In 1985, People for the American Way released its first review of biology textbooks that was inspired by the ongoing controversy over whether or not (and how) evolution should be taught in public school classrooms. The purpose of this review is to gauge how successful the response of educators and scientists have been at convincing publishers that teachers, parents, and state education leaders want biology textbooks that do not compromise science for sectarian ideology or confuse scientific process with religious conviction. In addition, this review is designed to assist textbook selection committees as they choose the next generation of biology texts for their schools. This publication contains the following: (1) findings from this review; (2) selection criteria concerning the treatment of evolution; (3) selection criteria concerning the treatment of the nature of science; and (4) individual reviews of nine biology textbooks published from 1987 to 1991 for use in secondary school classrooms.
