When creating my
digital story, I followed Mayer’s multiple principle as stated in Swisher’s
article using graphics to enhance student learning as well as illustrations that
explain the process involved in creating note names as a mathematical function. Swisher also discusses in depth Mayer’s
principle of modality in which material is presented both as visual respresentation and
auditory narration. This process has been proven to increase working memory capacity; therefore, hopes to aid
in transfering information into long term memory.
This would then in turn reduce the cognitive load needed to process new
ideas. It is also noted in Swisher’s
article that when words and pictures are presented at the same time, it is
processed by both the verbal and auditory channels as studied with dual
coding. As warned, I was careful not to
include text in addition to narration and graphics, falling in line with redundancy
and overload included in the modality principle.
One other piece I was
careful to pay attention to when creating my slides and narration was the
temporal contiguity principle. The temporal contiguity principle is related to
the split-attention effect but focuses on the physical relationship between narration and
animation. I was careful that both pictures and narration appear simultaneously in my project. Swisher says that this too in turn aids in
creating connections and freeing up space in working memory. So I tried to ensure that all graphics were
meaningful and presented simultaneously with the narration. This was easy to accomplish as I was careful
to omit excessive text in addition to graphics.
