standards in the 1990s, which launched the career of U.S. Rep. Michele Bachmann, Minnesota cares a lot about how history, economics, geography and civics are taught in K-12 classrooms.
"If we don't understand -- if our students and children don't understand -- the basic workings of our republic, it won't be there for very long," said Karen Effrem, president of Education Liberty Watch, which has led the charge against the new standards.
