Developments in electronic technology that have improved and linked together telecommunication and computers are discussed, as well as their use in instruction, implications of this use, and associated issues. The first section briefly describes the following developments: microcomputers and microprocessors, bubble memory, lasers, holography, optic fibers, satellite-to-rooftop communications, videodiscs, charge-coupled devices and the application of electronic technology to communication. The potential of these developments for education is then explored by showing how telecommunications and computers can be used in instructional programs as a source of information, a source of dynamic interaction, or resources for managing instruction. The possible impact of electronic technology on educational aims and content is also discussed, as well as the question of when and where electronic technology will be used in education. A bibliography of 29 items is included. (Author/CHC)
