Educational technology: Media for inquiry, communication, construction, and expression

Abstract

We describe a new way of classifying uses of educational technologies, based on a four-part division suggested years ago by John Dewey: inquiry, communication, construction, and expression. This taxonomy is compared to previous taxonomies of educational technologies, and is found to cover a wider range of uses, including many of the cutting-edge uses of educational technologies. We have tested the utility of this taxonomy by using it to classify a set of "advanced applications" of educational technologies supported by the National Science Foundation, and we use the taxonomy to point to new potential uses of technologies to support learning.
