ABSTRACT
That computer technologies change and evolve more quickly than books about them can be published is an obvious fact. But educational use of computer and telecommunications technologies, or at least widespread take-up by institutions, is much slower, so that it is possible to discuss current delivery technologies and speculate about trends with some degree of certainty about the direction, if not the details, of global education delivery media. As I mentioned in the previous chapter, it is distance education, as presently practised usually on a national scale, which is the forerunner and first pioneer of global education. It therefore makes sense to study the technologies in use today, in order to assess the benefits and limitations of various media for the global education of tomorrow.
