This project was based upon the need to develop a science curriculum program specifically designed for elementary education students. A program of classroom and field operations in life sciences, designed to provide minimum preparation for a prospective teacher on a self-contained classroom was developed. It portrayed life science as a "doing" subject. Evaluation of the course was based on the degree of improvement in knowledge of basic biology as measured, pre and post, by the Nelson Biology Test after a nine-week summer session. Students in the "Life Science" program made significantly larger gains than did those in the control group. (EB)
