Concept mapping, a technique based on David Ausubel's theory of meaningful learning, involves the organization of concepts into an hierarchical arrangement. Suggestions for incorporating this learning strategy into the biology classroom are presented and discussed. Steps in concept mapping include: (1) identifying important concepts in the study materials; (2) ranking concepts from the most general to most specific; and (3) arranging concepts on a piece of paper and defining connections between related concepts. A concept map for animals is developed from a textbook paragraph. Three student-designed maps (dealing with photosynthesis, cells, and organic compounds) and a form for quick scoring are included in an appendix. Also included are forms for assessing student-developed concept maps and a list of definitions for the word "concept." (DH)
