The Coherence Principal is the idea that humans
can only process so much in their working memory. By overloading instructional
materials with redundant or unrelated visuals, audio effects, and background
music, learners will less successfully be able to grasp the concepts and ideas
the instructor wishes to impart.
2. Describe
and/or include one example of successful and one example of unsuccessful
attempts to apply the Coherence Principle in actual instruction and training
you have experienced, especially as it might be implemented in PowerPoint-based
instruction and training. Have you ever seen this principle violated or abused?
Identify the violations, including citations as needed from your textbook.
The first was that his presentation contained extraneous text. It was also set up in such a fashion that what was written on the slides was almost word-for-word what he was saying. The slides were dense with text and poorly spaced. It would have been more effective if he had paired his speech with relevant visuals and a couple of choice words. Sentences upon sentences of text on a PowerPoint presentation is always a bad idea.
The presentation did contain one visual, but it didn’t seem to be directly related to the material on the slide. I can’t remember what the image was, or what the material on that slide was about. This is likely because the image disrupted my ability to build an appropriate link to the material (Harp and Mayer, 1998).
An example of a successful presentation was one I saw today in a workshop I attended at the Technology and Literacy at the Beach conference in Myrtle Beach, SC. The presenter, who was speaking about social media tools in the classroom, had a PowerPoint slide that contained four words and a picture. The picture related directly to a point she was making about collaboration, and helped me to understand what she was talking about.
3. Discuss
the relationship of the Coherence Principle to other Multimedia Learning
Principles examined thus far in your readings.
4. Discuss
the relationship of the Coherence Principle to fundamental theories of psychology
as described by Clark & Mayer in your textbook.
5. What
do you personally like or dislike about this principle? Present a coherent,
informed opinion and explain why you hold this opinion. Are there any
limitations or qualifications of the principle (caveats) which the authors did
not consider and, if so, what are they?
I personally find it enjoyable to do work while listening to classical music. I’ll often play it in my classroom at a very low volume. Students say they enjoy it, so it’s something I’ll usually put on when students are doing independent work. I wonder, though, after having read this chapter, if that music is a hindrance, resulting in writing tasks taking more time, as the text suggests. I've be curious to do my own research experiment to find out.
