The use of instructional
strategies is an effective way to manage learner cognitive overload. You
will have heard of most of these strategies mentioned below, perhaps even
used a few of them. This is not by any means a comprehensive list of instructional
strategies, but it is a good start.

Here are a few instructional
strategies that will effectively manage cogntive load:
Define Job-Essential
Knowledge and Skills
Leave out the nice-to-know information and focus the training on the need-to-know
information. There is usually not enough time to squeeze it all in, by
leaving out non-relevant information there will be more time for hands-on
activities.
Practice, practice,
practice
Frequent practice, and mere repetion, helps to transfer the information
from the working memory to the long-term memory. This will clear up the
working memory to process new information.
Reference-Based
Training
This type of training allows the learner to focus on the tasks and not
large amounts of materials. Reference-based training uses either a reference
manual or online Electronic Performance Support System (EPSS) and eliminates
the need for the learners to memorize large amounts of information prior
to learning the tasks specific to their job.
Provide Student
Notes
If the leanerns are provided with 80% or more of the content, less time
is spent on taking notes and more time can be spent on practice and hands-on
activities. Less lecture and more doing.
Chunk the Instruction
"Chunk" the content into 5-7 pieces, this is the amout of information
that the working memory can remember and process at the same time without
becoming overloaded. Keeping the lessons shorter will also help the learners
stay focused on the training, making sure to insert frequent practice
in the content as well.
Provide Job Aids
Job aids are helpful for the learner with remembering important tasks
and procedures. Job aids also cut down the amount of time spent on note
taking and ensure that the tasks or procedures are copied down correctly.
(Clark, 1997)

One of the most imortant strategies that you can use when designing online
instruction is the KIS principle, "Keep It Simple". The following
are some strategies that you can use for online instruction:
- Design consistent
user interfaces
- Design simple user
interfaces
- Use plenty of white
space
- Design easy to
use, consistent navigation
- Limit the amount
of material on the screen
- Provide electronic
job aids (i.e. help function or EPSS)
- Integrate graphics
and audio
(Clark, 1997)

The idea behind these
instructional strategies is to clear the working memory by transferring
the new informaiton to the long-term memory. Information is transferred
to the long-term memory by frequent practice and repetion, so it is important
to have as many hands-on activities as possible. Once the information
has been transferred to the long-term memory, the working memory is free
to process and learn more information.
Remember that cognitive
overload occurs in when the working memory cannot process information
at the speed or in the quantity at which it is being presented! Slow down
and and use smaller chunks of information!
