Teacher training is an essential component of the use of technologies. The phrase"information infrastructure" has an expansive meaning; the technology includes more than just the physical facilities used to transmit, store, process, and display voice, data, and images.

It encompasses a wide and ever-expanding range of equipment that includes cameras, scanners, keyboards, telephones, fax machines, computers, switches, compact disks, video and audiotape, cable, wire, satellites, optical fiber transmission lines, microwave nets, switches, televisions, monitors, printers, and much more.

It could be a daunting experience for teachers to have to convert their practices without support, engagement, evaluation, exploration, initiation and guided practce.

Often the initial steps of learning require a lot of thinking about classroom practices in delivering
content. Since content is not static, as in a book,
there is often a lot of information that may be new to the
teacher in the content areas.
