Reflecting
on Instructional Videos
This
semester has taken us on a journey through the complex set of principles that have
been outlined by Swisher. As we have moved from using still images to represent
our thoughts and ideas to animations, and finally to videos, the difficulty
level has increased in regards to applying Swisher’s theories. Video differs
from using still images or digital storytelling in several different ways. The
first idea taken from the temporal contiguity principle discusses how students
learn better when corresponding words and pictures are presented simultaneously
rather than successively. In order to achieve this goal in digital storytelling,
the images on the screen needed to be directly correlated to the animation that
was being spoken. With the ability to overlay your voice on top of the images,
this was achieved quite easily. In the creation of the instructional video, it
was much more difficult to be constantly showing a demonstration while providing
narration at the same time. The use of still images along with the video and
narration would have made it easier to fulfill the requirements of this principle;
however it would not have properly addressed the parameters of the assignment.
The
modality principle also plays a role in the difference between still images and
video use. In this circumstance, both processing channels, visual and auditory
are being utilized to present information. The research supports the mixed use
of both channels as opposed to just one. The difference lies in that students retained
more information when given a narration and an animation, but in this instance
we are actually using video instead of animation. Ideally, creating a situation
where students could actually do hands on practice with whatever it is that you
are teaching would be the best practice.
Another principle
that I see that applies across the projects is the split-attention principle.
Integrating both the explanation and the demonstration together in one source
effectively increases learning. In this video, I tried to give an explanation
of how a wind generator works, and then followed by an additional explanation
with the demonstration. (I ended up editing out the first slide in my final
video due to size restrictions) It is very difficult to truly adhere to this
principle in the strictest sense. This brings me to my next topic of
discussion. When searching the internet for a variety of instructional videos, I
noticed that the videos that followed any of Swisher’s principles are few and
far between. In fact, it seemed like most of the videos I searched for went directly
against Swisher’s rationale. Specifically, I saw a lot of the redundancy
principle in various videos where the text on the screen was being read by the
narrator. In addition, I saw a lot of videos that went against the temporal contiguity
principle in the sense that words were presented on one slide and then pictures
representing the words were on the next slide. Overall, I have found that as
our project difficulty increases, so does the ability to properly follow Swisher’s
theories. My conclusion is that it is much easier to just create something that
looks nice and is fun, than it is to create something that adheres to the
multimedia principles.
