I haven't noticed a lot of people advocating teacher's right to teach anything they want. The question is whether science curriculum will be developed by people trained in science or by politicians.
But if "critical thinking" become required, it will be applied to things that are currently given light treatment, such as the age of the earth. I would love to see students learn the history of geology.
Responding to teacher's rights to teach anything they want, isn't this along the lines of havin a right to "choose" what teachers teach -- unless touchy or biased teaching is eliminated?
Not to be paranoid, but, when do people have the right over the family? Sounds like another "Left" talking point. Maybe my school should implement classes on "Liberalism", because said hypothetical professors think it is the right thing to do.
