S. Pixy Ferris and Hilary Wilder discuss the changes that are occurring in teaching and learning in a world where teachers and students are increasingly products of two different learning cultures. Adopting the linguistic theory of Walter J. Ong, they see teachers as part of a print paradigm of learning whereas they propose that students are increasingly part of a secondary-oral paradigm of learning. The growth of the secondary-oral paradigm, they argue, has been fueled by the expansion of technologies that allow for the communal cohesion of oral-based cultures on the one hand while also allowing for the preservation and convenient transmission of knowledge that characterizes print-based cultures on the other hand. In this context, Ferris and Wilder argue that wikis provide one possible tool to help bridge the gap between teachers and students. They contend that wikis draw upon the best aspects of print and secondary orality by offering a medium in which information is neither fixed in format (as it was in the print age) nor limited to locale (as it was before the print age) but still changeable to meet the needs of the community, freely accessible to remote parties, and easily archived for future use. After addressing some of the debates that have characterized the legitimacy of wikis as learning resources, Ferris and Wilder illustrate and discuss potential uses for wikis in educational settings, and they offer resources for teachers interested in using such technology in their work.
