Here are my examples of bad iliustrations of the coherence principle [|Bad example Coherence principle] In this lecture there are a number of extraneous visuals (the audience heads, the speaker's hands, the caption does not match the text on screen (which should I be reading), background talking...etc.

A second example is this week's vodcast -- see my comment in part 1 of this weeks discussion.

Here are my examples (Jeff):

My first example can be found at:

This Mayer’s coherence principle because it adds a great deal of interesting, yet unnecessary sounds, music, and pictures. This presentation is distracting, has a lot of bells and whistles, and fails to get its message across to the viewer, which, I am still unsure of.

My second example can be found at:

This violates Mayer’s principle because the presentation contains a great deal of extraneous words that, at times, do not correlate with what the speaker is saying. In addition, there is simply just a lot of extra text that is extremely difficult to follow while the speaker is talking.

 PLease edit as you desire! Once everyone is happy, we can post.

Mayer’s (2009) Coherence Principle focuses on the concept that people learn better when extraneous words, pictures, and sounds are excluded rather than included (p. 90). Here are our examples of multimedia sites that violate this principle.

 1. [] (Identified by Randy). Prezi is a powerful and engaging presentation tool. However, this one is simply sensory overload. Among the issues related to coherence are excessive amounts of extraneous, unneeded text (Summaries were far from succinct.), distracting visuals/effects, and interesting but, ultimately, irrelevant elements, such as images and videos. The overall effect is to leave the viewer overwhelmed by the intended goal (I think) of promoting an attitude of social change. This presentation should have been broken into several separate ones, for starters.  2. [] (identified by Jeff). This video violates Mayer’s coherence principle because it adds a great deal of interesting, yet unnecessary sounds, music, and pictures. This presentation is distracting, has a lot of bells and whistles, and fails to get its message across to the viewer, which, I am still unsure of.  3. [] (this week’s vodcast). (Identified by Debbie). In this Vodcast, while Mayer is explaining extraneous processing, specifically his principle of coherence, there is a mismatch or lack of coherence between what he is saying and what is presented. During his presentation the background is in constant motion with a panoramic laterally moving multicolored, blurred image that changes to a series of flipping tiles, to a series of images moving from back to front. These images while blurred are in color with just enough definition to draw the eye. Between the movement, changing size and colors, I found my eye (and brain) drawn to them, trying to figure out what it was.
