Educational Technology – an add-on?

In a recent blog post, Larry Cuban sets out his interest in exploring examples of technology in action in real schools and with real teachers. Something I have been doing for a few years. In his post, he writes:

One that has bothered me for a long time is why “technology” in education is considered separate, an add-on, when that is not the case when observers look at technological tools applied to business, medicine, architecture, engineering and other professional work. For some reasons in these other domains high-tech tools are part-and-parcel of the daily work that professionals do in getting the job done well.

An interesting observation, and true to an extent. Why is ed tech often seen as an “add-on”? Should it be?
