Focus on engagement
You can know your subject inside-out, use the best metaphors and diagrams you can muster, but if students aren’t engaged in your lesson, very little learning is going to take place. Play games with them that test their understanding of topics. I love, for example – and this is very relevant to this post – Game Show Presenter. Cheesy, but fun! Another favourite is Andrew Field’s marvellous ContentGenerator.net products, some of which are free.
Game Show Presenter comes at a price. Another site I looked at in passing recently was www.classtools.co.uk I’ve used their countdown timers a few times (great with the ‘Countdown’ theme tune) but I really must take time to give their site a proper look.
