3 Brief Description of PowerPoint Predecessors include overhead presentations and working with Genigraphics 1987: PowerPoint 1 Originally names “Presenter” and designed by Forethought of Sunnyvale, CA Ran on a Macintosh and was only in black and white 1988: Microsoft buys Forethought 1990: Windows version released. Competitors included Harvard Graphics and Lotus Freelance.

4 Original Problems Buggy Poor support of fonts Changes to outline did not affect slides and vice versa.

5 Current Status Now the dominant presentation tool. “With more than 300 million users worldwide, according to a Microsoft spokesperson, with a share of the presentation software market that said to top 95% and with an increasing number of grade school students indoctrinated every day into the PowerPoint way - chopping up complex ideas and information into bite-sized nuggets of a few words, and then further pureeing those nuggets into bullet items of even fewer words - PowerPoint seems poised for world domination.” Why is it so popular?

6 Recent Criticism New Yorker, “Absolute PowerPoint”

7 New Yorker Comments Critical of auto-content wizard Misuse of bulleted lists “Because PowerPoint can be an impressive antidote to fear—converting public-speaking dread into movie making pleasure—there seems to be not great impulse to fight this influence, as you might fight the unrelenting animated paperclip in Microsoft Word”

8 Recent Criticism—Edward Tufte Professor at Yale University Renowned expert on how to present information in an effective manner

10 Recent Criticism—Edward Tufte 2003—The Cognitive Style of PowerPoint

11 “PowerPoint chart junk: smarmy, chaotic, incoherent”

12 Tufte Suggests Stay away from Content Wizards and Slide Templates. Use printed materials. PowerPoint does not provide the information density necessary for many talks. This is especially true when using bullets. Stay away from PowerPoint Chart. Use as an adjunct to the presentation and not the presentation itself. Do not use builds!

14 Students Comments PowerPoint Enhances Student Learning When the lecture notes are available in a timely manner When slides are not overcrowded Because slides are sometimes more legible than handwritten overheads Because they help identify the lecture’s main points

15 Students Comments PowerPoint Detracts from Student Learning When notes are not available in time to print before class When the slides are overcrowded and confusing When professors read directly from the slides When professors do not take the time to draw diagrams and explain the processes involved.

16 Recent Responses March 2004 “Does PowerPoint make you Stupid?”— Tad Simons Good summary of Tufte’s comments and rebuttal Describes disconnect between what Tufte has previously and his current “tirade” Builds and layering can be educational useful. Tufte misses the fact that PowerPoint presentations can be emotionally effective.

17 Recent Responses The Cognitive Load of PowerPoint: an Interview with Richard E. Mayer Too often, speakers are interested in presenting information only and are not interested in the cognitive processing Important to separate media and methods. Media refer to the delivery systems for communication. Methods refers to the instructional design.

18 Mayer Dual-channels: people have separate information channels for visual material and verbal material. Limited capacity: people can pay attention to only a few pieces of information in each channel at a time. Active Processing: people understand the presented material when they pay attention to the relevant material, organize it into a coherent mental structure and integrate it with their prior knowledge.

19 Mayer’s Suggestions Make use of dual-channel structure of learning A graph should have labels Minimize the chance of overloading the cognitive system Eliminate extraneous material, such as 3- dimensionality and cute but irrelevant clip art. Design the presentation to promote active learning by guiding the processes of selecting, organizing and integrating information. Use arrows, outlines, and concrete examples such as video.

20 My Thoughts Tufte is dealing hyperbole. Tufte has not taken the time to properly evaluate PowerPoint as an educational tool. He is correct when it comes to the low “information density” provided by PowerPoint. He is also correct about the linear nature of powerpoint. Builds can be effective.
