Yes I tend to agree. I have to be careful because I'm 51 years old, come from a commercial IT background and have been teaching SEN for only 3 years to date. We are trying to give our under 10s at least 1 hour a week in the computer room and to tie the moodle activities into the existing paper based classroom material.
I'm not a psychologist, but I have a feeling that there is some aversion from those colleagues who have personal difficulties with the technology. This is actually the case in the examples I reported on.
One situation involved the distribution of a photocopied article in the staffroom "Studies have shown that the virtual world damages our kids" and that may be true, as you say, with mindless video and games. In my mind, a few hours a week with constructive material must be positive.
Last year, I had several classes under 10 for introductory lessons in the computer room. My first question was always "Who has a PC at home and what do you do with it?". The answer was always "play games", "surf" and NOTHING else! If we ban computers in the school, they will still do that. On the other hand, a nine year old was thrilled to report that he had produced something meaningful with Excel at home and, in that particular case, that would certainly not have occured without the school contribution.
We tend to forget, that there are a lot of colleagues who have absolutely no idea what a WIKI is and for whom the whole ICT concept is very threatening. Any justification, for not joining in would in that case be welcome.
On the other hand, we have to be careful not to the enjoy the technology for its own sake. To quote the Times Educational Supplement on teachers and ICT recently, "Oh sir,do we really have to play super mario again!"
