Curriculum Frameworks for Mathematics and Science is the first in a series of monographs that is being produced by the Third International Mathematics and Science Study (TIMSS). TIMSS is an important international comparative study co-ordinated from the University of British Columbia. During the coming decade, TIMSS will examine the teaching and learning of science and mathematics in fifty countries. Curriculum Frameworks for Mathematics and Science describes the frameworks that will be used to examine the mathematics and science curricula, and includes the frameworks themselves in a series of appendices. The monograph also includes information on how the frameworks and curriculum analysis fit into the study as a whole.
