Many schools are investing in Interactive Whiteboards. A lot of teachers are not using them to their full potential, mostly because of technical issues of calibration, software and hardware conflicts, setting up problems and most of all lack of professional development. Then there is the issue of 'Which should we buy for our school?'
Here is one example of Activboards being used in one school. The Activboard has the projector attached to the screen. (Big tick here, no projector or wires hanging from ceilings or sitting precariously on tables).
The screen can be moved up and down according to the child's height. The screen is large and can be seen by the whole class right to the back of the room. Teachers have very little problems calibrating because the projector is fixed to the screen. There is a wireless keyboard that children or teacher can use anywhere in the classroom. The only down was maybe the clarity, the room needed to be darker or the projector needed to have higher lumens, but it was a minor point as it made no difference to the children.
The Activboard works well in the Senior School because it can be seen from the back of the room and when you have big children sitting in a classroom with all your furniture, there is not a lot of room for sitting up the front. I also liked how you could direct student's attention to it while they are working at their desks and they could all easily see it.
