Concept maps are a tool developed at Cornell University. designed for use as a metacognitive strategy. or a general strategy. that helps the student "learn how to learn." The goal of this paper is to illustrate how concept mapping can be used to integrate multidisciplinary subject maUer. assist the teacher in understanding the knowledge base of the student. reveal misconceptions or missing conceptual links. help resolve communications problems between the student and the professor. and encourage reflective thinking by all participants in the learning process. Three specific teaching situations are presented: 1) preparation of class materials. 2) communication with students in the classroom or the office. and 3) training of a teaching assistant. Examples of actual concept maps drawn by the author and her students are included.
