Reviewing computer applications in reading and reading instruction, this article covers the following topics: the emergence of computer instruction from teaching with television, the variety of input and output devices, types of interaction between user and program, methods and approaches, degrees of generalization, scope and capacity of programs, and adaptability to and acceptance by various populations. Relevant literature is examined from the following perspectives: (1) understanding of the reading process through computers, (2) training of reading teachers through computers, (3) the use of computers in reading instruction--computer aided instruction, computer managed instruction, and the role of the programer. Some of the hardware and software mentioned include: CARIS (Computer Animated Reading Instruction), IBM 1500 (designed specifically for instructional purposes), HP2000F (computer), Commodore PET Computer, TRS-80 Voice Synthesizer, Sol-20 Computer, Lite I (Initial Reading and Job Orientation Program), and Lite II (Career Oriented Reading in Various Job Areas), Simuread Program, and PLATO. It is urged that computers be regarded as a valuable aid to teachers in providing quality education and researching reading behavior. Conclusions speculate on why computers are not utilized more fully in reading research and instruction given their abounding capabilities and exiting applications to the field. (Author/JD)
