A project being conducted by the MITRE Corporation and Brigham Young University (BYU) is developing hardware, software, and courseware for the TICCIT (Time Shared, Interactive, Computer Controlled Information Television) computer-assisted instructional system. Four instructional teams at BYU, each having an instructional psychologist, subject matter experts, an instructional design technician, an evaluative technician and packaging specialists, are developing courses in remedial algebra, elementary functions, remedial English, and freshman English for junior colleges. The system uses a color television to display digitally generated characters and graphics and also employs audio and video tapes and alphanumeric entries from a typewriter. Major courseware features include three levels of student-machine communication, a modular approach to courseware structure designed in accordance with a taxonomy of instructional variables, and learner-controlled interfaces between the student and the system. The courseware seeks to present the required content to students at a low cost in such a way that they develop content mastery in an effective manner and also acquire improved learning strategies, a positive outlook to learning and greater responsibility for their own development. The courseware will be field-tested at two junior colleges in 1974. (PB)
