Visual learning is a strategy for visually representing the structure of information and for representing the ways in which concepts are related. Based on the work of Ausubel, these hierarchical maps facilitate student learning of unfamiliar information in the K-12 classroom. This paper presents the research base for this Type II computer tool, as well as the alignment of the National Educational Technology Standards for Students (NETS*S) and the National Educational Technology Standards for Teachers (NETS*T). In addition, basic information is provided regarding use of visual tools as diagrams and outlines, along with multiple K-12 lesson ideas, adaptations for special populations, software options, and useful Web links.
