Substantive Post #1 Theories of Multimedia Learning

One of the most intuitive ideas for me in this module was Dual Coding Theory. As a student and in everyday conversation, I have consistently observed that combining text with an image makes the information easier to comprehend and retain. This feels so natural, which can be explained by the theory that our brains process verbal and visual information through different channels. I rarely rely on text when I consider how I learn. When studying, I frequently make diagrams or mentally visualize concepts, especially when the material gets complicated. This aligns with Schnotz’s (2022) explanation that learners construct mental models from text in a different manner than from images, and that, when done correctly, combining the two can foster a deeper understanding.

What surprised me more was the emphasis on cognitive overload, specifically, the idea that integrating text and images does not always result in improved learning surprised me more. I used to think that visual aids were always beneficial, but Mayer’s ideas, especially the Redundancy Principle, challenged this idea. I now understand how it frequently feels more annoying than beneficial to repeat the same information in different formats (such as reading entire slides while simultaneously listening to the instructor say the same thing). In the end, rather than promoting learning, those instances probably increased unnecessary cognitive load.

As someone with some experience with social media, inforgraphics etc. bring a deep understanding of how text and image are used to convey ideas quickly and emotionally. Memes are an excellent illustration of this; they convey meaning almost instantly by relying on quick visual recognition and little text. Although this is effective for engagement, the readings made it clear to me that this approach is not always appropriate in educational settings, particularly when more in-depth analysis is needed. My project design will be influenced by this experience, which will force me to take my time and consider more carefully why I am using an image rather than just whether it is visually appealing.

I pay close attention to coherence and contiguity when designing my projects. I would say contiguity would be hard to achieve, especially in digital layouts where timing and spacing are important, but coherence seems fairly simple to implement. Removing unnecessary content is something I already value. Segmenting also feels important, especially for learners who may not share the same background knowledge as I do.

Looking back, I have instinctively adhered to the principle of Dual Coding by using charts, diagrams, and other visuals to complement text-heavy content. However, I haven’t always followed the principle of avoiding redundancy. To reinforce learning, I often included text-heavy slides with narration. Moving forward, I want to be more intentional in selecting which channel, verbal or visual, should convey the primary message and which should serve as support, rather than repeating the same information in both.

All things considered, these readings changed my viewpoint from considering multimedia as a means of making content more “interesting” to seeing it as a cognitive design challenge. Respecting the boundaries of attention, working memory, and prior knowledge is more important for effective multimedia learning than simply adding more media. As this course progresses, I want to concentrate less on tools and more on how students actually process, integrate, and design information.
