Science education has become a focal point in recent years for discussion and speculation. Numerous reports indicate that science instruction is not producing high quality education. This document notes many of the changes in science education by citing historical trends in the field since 1940. It then goes on to describe a cooperative unified science program (for grades K-8 in Springfield, Ohio) known as the Modular Approach to Teaching Science (MATS). It outlines the evolution of the MATS program, including: (1) the appointment of a science coordinator; (2) the development of the experientially based unified science curriculum; and (3) the involvement of various contributors to the program, such as the city school system, science specialists, outside consultants, and federal funding. Evaluative comments about the program are also provided. (TW)
