Learning how to use educational technology to do collaborative projects is first and foremost a technology issue. The teacher has to be a technical expert. Users must know how to use a keyboard. Every classroom needs a computer.
Technology is an impersonal solitary activity.
Communications on-line are virtual and not real. There is no social context to the Internet. Assessment and evaluation are only done at the end of an assignment. The teacher is the source of knowledge. Interdisciplinary themes are too difficult to plan.
