In education, our goal is to try and offer as much information to our learners as possible and to help them retain that information in order to use it in their futures. However, as mentioned by Richards Meyer in The Cambridge Handbook of Multimedia Learner, “if [we] overload the working memory before there is time for encoding and long term storage in mental models, things will be forgotten.” (Mayer, 2021). Therefore, it is imperative that we begin to analyze how people think and learn so that we can design presentations that will give our learners the greatest chance to acquire the intended information. If we begin using aids such as images and videos and The Principles of Multimedia Learning, we will enhance our chances to facilitate the long term storage of information.
By addressing the Dual Coding Theory while designing powerpoint presentations, or any presentation for that matter, we can “manage intrinsic load, optimize germane load, and minimize extraneous load to ensure maximum storage in long-term memory” (Mayer, 2021). That means that we can bring focus to essential material by scaffolding the information and by deleting all the needless distractions. We can use only simple visuals, graphics, text and narration that support learning goals. We can ensure there are images to support words or text in hopes to connect to our learners and give the information meaning, at the same time as being aware of needless images or text which could distract them from the intended outcomes. Finally, we can highlight and guide their focus by using arrows, highlighting and fading functions within programs.
I have taken part in plenty of “death by PowerPoint presentations” (Philliips, 2014) and have become completely overwhelmed by the amount of information that is put on one page. I have seen how bullet points are followed by sentences and how twirly texts and images that have no tie to the actual information are being used in hopes to gain or keep my attention. These additions, in fact, had me guessing at what I was supposed to know and made my brain hurt, which either led me to guessing where to look, or shutting down my efforts completely. I also noticed how I would slump into my chair and become completely uninterested and unmotivated to learn. These sessions were missing engagement with the materials and with other people. A brainstorming activity, partner chat, personal story or video to deliver another avenue would have greatly increased my attention, retention and motivation to learn about the subject matter, since I would be participating in it. I would have felt part of my learning which would be much more effective at grabbing and holding my attention than a twirly text. Using brainstorming, partner chat or multimodal avenues would have allowed me to share my thinking, learn new understandings/misconceptions by attaching the new information to my prior knowledge and it would have allowed for me to connect to and with the material in more modalities than that of speaker and text. For these reasons and more, I will be taking The Dual Coding Theory and its principles into consideration every time that I design a learning object for my learners.

Omar,
Thank you for such a thoughtful post. I appreciate how you laid out your experiences and then spoke to how Dual Coding Theory could have helped thereafter. You mention, “there’s no need for additional explanation, proofs, weird symbols, colours/symbols that do not match. This will only serve to distract the learner at retaining the most important points.” I absolutely could not agree more. I teach Kindergarten and the more things I place on the screen, the less the learners retain since their attention is then everywhere, rather than where it ought to be. After analyzing your powerpoint, I wonder if I have placed too many videos in my powerpoint thus “muddying” the actual concepts which I hope to get across. That being said, although it could be an overload, it is also the modality principal of how people learn better from oral and image rather than text and image. It is difficult as I have non-readers and everything must be orally explained and visually demonstrated. What do you think about this? I would love your feedback on my Prezi and regarding this question. Thank you again for such an insightful post. It definitely sparked more wonder and curiosity in me.
Glad you worked it out! As you say Dual Coding Theory is one that has potential to impact how we deliver content in PowerPoint or really wherever.
Jayne,
Thank you for the insightful post! I enjoyed how you first began by discussing the main goal of education, and the importance of understanding how people think and retain information in a classroom setting. I could not agree more with your point on utilizing aids for all learners. I strongly believe that in order to increases our chances of long term retention, we must start implementing more images, videos, and the follow the fundamental principles of Multimedia Learning. Furthermore, your discussion on Dual Coding Theory is fantastic. You clearly express the Dual Coding Theory is all about simplicity, and the need to cut out images or text which could distract the learner from the intended outcomes. A very nice transition into the next part discussing the mess that PowerPoint can create when creating presentations. I completely agree with on an engagement piece that would have kept you focused. I learn the same way, I need something, as you said to “grab and hold my attention” because if not, no focus whatsoever. The ability to represent information in different ways is powerful, and in most cases is needed for people to effectively retain information.
Also, you’re Prezi was fantastic and simple! Only displayed relevant information and wasn’t cluttered. Also have to mention, I really appreciate the bear photos you included, very adorable.
Thanks!
