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.
