A computer-managed instructional (CMI) system is being developed for use in investigating a CMI environment for Air Force technical training using the PDP 11/20 minicomputer. Software and hardware interfaces are now available for 24k core memory with an additional 128k random access disc storage. Hardware interfaces are complete for the student key-readers, an interactive graphic terminal, a test form reader and a computer-controlled slide projector. The CMI system also uses the manufacturer's hardware such as the cathode ray tube terminal, card printer and line printer. Key reader devices, capable of reading data from a coded key, identify the user and his location to the system and monitor the use of instructional materials and media not controlled by the computer. Computer software to operate the hardware is ready, and a series of short lessons is available which demonstrate how an instructional course can be managed using a sample adaptive model with pre-tests, lesson options based on student characteristics, course tests and feedback for students and instructors.
