Interactive whiteboards are probably the best advance in creative delivery using ICT since computers were actually first introduced into the classroom. They can do so much, and it's well worth contacting your IT department and seeing if you can get on board (groan) with some training.
There are four components: a computer, software, a projector, and a screen. You can write on it like a standard whiteboard, but with the added advantage that you can call up graphics, capture on-screen notes, have games - in short, a much more diverse lesson can be created. You can have several 'pages' on the go at any one time, which means that you don't have to keep flipping back to previous flip-chart pages, or having to rewrite stuff you've wiped off a standard whiteboard. You can also have a 'blind' which you can have over the display to reveal sections of your screen bit by bit - just like using a piece of card to cover aspects of an overhead projector transparency.
Some of them also have a facility where you can have a look at what's on your learners' monitors. If you're also projecting at the same time this can cause some red faces! It's a very handy facility if you have a large class going on and you want to check that your learners are actually doing their work and not hanging out on Facebook.
Some let you 'project' your own display onto the learners' monitors, which is great for giving demos.
The two market leaders are SMART Technology's SmartBoard and Promethean's ActivBoard. Hitachi also do one called the Cambridge Board.
Students are increasingly tech-savvy and will have used these in schools. All primary schools in the UK now have them, and 98% of secondary schools. Learning is definitely enhanced by using them. You can have a much wider range of learning materials to call on, which also can be a lot of fun for students. You can go here for a great guide on what they can do to help you in the classroom. It's a downloadable pdf.
Heh - good question.
