There is a bill in the Wisconsin state legislature that would ban the teaching of creationism or intelligent design in public school science classrooms there. I have a brief analysis available at Dispatches from the Culture Wars.
Update: I’ve also got the full text of the bill, which reads as follows:
SECTION 1. 118.018 of the statutes is created to read:
118.018 Science instruction. The school board shall ensure that any material presented as science within the school curriculum complies with all of the following:
(1) The material is testable as a scientific hypothesis and describes only natural processes.
(2) The material is consistent with any description or definition of science adopted by the National Academy of Sciences.
