Somebody asked for advice on the Irish Principals’ Forum about getting a visualiser for their classrooms when they already had IWBs. They were wondering was there any point in investing in the visualiser at all. I thought it might be helpful to point out the differences between the two.
A Visualiser does a different job to an Interactive Whiteboard. Both are teaching tools, in that they are generally more used by the teacher than the children. However, children can and should use them.
A visualiser is basically a digital camera on a stand. When you plug it into a projector, whatever is in the visualiser’s view, appears on the big screen. The teacher or child can then move the objects they need.
An Interactive Whiteboard when attached to a projector shows whatever is displayed on the computer screen. The teacher or child then can interact with what is on the screen using a finger or magic pen.
So, they both do different jobs and teachers seem to be very excited by both. Luckily (excluding the cost of the projector) a visualiser can cost as little as €80 whereas the cheapest commercial IWB starts around the €400 mark.
