ICT in Schools

Visualiser

Enabling teachers to teach

A visualiser, sometimes called a digital presenter, is a digital device that has connections to both a computer and a projector.

It consists of a stage, some lights and a camera mounted on a stalk.

Items put on the stage can then be projected straight onto a large screen via a ceiling mounted projector, or the image can be captured by the computer and then annotated using interactive software tools.

The visualiser has controls that enable you to zoom in on the image and display objects at very high magnification.

The device automatically corrects the focus and the brightness, making it very easy to use.

Teachers can show small objects to the whole class at the same time.

Every book can become a big book, and a demonstration of some intricate skill or technique can be seen by everyone at once.

Pupils can show the rest of the class their work, or model an activity.

Barking and Dagenham schools use the Samsung 950 series, which now have a fast USB2 connection to the computer enabling a live demonstration to be shown in a computer window.
