The instructional message: A theoretical perspective

This article presents a theoretical model for message design proved capable of improving the quality of instruction while increasing cost effectiveness. Integrating classical rhetoric, information theory, contemporary media criticism, social psychology, and the psychology of human information processing, the model directs the designer to design a block of time that optimizes the information load and message complexity within the constraints of the receiver’s abilities and experience, the requirements of the source, and the capabilities and limitations of the medium.
