Use of computers for individualized instruction will bring about some new roles for what we now call teachers. In turn, these new roles will have many implications for colleges of education which must prepare teachers for these roles. In addition to master teachers, instructional managers, operations technicians, librarians, and proctors, a key role will be that of the instructional designer, who will write materials to store in computers or other self-instructional systems of the resource center. The model of instructional design used at the University of Texas Computer Assisted Instruction Laboratory includes five steps: outlining needs, goals, and a justification; developing the design architecture and rationale; writing an author's draft; producing a computer program; and evaluating the course. This method is exemplified by a design for teaching written Arabic and is considered a metaphorical representation of systems analysis. Cross-fertilization of disciplines (computer science and educational research) should provide advances in course content, course organization, and instructional methods. (JK)
