Abstract
The author reviews the research on the effectiveness of graphics in instruction and then proposes a framework for developing a theory that accounts for the syntax, semantics, and pragmatics of graphics. His goal is to lay the groundwork for developing prescriptive guidelines for the design of effective graphics in training documents. He stresses that further research needs to be done in order that a theory of learning from graphics can be developed in sufficient detail for design prescriptions to be provided and that prescriptive theory for graphic design is necessary
