PowerPoint can is an oft maligned piece of
software, and I am often the one maligning it. For a bit of history... In the field of Educational Technology, we have known for some time that providing redundancy between what people are hearing and what people are seeing is a good thing. The research on this redundancy is known as multiple channel communication (the simultaneous presentation of related stimuli) or cue summation (providing multiple visual or auditory cues within a communication channel). Historically there has been much research done on multiple-channel communication and cue summation. Moore, Burton, and Myers (2004) provide an exhaustive review of the literature on both. At the risk of oversimplifying this review, we can say that on the positive side multiple-channels of information may provide greater enrichment in learning. On the negative side it may lead to cognitive overload for learners. For many years we used overhead transparencies to provide this information to learners. And in the days before computers made it easy to make compelling transparencies easily and affordable, creating overhead transparencies was very resource intensive. For example, to letter a bulleted list in a professional font (or not hand written) you needed quite a bit of time and patience. This might have meant rub-off letters, or tracing stencils to create a professionally produced transparency. If it took that kind of effort to create a slide, then you were not likely to create many of them. At the risk of sounding like I am waxing poetic about the good old days (because they aren't all that old, and they weren't all that good), you had to make your visuals matter. PowerPoint changed all of that. Suddenly, it was remarkably easy to create slides. You could put images and text on in a matter of minutes. And here is what that meant: a thirty minute presentation, back in the day, might have six slides, or five minutes per slide. Today a thirty minute presentation may have thirty visuals, or one minute per slide (I know you can do that math, but I am trying to make a point). We refer to this as a "slide whipping." Here is my premise, and it may be mine alone, the ability to create slides quickly and easily has led us to create many bad slides. I am as guilty of it as anybody. We tend to create slides (and presentations) that suffer from the following problems:
PowerPoint has become, to many, a parody of itself as suggested by the Doonesbury cartoon below:
PowerPoint has many, many benefits. But what we must do as educators is reclaim the power of the redundant visual and maximize the power of the software. To that end, here is information on the use PowerPoint in its traditional and most commonly used use, as a presentation support tool. I also provide here information on PowerPoint as a media development tool. If you are reading this as part of a general information exploration, welcome, and please send me feedback. If you are reading this as part of a class, wait for the assignment.
Presentation support tool Tips for better presentations are provided by many people. Below are some of the ones that I find useful.
Media Development Tool PowerPoint can also be used as a media development tool. It provides many affordances to make it a useful, if at times basic, media authoring tool. For example, using PowerPoint we can:
While the authoring functions may not be the most sophisticated, the ubiquitous nature of PowerPoint coupled with its relatively short learning curve, makes it a useful option in classrooms as a tool for students to build meaningful representations of what they know. Here are some examples of PowerPoint being used as a media development tool. Claymation Digital Story Telling
