Static, animated, and interactive visualizations are frequently used in electronic learning environments. In this article, we provide a brief review of research on visuospatial cognition relevant to designing e-learning tools that use these displays. In the first section, we discuss the possible cognitive benefits of visualizations consider used in e-learning environments. In the second section consider cognitive constraints on the use of visualizations and design guidelines intended to reduce impact of these cognitive constraints. Finally, we consider how individual differences interact with learning from visualizations and how the use of visualizations might be altered for students of different abilities.
