This report considers one school's approach to science education, examining in particular the development of a two-semester required unified science course. Designed to be useful to all students and applicable to all areas of science, the course is characterized by a high degree of teacher teamwork, as in developing instructional materials. Science teachers organized instructional units around key concepts, process skills, natural phenomena, and science-related problems and identified target objectives for each unit. The teacher-developed course is inexpensive and flexible, easily accommodating timely themes. A full description of Rex Putnam High School's science offerings is given, including course descriptions from the school catalog. Pretest and posttest assessments indicate statistically significant increases in process skills measured, with no significant decrease in skill competencies throughout students' remaining high school years, whether or not they elect additional science courses. Teachers attribute the popularity of elective science courses to effective preparation in the required sequence. The process of teacher development of local programs is cited as the key to successful implementation, and replication of the unified science curriculum in other schools is discussed. Appendixes include a list of key concepts and skills and some considerations for local science curriculum development. (MJL)
