Cognitive Load
Cognitive Load Theory (John Sweller)
“Learning happens best under conditions that are aligned with human
cognitive architecture.” (http://www.instructionaldesign.org/theories/cognitive-load.html)
Learning requires use of working memory in order to form information
structures (schema).
Each decision a student must make in order to learn increases cognitive load.
Cognitive load should be kept to a minimum via instructional design.
Audio
The Modality Effect
Students learn better when audio accompanies visuals (Ginns, 2005)
“The modality effect refers to a cognitive load learning effect which occurs
when a mixed mode (partly visual and partly auditory) presentation of
information is more effective than when the same information is
presented in a single mode (either visual or auditory alone).”

Why Use Video?
We will present each section by giving you the Big Picture concept. You really need to work
to understand this first. Once you do you will begin to fill in the details by using your course
textbook. Let’s look at an example of the Big Picture approach. One important concept has
to do with the way the body is organized. A textbook or lecture might read something like
this: The body is organized into axial and appendicular portions. The axial portion contains
the head or cephalon, the neck or cervical region and the trunk consisting of the thorax,
abdomen and pelvis. The appendicular portion consists of the upper and lower extremities
including the shoulder and pelvic girdles. The axial portion of the body contains cavities.
These include the dorsal and ventral cavities. The dorsal cavity contains the cranial cavity
superiorly and spinal canal inferiorly while the ventral cavity contains the thoracic and
abdominopelvic cavities. The thoracic and abdominopelvic cavities are separated by the
diaphragm. The thoracic cavity lies superior and the abdominopelvic cavity lies inferior…
Using the the Big Picture approach we could say the following: The body consists of solid
parts and hollow parts. The solid parts are the arms and legs while the hollow parts are in
the head, back, chest and stomach. There is a big hollow part in the front and a smaller
hollow part in the back. Hey the organs have to go somewhere. The front of the body is
known as the ventral part and the back of the body is known as the dorsal part (think of a
dorsal fin on a shark). So the hollow part in the front is called the ventral cavity. The hollow
part in the back is called the dorsal cavity. The upper part of the ventral cavity is in the chest
and is called the thoracic cavity. The lower part of the ventral cavity is the stomach and
called the abdominopelvic cavity (think abdomen and pelvis). The two parts are separated
by the diaphragm. There’s gotta be a hollow part in your head to contain your brain and
that’s called the cranial cavity. There’s also a hollow part that contains the spinal cord called
the spinal canal.
Video
Advantages:
Access to content at any time
Support for face to face courses
Videos are a great way to support lectures and activities done in traditional face
to face classes
Ability to pause and replay video
Students can replay sections of videos, pause and take notes for learning more
difficult sections or for practice
Greater connection to instructor
You can use video in your course for:
Introducing yourself and your course
Presenting content
Providing feedback

Tips for Using Video
Avoid the Talking Head
Plan Your Video
Keep it Short (5-7 minutes)
Use Images But Kill Clip Art
Don’t Use a Lot of Text
Keep Narration Conversational
Kill Background Music and Sound Effects
Use a Clean Look
Use Cartoons/Avatars
