In spite of considerable research on various aspects of pictures and their instructional uses, a clear conception of the instructional potential of pictures is missing. As a result, practitioners who deal directly with the instructional process are limited in their ability to use pictures most effectively and efficiently. The approach to picture research described here attempts to make research more relevant by suggesting the need to pay greater attention to the instructional role or function served by pictures. Potential functions must be described in terms of their contribution to instructional processes and procedures. Functions should also be applicable to a wide variety of objectives, strategies, and procedures. The relevance of this approach to both basic and applied pictorial research is also discussed.
