The tenents of CLT need to be shared with staff, young and old. This will assure that all are aware of the need to take an audience into consideration when making presentations to an audience of any type.
I think that the presentation that I will use is one where slides are shown as a before and after. Download a few slide shows from google or slideshare and edit them through the CLT lens. By showing the differences after making changes to fall in line with the ideas of CLT, perhaps some will see the differences and adjust their presentations accordingly. Technology used in education to present information, to adults and kids alike, need to be ulilitarian. In other words, if there is no need to have the fly-in, the graphic or the fancy background, then do not include it; especially if the pretty takes away from the meaning of the slide. The graphics in a presentation is not the reason for the presentation; the content of it is the reason.
