At one point in our course we went over what made a good presentation. This reminded me of a lesson my co-operating teacher gave while I was student teaching. It was for a biography project where the students would present someone they had researched.
This is the link to the presentation the lesson was based around:
www.iasted.org/conferences/formatting/Presentations-Tips.ppt
[WARNING: It contains, possibly, the worst powerpoint slide ever created. View with caution.]
I know I've been more conscious of slide design since I went through this.
