I would be very interested to hear from others teachers whether they feel that IT can overshadow the real objectives of a lesson and while powerpoint presentations look impressive, do they really aid learning. Are we getting better results now than we did 10 - 15 years ago when we had little or no IT in the classroom.
I think that often the most valuable technology is the kind that is almost invisible- the power of forums is their ability to allow you to contact such a wide range of interested people, the technology merely provides the platform.
This assumption that you mention is also held by The British Council and OFSTED who, on inspection, expect to see IT being used it the classroom regardless. I do use an interactive whiteboard in some of my classes, but feel that the lesson is only as good as the lesson plan and while you may use a collage of pictures to launch a topic on the IWB, cut outs from magazines serve the purpose just as well. I taught in China 15 years ago and had no IT, not even a photocopier, and my library of pics was ragged and tatty. The students loved looking through them and learning took place. Now, our students expect the all singing dancing hardware in the classroom and I believe it can get in the way of actual teaching as the teacher fails to actually get off the platform you mention and get on with the task iin hand.
