Here is the operative provision of a new Tennessee law:
SECTION 1. Tennessee Code Annotated, Title 49, Chapter 6, Part 10, is amended by adding the following as a new, appropriately designated section:
(a) The state board of education, public elementary and secondary school governing authorities, directors of schools, school system administrators, and public elementary and secondary school principals and administrators shall endeavor to create an environment within public elementary and secondary schools that encourages students to explore scientific questions, learn about scientific evidence, develop critical thinking skills, and respond appropriately and respectfully to differences of opinion about scientific subjects required to be taught under the curriculum framework developed by the state board of education.
(b) The state board of education, public elementary and secondary school governing authorities, directors of schools, school system administrators, and public elementary and secondary school principals and administrators shall endeavor to assist teachers to find effective ways to present the science curriculum taught under the curriculum framework developed by the state board of education as it addresses scientific subjects that may cause debate and disputation.
(c) Neither the state board of education, nor any public elementary or secondary school governing authority, director of schools, school system administrators, or any public elementary or secondary school principal or administrators shall prohibit any teacher in a public school system of this state from helping students understand, analyze, critique, and review in an objective manner the scientific strengths and scientific weaknesses of existing scientific theories covered in the course being taught within the curriculum framework developed by the state board of education.
(d) This section only protects the teaching of scientific information, and shall not be construed to promote any religious or non-religious doctrine, promote discrimination for or against a particular set of religious beliefs or non-beliefs, or promote discrimination for or against religion or non-religion.
The law mandates nothing, including the teaching of "creationism." What it does is protect teachers who want to inculcate critical-thinking skills in their students. Only a paranoid schizophrenic could object to it.
