After a detailed history and definition of Computer-Assisted Instruction (which identifies drill and practice, tutorial, and problem-solving activities as comprising CAI), the development and implementation of a college level computer based multimedia physics course is described as an example of tutorial activities in CAI for those interested in applying CAI to adult education. Special emphasis is placed on the base line student performance information, multimedia materials, staff differentiation, field tests, a systems approach, and cost effectiveness plans which were used in devising this program. An overview of computer hardware and software problems, such as cost (especially with reference to the advantages of centralized and decentralized systems), type of terminal device (such as the cathode-ray tube), and computer control of multimedia instructional devices is presented next, along with a brief indication of the problems involved in dealing with computer manufacturers and in training employees. Finally, computer applications which are being investigated at Florida State University are reviewed with reference to their implications for adult education: drill and practice, problem solving, computer-managed instruction, and computerized testing and educational guidance.
