As we experiment with uses of technology, we must resist a simplistic view of the venture. Technologies are more than means to ends. They change our goals, for they change our very natures as organisms. It is believed that educators cannot refrain from extensive technological innovation. In doing so, however, they must sensitize themselves to the fact that the changes will ramify in profound and unpredicted ways. R. A. Meisler herein presents an inventory of promising and as yet unassimilated educational technologies, and discusses some of the general issues and puzzles that appear to be important to a consideration of technology in education. The inventory: audiotape, overhead transparencies, slides, motion pictures, intermedia configurations, and multimedia configurations. (GO)
