ABSTRACT
I am starting with what may appear to be an old technology for several reasons. Ever since the invention of the Gutenberg press, print has been a dominant teaching technology, arguably at least as influential as the spoken word of the teacher. Even today, printed materials, in the form of textbooks, dominate as the main technology of teaching in formal education, training and distance education. Why is this? What makes print such a powerful teaching medium, and will it remain so, given the latest developments in information technology?
