To be successful in today's educational climate schools must select and implement rigorous and relevant science and mathematics curricula. Since the publication of a Nation at Risk (1983), schools across the U.S. have sought to meet a growing demand from business and government to increase the level of academic rigor in disciplines, such as mathematics and science for all students. Enhancing the quality of mathematics and science curricula remains as a priority for our nation's educational institutions. In fact, accountability legislation, such as No Child Left Behind (2001) creates additional pressure for educators to take a serious look at curricula, especially in the areas of mathematics and science, selected to support local, district, state, and national learning priorities. Creating and implementing both rigorous and relevant mathematics and science curricula is also necessary to support U. S. business and industry in meeting employment and training needs for science, technology, engineering, and mathematics (STEM) careers (NSF 2004).
