I was reading this post on Assorted Stuff about research into the use and effectiveness of Powerpoint in Education.
I completely agree with the conclusions that the effectiveness of its use comes completely down to how it is used. In my school this can be seen best during whole school assemblies where most staff who lead them use Powerpoint. The effectiveness of these completely vary, from those that put on the screen everything they are going to read, those who put things that are disconnected, and those who put things in the presentation that enable the pupils to engage with the topic.
I have been guilty of this in the past, but Powerpoint should not be used as a break from the information, a pointless use of media, nor a restating of everything said during the lesson. When used properly, they can be a fantastic way of engaging pupils in a topic, conveying key information easily and quickly, and also a way in which pupils can be taught using all their different learning styles, (Visual, auditory, verbal and physical).
I had a conversation with my father-in-law recently about a talk he gave to his school about how to use PowerPoint and he mentioned the “10-20-30 Rule of Powerpoint”. Basically put, this means if you are going to talk for 30 minutes, you should optimally use 10 slides and be talking for 20 minutes to give enough information about each slide, you should also allow 10 minutes of questioning at the end, and not use a font size of less than 30 so as to use the space effectively. I think back to how many lectures and teacher training courses I have been to and about 90% of them ignore all these ideas and rules.
If only that “10-20-30 Rule of Powerpoint” could be passed on to all that use it. Hey, maybe I should contact Microsoft and see if they could include it in a Vista update
