Learners with little or no prior topic knowledge often receive the greatest benefit from instructional graphics because visuals help establish an initial mental framework for unfamiliar information. Experienced learners already possess schemas that help them organize concepts, recognize relationships, and interpret terminology. Novices do not have those existing structures.
Appropriate graphics can show processes, relationships, hierarchies, components, sequences, or physical structures much more efficiently than text alone. For example, a labeled diagram can give a novice learner a conceptual overview before detailed technical information is introduced.
However, graphics should serve an instructional purpose. Decorative illustrations that do not reinforce the learning objective can increase extraneous cognitive processing rather than improve understanding. Effective instructional design therefore uses relevant visuals that directly support comprehension.
Learners with intermediate or advanced experience can certainly benefit from diagrams and visualizations, particularly when information is complex, but their existing domain knowledge reduces their dependence on visual scaffolding. Novices generally require greater support in constructing an initial schema, making graphics particularly valuable for learners without previous topic background.
