Re-aiming the canon.

Abstract Although it is unlikely that the national goals for educational reform--such as that, by the year 2000, U.S. students will be first in the world in science and mathematics achievement--can be achieved, a vigorous effort must be made to reach those goals as rapidly as possible. Reform will come not from a massive expansion of what we now do but from a basic shift in the manner in which we educate students in grades K-16 in the sciences and mathematics. Important elements in that basic shift must include an increase in teaching of science, mathematics, and technology (SMT), to about 20%-25% of the curriculum; SMT must include rich hands-on experiences, with an emphasis on concepts and understanding, rather than on facts and memorization, and on how science as a way of knowing differs from other ways of knowing; SMT must consider human problems; and SMT must deal with the basic problem facing humanity--how we must adjust our behavior so as not to exceed, on a worldwide basis, the carrying capacity of the environment.
