This chapter on electronic concept mapping introduces a specific example of a learning technology that has potential for serving and promoting an emerging set of identified literacies in today’s youth. The chapter begins with a discussion of the nature of the modern student and the literacies that are most likely to serve them well as they integrate into an increasingly technological information-based society. A discussion of the historical development of the concept map and its defining characteristics will follow. The range of applications of concept maps in K-12 classrooms will then be discussed with additional comments regarding teacher development both in preservice and inservice settings. The chapter will close with a discussion of the particular literacies served by electronic concept mapping.
