Except that Penny was far from the first state to attempt to do this, if one accepts that "Intelligent Design" is just another name for "Creationism." Several states now do have "anti-evolution" dictates in their "standard curricula."
Kansas attempted to do it, I believe in 1999, requiring the teaching of "Creationism as an alternate theory" or some such along that line. Elections and a new school board eliminated it then, and hopefully the same will happen again - but one never knows.
