Week 4 Readings
I think that the best way to present the multimedia and contiguity principles to my colleagues would be to demonstrate contrasting good and bad examples. Since PowerPoint is likely going to be the medium of choice for many of them, I would also show them a short YouTube video from Guy Kawasaki where he explains his 30 20 10 principle. It's a great way to sum up the best practice for text on PowerPoint slides.

As for the contiguity principal the authors, Clark and Mayer (2008), explored two techniques of this principle and summarized them nicely on page 93-94. This link shows how I would explain it to a colleague:

The Atkinson and Mayer article, Five ways to reduce PowerPoint overload, reminded of another article I read called PowerPoint is evil by Edward Tufte which can be read by following this link: http://www.wired.com/wired/archive/11.09/ppt2.html. It also appeared in the September 2003 issue of Wired Magazine. I’m proud to say that I have always taught my students to make their PowerPoint slides short and sweet. Use words that make the point right away and images that represent the words. Now, with Web 2.0 tools galore who needs Power Point (sorry Bill Gates).
Week 4 Readings
This week’s readings were very good and applicable immediately. I think most people, at least to a degree, have suffered from PowerPoint overload. We have been on the receiving end of it and have probably made more than a few students endure our own presentations that were, in hindsight, poorly put together.
The way I would go about defining and demonstrating these principles is, oddly enough, a PowerPoint presentation. I think it is important to show a good and a bad way. I would design a presentation that explains each of these principles, using the proper principles of course. After each point, I would take one of my own presentations for my classes and show both the traditional (or old fashioned or wrong ) way of presenting the material. I would explain why it was not a good slide Then, I would contrast that slide with one following the proper principle we were discussing at the time. At that time, I would try to encourage discussion on why the new slide is better than the old slide.
To close, I would explain to my colleagues that we have got to re-evaluate how we are teaching. When preparing a lesson, we have got to have these principles in mind and constantly eliminate the material causing an extraneous load on our students. In combining that line of thinking with these principles, I think our students would have a better overall learning experience
Week 4 Readings
The most concise way to explain these points to a colleague is through the phrases, 'less is more' and 'keep it simple'. All the principles discussed this week lead to reducing the amount of 'stuff' in a presentation, whether it is background images, text, extraneous information, not pertinent images, etc. Multimedia presentations need to be the minimum amount of 'stuff' needed to convey the necessary content. For example, a presentation slide with a heading and a pertinent graphic that serves a purpose past decoration simultaneously accompanied by spoken information should minimize cognitive overload.
PowerPoint type slide presentations are the most frequent offenders of these guidelines. I have seen many slide presentations that violate most of these principles. As the article stated, the abundance of cluttered slide presentations is due largely to the program and how it aides the creation of cluttered slides. I am certain that I am guilty of many of these presentation offenses.

Week 4 Readings - Christina Talley
Week 4 Readings
Chapter 4 on the Contiguity Principle contained some solid information and examples about keeping text close to graphics. Likewise, the Atkinson and Mayer article on principles for Powerpoint design was clear and straight to the point. I am looking forward to reading more about the Modality Principle in the next chapter of ELSI, because I happen to prefer to read text on screen than to listen to narration. If I have the option of a transcript or audio, I will choose the transcript.
