My background is as a lecturer of sport science. Sport science students have a tendency to be energetic, lively and not always the best behaved – they also have a tendency to be competitive. I often used this competitive nature to my advantage to try and channel their energies into the desired work, rather than disruptive behaviours, and one tool that I used was score ladders which I dropped into a PowerPoint presentation – this is a simple mechanism for keeping score between 2 to 6 teams on any activity (who can solve a problem first, or answer a question quickest etc), and these ladders can be used by anyone in education – and all they need to be able to do is copy and paste. This video will show how.
