This volume is composed of 11 source documents which report activities sponsored by the National Science Board Commission on Precollege Education in Mathematics, Science and Technology, deliberations of a subgroup of the National Science Foundation Engineering Advisory Committee, and a paper prepared for the Pfizer Corporation. The first four presentations address the teaching/learning of mathematics, science, and technology in grades K-12. Issues of appropriate content and process are discussed. Suggestions for changing some of the content of traditional elementary and secondary education are presented and arguments for the need for all students to study mathematics, science, and technology every year during their elementary/secondary education are made. Section five reports on the uses of technology as a tool in education rather than learning about technology. The last five sections report on: research and cognition and behavior relevant to education in mathematics, science, and technology; results of a 50-state survey of initiatives in science, mathematics, and computer education; magnet schools; an assessment of programs that facilitate increased access and achievement of females and minorities in K-12 mathematics and science education; a case study of Lyons Township (LaGrange, Illinois) high school computer literacy program; and business' role in precollegiate education.
