Coherence Principle
According to the book, Proven Guidelines for Consumers and Designers of Multimedia Learning, Coherence Principle simple states to "avoid any material that does not support the instructional goal" (Clark, Mayer, 2016). Take a look at the photo above? At first glance you may notice it is a bear. There is a tongue and ears, a nose and eyes. If you look at it long enough you will see the different shapes patterns and colors that are also there. This graphic is eye-catching but is not be the right choice when designing an informative e-learning unit about bears. The graphic is overly busy and distracting. The graphic also does not contribute any knowledge about the topic of bears. Therefore, this graphic would not support my instructional goals.
Extraneous Text Graphics & Sound
According to the Coherence Principle, when designing e-learning multimedia products we must avoid extraneous text, graphics, and sound that does not support the instructional goals. There are broken down into three principles. Each principle gives guidance and how and why we should avoid extraneous material. Text, graphics, and sound should all be relevant to the topics at hand so that these elements don't distract the learner from informative material.
Applying Coherence Principle
In the paper above I discuss two instances. Once where I successfully applied the Coherence Principle, another where I didn't even attempt to apply the Coherence Principle at all. During my successful attempt I used the help of Artificial Intelligence (AI) as I created daycare scenes and preschool instructors. I knew my intended audience would appreciate seeing themselves in the presentation.
Coherence & Multimedia Principles
In the analysis paper I describe the relationship between the Coherence Principle and the Multimedia Principle. I believe both principle discuss layout and supporting instructional goals. Lastly, I reflect on any oversight I experienced while analyzing this principle such as principle three - avoiding extraneous sound. Who knew sound could actually be more distracting than I thought! This was the principle I needed most and its guidance has made me a better e-learning designer.
