Abstract
STS represents a significant reform effort in science/technology education in grades kindergarten through the undergraduate collegiate years. It focuses on use of constructivism as a way of learning and a broader view of science, and as a way of assessing learning for real understanding. Basic to STS is teaching and the assessment of learning in multiple domains, namely, concepts, processes, the application of both to new situations, the nature and history of science, creativity skills, and attitude. When education occurs in STS classrooms, students grow significantly in all domains and more so than in traditional classrooms.
