The development of motion visual instructional messages should proceed according to systems principles. This would permit the creation of more effective visual messages, allow educators to use more effectively the various media as communication tools, and assist in the refinement of the instructional development process. Like any system, a system for the development of motion visual instructional messages contains inputs, processes, and outputs. Inputs include needs and goals, a mastery model describing the student's role in the setting where he will be expected to use the capabilities he learns from instruction, constraints, and evaluation data. Essential processes which must be found in the system are: content analysis, presentation analysis, scripting, production, and implementation design. The outputs of such a system will be instructional messages which meet the requirements of: 1) integrity (completeness); 2) fidelity (clarity and precision); 3) validity; and 4) reliability. (PB)
