Coherence Analysis

Here is a link to view the original Google Doc.

One of the course activities in EDTECH 513 – Multimedia requires learning about and demonstrating working knowledge of the Coherence Principle. This is achieved through the process of conducting a coherence analysis on at least one multimedia e-learning artifact that is not in compliance with the Coherence Principle and then rendering a revised and compliant version of one of the artifacts.  First, it is important to understand what the Coherence Principle is and how a coherence analysis is conducted.

The Coherence Principle, as it relates to multimedia, states that “information in the form of added text, added graphics, and background sound” should not be included in e-learning artifacts (Clark & Mayer, 2016, p. 152). This means all of the swirling transition effects, sweet graphics, and boing-boing sound effects that are available to dress up any mundane PowerPoint are, for the most part, forbidden in the interest of creating e-learning materials that are truly supportive learner success. A coherence analysis is the process of evaluating an e-learning presentation to determine if its design aligns with the requirements of the of the Coherence Principle concerning extraneous or unrelated text, graphics, or sound.

My daughter, K, is in elementary school. She is an inquisitive child and always full of questions. Lately, she has been very interested in anatomy, especially the human eye. Because of this curiosity about the human body, I have spent a lot of time looking at resources about eyeballs.  It should come as no surprise, then, that I decided to conduct a coherence analysis on e-learning artifacts on the human eye.

I analyzed two artifacts that provided information about the human eye: one animated video and one static slide from a SlideShare presentation. The subject matter was the main connection between the two artifacts, not the presentation style. As the father of a young learner I wanted to investigate an artifact aimed at children and, as an academic librarian, one aimed at older learners.  The animated video was directed at young learners. It contained many violations of the Coherence Principle in the form of extraneous graphics, distracting animations, background music, and unnecessary text. The static slide was slightly better. The violations present on the slide pertained to extraneous text and complex graphics where simple graphics would have produced less visual noise for the learner. Here is the original static slide.

I revised the static slide in order to make it compliant with the Coherence Principle. I limited the text, reduced the number of graphics, and used a simpler graphic to represent the eye. Additionally, the revised text was added in alignment with the Contiguity Principle, which states that text should be placed near related graphics. Here is the revised slide.

Coherence Theory compliant

The exercise was very beneficial to expanding my understanding of the Coherence Principle. I also enjoyed deconstructing an artifact and making improvements to it that enhance its usefulness to learners.

The creation of this artifact meets AECT standards 1.2 – Message Design, 1.3 – Instructional Strategies, and AECT Revised standard 1.3 Assessing/Evaluating.  I demonstrated competence in the area of message design by analyzing existing e-learning artifacts, deconstructing them, and revising them to meet learner needs according to research-based principles. Additionally, the activity required me to consider the appropriate instructional strategies to use in delivering e-learning content to learners. Finally, the process of conducting a Coherence Analysis and revising the static slide provided me with the opportunity to effectively integrate the e-learning materials into a Google Document for distribution to learners.

Until next time, keep reading!

The past two weeks in EDTECH 513 we have been learning about more multimedia principles. Our class broke up into groups for some collaborative work. Each group was tasked with creating a Google Slides presentation, converting it to a PDF, uploading it to VoiceThread, and narrating the presentation. The final product is a multimedia presentation that adheres to the Modality Principle and the Redundancy Principles. Let’s unpack these terms a bit.

The creation of multimedia artifacts that are both visually appealing and pedagogically sound takes time and study. The ability to craft a compelling presentation is not something that happens magically or intuitively. Research-based multimedia principles offer substantial assistance in the development of expertly crafted multimedia content. Two such principles are the Modality Principle and the Redundancy Principles. The Modality Principle states that, when graphics are present, it is best to provide audio explanation rather than printed text. The Redundancy Principles take modality one step further and discourage the use of redundant information in the form of graphics/text/narration. This redundancy causes an overload of the learner’s cognitive channels. This understanding of cognition runs counter to the old wisdom grounded in “learning styles” which, in the case of a presentation, could lead to a potpourri of information with something for everyone: graphics/text/narration. Of course, there are exceptions to these rules, as there are with any stated regulations. In this case, the exceptions are known as boundary conditions.  These exceptions come into play when there are no graphics, when the materials are slower or learner-paced, where there are technical terms, or when the on-screen text is genuinely shorter than the narration.

When I was in high school and college as an undergraduate student, learning styles provided the basis for many sound pedagogical practices. I was presented with many lectures that included lots of text (gotta deliver that content!), an abundance of graphics (because – Hey! – the kids like pretty pictures!), and narration (I’m the teacher. I have to do something). Far from helping me learn better, these practices served to create a lot of psychological noise for me. I would get lost between the graphics, on-screen (overhead) text, and the teacher’s voice. Sometimes the teacher would go off on tangents, thus making it especially hard to know what to attend to.

In the past, I have been guilty of trying to do too much with PowerPoints and other lecture material. I would fade graphics and use smaller fonts in order to cram as much onto a slide as I possibly could. More is better, right? It gives students the option to learn the way that works for them. The ol’ shotgun approach to information delivery. Oh, how wrong I was! Now that I have learned about the Modality Principle and the Redundancy Principles, I can appreciate the value having less on a slide brings to my students, pedagogically speaking. I have begun using less text and, with the text I do provide, I strive to reduce the text to the very essence of what the students need. The adoption of multimedia practices that adhere to these research-based and proven principles will greatly benefit my students.

The creation of this artifact meets AECT standards 1.2 – Message Design, 1.3 – Instructional Strategies, 2.2 – Audiovisual Strategies, and 2.3 – Computer-based Technologies. First, this artifact meets AECT Standard 1.2. As with the multimedia tutorial I created using HaikuDeck, we followed a systematic method in the creation of this presentation. My group collaborated on the draft of the presentation in a Google Doc and used email and commenting to work out the details. We selected images from stock files in order to communicate our message about the Modality and Redundancy Principles.  We also relied on narration instead of text, instead using on-screen text in carefully controlled amounts. The result was a well-designed message that is aligned with research-based multimedia design principles.  Second, regarding Standard 1.3, we utilized the instructional multimedia design principles of the Modality Principle and the Redundancy Principles, making sure to only violate these rules when appropriate based on a thorough evaluation of the relevant boundary conditions. Images were thoughtfully selected and used as the primary means of communication along with narration.  Text on slides was kept to a minimum, except in the case of example slides. Third, Standard 2.2 was supported because of the use of audio and graphics to present a message that is based in solid multimedia research. Fourth, in support of Standard 2.3, we used Google Docs, Google Slides, and VoiceThread, all web-based software applications, to create the presentation. Finally, I distributed it by embedding it on my WordPress blog.

This activity also meets the revised AECT Standards 3.1 Creating, 3.2 Using, and 4.1 Collaborating. 3.1 Creating: Candidates create instructional design products based on learning principles and research-based best practices. I created a multimedia presentation that adhered to the Modality and Redundancy Principles. 3.2 Using: Candidates make professionally sound decisions in selecting appropriate processes and resources to provide optimal conditions for learning based on principles, theories, and effective practices. I used a draft process with my group that involved Google Docs and Slides. Once the drafts were finished, I created a PDF and uploaded it to VoiceThread so my group could add narration and finish the presentation.  4.1 Collaborative Practice: Candidates collaborate with their peers and subject matter experts to analyze learners, develop and design instruction, and evaluate its impact on learners. I collaborated effectively with my group members to analyze the needs of our anticipated learners, developed the instructional presentation that met multimedia design requirements. We also considered the impact our instructional materials, both content and design, would have on potential learners.

Until next time, keep reading!
