Focusing on interactive, computer-based systems and external, long-distance instruction transmitted from one or more satellite earth stations, this paper begins by citing the need to experiment with and develop new delivery systems that will increase productivity in both teaching and learning. The use of satellite technology in Utah and Texas is discussed, as well as Washington State's program, "Satellite Telecommunications Educational Programming" (STEP). It is noted that computer-assisted instruction, computer-managed instruction, and other uses of computers in the classroom: (1) are not uniformly implemented as instructional innovations; (2) vary in effectiveness as teaching/learning tools; (3) vary in cost effectiveness; (4) are not always accessible to all groups of students; and (5) require systematic, sophisticated, and long-term inservice training of teachers, as well as a reworking of the scope and sequence of school curricula, in order to reach their potential. The relationship between educational technology and state educational agencies is discussed, particularly in terms of access to and quality of education; the extent to which the state regulates school governance; teacher certification; school accreditation; and the state-operated infrastructure that supports public education.
