ABSTRACT
The article discusses research which the authors conducted about students' ideas regarding natural selection using a constructivist model of instruction to develop an evolutionary biology curriculum. According to the article, constructivist philosophy involves building new ideas into those already held by students. The authors surveyed high school freshmen students in general science and high school senior biology students about their knowledge of natural selection and scientific investigation. The concepts of population variation, mutation and the genetic basis for diversity, and selective environmental pressure. The survey results implied that students are ready to accept natural selection as the scientific theory to best explain diversity.
