Abstract : This report describes the first year's work in a two year study of optimal structures for multimedia instruction. The project has two phases. The first phase elicits experienced instructors' explanations of a demonstration device, in order to obtain for analysis a significant range of the possible discourse structures that occur in instruction. The outcome of this phase is a set of variables, and a set of hypotheses about relationships among them that lead to effective instruction. The second phase will test these hypotheses on groups of students. The aim of this project is to provide experimentally validated guidelines both for the design of computer-based instruction generation systems, and for human instruction in a multimedia setting. Potential applications for this research include multimedia output capability (e.g., graphics output plus audio, using speech technology) for automatic instructional systems and for onboard fault diagnosis systems, as well as the improvement of traditional classroom instruction. Four major results have been achieved so far: a framework for discussing optimal discourse structures and/or visual presentations in multimedia instruction, based upon the notion of a mapping between semiotic systems; the discovery that the command and control speech act chain is used in 'hands-on' instruction (our structure theory of the discourse type is given; a rich set of experimental hypotheses; a demonstration of the viability of a methodology combining linguistic analysis with experimental research.
