Take your phone out and have a look at it. You could use it to hammer in a nail. You could use it as a coaster for a hot coffee cup. You could pop it under a wobbly table leg to balance it. You could, but you wouldn’t because it really is not the right tool for the job. The only purpose for a presentation (p2) file is as supportive media to your presentation (p1).
There is no place for using a presentation as part of a summative assessment demanding it is full of data and references. That is a word document. There is no place using a presentation as a handout. That is a slideument. There is no place using a presentation as a script. That is just wrong. There is no place sending a presentation as an email attachment to someone who couldn’t attend the presentation (p cubed). That is a video. There is no place using a presentation as a poster. That is a publisher file.
The stuff that goes onto slideware is supportive media (p2) for the delivery (p3) of the story (p1), nothing else.
