Module Three Jigsaw Activity

Redundancy

collaborated with Tabitha Edenfield, Christine Wallo and Lori Oren


On the Web, find two multimedia pieces that violate your assigned extraneous cognitive processing principle. Provide specific examples and support them with references to your resources. Include a Web link to each site you selected. Each group member should find at least one example to share with the group. Your group can then work in one member’s wiki to discuss the examples and decide which two you think are best to present to the class. Then, as a group, select the two best examples to post in the Discussion.

1. This instructional video technically violates the provisions of Mayer’s redundancy principle, since it includes on-screen text, which the narrator reads aloud, as well as graphics. He provides a vast amount of graphics in the mathematical problem solving, which are appropriately narrated. The text, however, is not included with the same slide as the graphics, therefore, the student is capable with dual channels to manage both oral input, and graphic (visual) input at the same time.

2. This mathematical video is all-inclusive. The author has posted a mathematical equation, a text, images, and narration for the slides. The images, and text appear to be competing for learner visual focus, as the teacher narrates the working of the equation as a graphic representation. Here, the author violates Mayer’s redundancy principle.

3. This is an excellent example, in a literature skills, which might ordinarily tend toward redundancy. Here, the author has limited text to one word, or a short phrase, but has a vast number of visual images to support his narration.

I think that this presentation violates the principle of redundancy because for the most part the presenter is reading the same information that is printed in the Power Point. While there were a few graphics in the presentation it was mostly comprised of text and narration. To adhere to the principle of redundancy the presentation would be constructed using graphics and narration for the most part for maximum effectiveness. (Mayer, , p 118) There were places in the presentation where the presenter stopped to allow the viewer to read the text but the effectiveness of this is likely no different than when they viewers read from printed material. Reading from a presentation may even cause added stress for the viewer because of the need to rush to finish the passage before the slide is changed. This could have been presented with more graphics that could be elaborated upon by the presenter instead of reading the text with minimal changes in verbiage.
