Attempting to define the optimal use of educational resources for large numbers of students, a research group at the University of Texas at Austin has adopted a system approach to curriculum development consisting of the following components: content, teacher, student, machine, and media. The first procedural step in the system is to define the objectives and tasks of the course in terms of related sets of behavioral objectives. Then, using information about teaching style, learning style, and available resources, a complete multimedia course can be designed that is tailored to the individual needs of the student. In one chemistry course, the technique was used to generate remedial modules to assist the student having difficulties with exam questions. Results indicate that computer based techniques relieve the burden on the instructor, and they have a positive effect on student achievement and attitudes. The appendixes include the flow diagram for the system design, a list of the tutorial modules used in the chemistry course, and cost data. (EMH)
