This document discusses concept maps, which are visual representations of relationships between concepts in a subject area. Concept maps use labeled nodes for concepts and labeled directional lines to show relationships between concepts. When building a concept map, students choose a topic, brainstorm related concepts, arrange concepts hierarchically from general to specific, and connect concepts with labeled lines to form propositions. The document provides tips for using concept maps, such as connecting them to course readings, and discusses assignments where students created concept maps over the course of a semester.
