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.
Boys are better at technology than girls. It is too difficult for small children to use the computer. Students should only use the computer when they are finished with their regular work, as a reward. The basics of reading, writing, and arithmetic are not part of technology integration. One day of professional development will be enough.
