Coherence Principle #2

What is it?

The second coherence principle is the idea that graphics that are not directly needed for the material be taught to the learner should be avoided. These "irrelevant graphics" can hinder a learners ability to comprehend what is being taught and become a distraction in the lesson. These graphics do not improving learning and do not benefit the learner.  

Example:

In the image below you can see an example of the second coherence principle. The graphic may seem like it is helping in the overall aspect of the class, but this image has to much going on in it. The image is very distracting to the learner and will even take some things away from the overall lesson.
