1. âA theory that focuses the load on working
memory during instruction.â
John Sweller
The Cognitive Load Theory
SD, MC, SY, RS
2. Overview
ïJohn Swellerâs paper, âImplications of Cognitive
Load Theory for Multimedia Learningâ describes the
human cognitive architecture, and the need to apply
sound instructional design principles based on our
knowledge of the brain and memory. Sweller first
describes the different types of memory, and how
both are interrelated, because schemas held in long-
term memory, acting as a âcentral executiveâ,
directly affect the manner in which information is
synthesized in working memory. Sweller then explains
that in the absence of schemas, instructional
guidance must provide a substitute for learners to
develop either own schemas.

3. The TheoryâŠ
Sweller discusses, in his view, three types of cognitive load:

âą extraneous cognitive load
âą intrinsic cognitive load
âągermane cognitive load
4. Intrinsic Cognitive Load
ïFirst described by Chandler and
Sweller, intrinsic cognitive load is
the idea that all instruction has an
inherent difficulty associated with it
(for instance, calculating 5+5). This
inherent difficulty may not be altered
by an instructor. However many schemas
may be broken into individual
âsubschemasâ and taught in isolation,
to be later brought back together and
described as a combined whole.

5. Intrinsic Cognitive Load
ïŹIntrinsic load is the âthinkingâ part of
cognitive learning theory.
ïŹFor example, if one were learning the
mechanics of 2+2 for the first time, one
would have to think about the combination
of two items with another two items.
Essentially, one would have two items, then
another item (3) and then another item (4).
ïŹThe amount of âthinkingâ or âintrinsic
loadâ affects the learning capacity.
Another key component is the way in which
the material is presented.

6. Extraneous Cognitive Load
ïExtraneous cognitive load, by contrast, is under the control
of instructional designers. This form of cognitive load is
generated by the manner in which information is presented
to learners (i.e., the design). To illustrate an example of
extraneous cognitive load, assume there are at least two
possible ways to describe a geometric shape like a triangle.
An instructor could describe a triangle verbally, but to show
a diagram of a triangle is much better because the learner
does not have to deal with extraneous, unnecessary
information.

7. Extraneous Cognitive Load
Extraneous cognitive load is the âmaterialsâ part of cognitive learning theory.
Imagine that a teacher asks a student to turn to page 54 in her book, locate section
2.1 and solve problem 3. However, when the student turns to that page in the book,
it looks like the following:
This will present some unnecessary extraneous cognitive load.

8. Extraneous Cognitive Load
Due to lack of images on the previous page, the student will be bombarded with
extraneous cognitive load. However, the student would be under much less load
with a page similar to this:

9. Germane Cognitive Load
ïGermane load is a third kind of
cognitive load which is encouraged to
be promoted. Germane load is the load
dedicated to the processing,
construction and automation of schemas.
While intrinsic load is generally
thought to be immutable, instructional
designers can manipulate extraneous and
germane load. It is suggested that they
limit extraneous load and promote
germane load.

10. Germane Cognitive Load
âą Germane load is the load used in
forming new schemas.
âą Think back to our example of 2+2 for a
moment. As an adult, we do not have to
think about have two items, then adding
another, then adding another. We
already know that 2+2=4.
âą We use this knowledge to solve high
level problems. For example, one could
quickly tell me that 1,001,242 + 2 =
1,001,244
âą These rules do not change. These areSource :http://www.usask.ca/education/coursework/802papers/chipperfield/index.htm
12. Implications
ïWorking memory is extremely limited.
ïLong term memory is essentially
unlimited.
ïThe process of learning requires
working memory to be actively engaged
in the comprehension (and processing)
of instructional material to encode to-
be-learned information into long term
memory.
ïIf the resources of working memory are
exceeded then learning will be

13. Classroom Implications
ï The goal of the instructor should be to reduce extraneous
cognitive load and increase germane cognitive load.
Instructors can accomplish this in a variety of ways:
A. Change problem solving methods to avoid means-ends
approaches that impose a heavy working memory load by
using goal-free problems or worked examples.
B.Physically integrate multiple sources of information
whenever possible to eliminate the need for learners to
have to mentally integrate that information which
increases the load on working memory.
C.Reduce redundancy and repetitive information whenever
possible so that the load on working memory is lessened.
D.Use auditory and visual information under conditions where
both sources of information are essential (i.e. non-
redundant) to understanding. This helps increase the
capacity of working memory.

14. Additional Implications...
⊠Especially with
textbooks!
âą Because a textbook page is all text it
takes more time finding the first problem.
âą A students eyes have to refer back to the
example on the previous page, if thatâs
the case.
âą The student is feels worried because of
the time limit on the assignment. They
want to go out with their friends tonight
and do not want to have to do homework or
stay late after school.
âą The student wishes that the two students
in front of them would stop whispering and
they silently swear at the squeaky desk.11/23/10
15. Technological Application
ïThe Cognitive Load Theory can be implemented into
the technologically-enabled classroom in many ways.
PowerPoints are a great way to provide graphics and
text together, while computer activities can provide
worked examples and practice.

20. Technological Distraction
ïInstructors with access to technology may be tempted
to use it as much as possible in the classroom.
While technology can be helpful, due to the idea of
extraneous cognitive load it may also be a
distraction. For example, the Coherence Effect
states that peoplesâ learning is hindered when
extraneous sound, pictures, and words are used in
teaching. Therefore, instructors should avoid using
distracting pictures or sounds in PowerPoint
presentations. Also, the Modality Effect states
that people learn better when words are presented as
speech rather than onscreen text, so teachers should
not rely solely on technology such as a computer
screen or a PowerPoint to provide information.

21. âą This theory is best applied in the
area of instructional design and
complex material. With this a learner
should be encouraged to use their
limited working memory appropriately.
In order to use this affectively,
recognizing the role and the
limitation of working memory to help
develop quality instruction is key.
Although this theory has many
implications, if used correctly can be
effective. However, we must remember
to keep cognitive load of learners at
