The study focused on three fields of science: biology, chemistry, and physics. The data were collected shortly after the introduction in many countries of reforms in science education. Thus, the study was concerned not only with achievement across the domain of science, but also with attitudes, methods of teaching, the development of practical skills, and an understanding of the nature of science. The data were collected in 1970–1971.
