The Physical Science Study Committee (PSSC) was formed in 1956 to develop a new physics curriculum for high schools. The project was initiated by Jerrold Zacharias, James Killian, and Francis Friedman of the Massachusetts Institute of Technology; they formed the steering committee with I.I. Rabi, Edwin D. Land, Nathaniel H. Frank, Martin Deutsch, and others. With a grant from the National Science Foundation a preliminary edition of PSSC Physics (1958) was completed. The PSSC materials included a Laboratory Guide and a Science Study Series, which provided supplemental reading to the course. The project included summer in-service institutes to train teachers in the use of the new curriculum. In December 1958, Education Services Incorporated (ESI) was formed to take over the administration of PSSC, including overseeing publication of the first commercial edition of PSSC Physics (1960) by the D.C. Heath Company. ESI then undertook other projects to improve educational programs and in 1967 merged with the Institute for Educational Innovation (IEI), which had been established under Title IV of the 1965 Elementary and Secondary Education Act, to form the Education Development Center (EDC). EDC was involved in many large-scale projects aimed at educational reform.
