What are Coherence Principles 2 and 3?
What are Coherence Principles 2 and 3?
Coherence Principle:
This principle indicates interesting yet unnecessary media such as words, pictures and sound added in order to make the media more appealing can be distracting and will frustrate the learner. An objective of the multimedia designer should be to avoid using any material that is not
specifically related to the goals of instruction. While it seems like a simple rule of thumb,
it is not always followed.
Coherence Principle #2: This principle focuses on designing a media
tool that uses only those pictures which are necessary.
There is always the temptation to add a little extra however according
to the research one should not add pictures to a site like seasoning, to attempt to enhance a
boring lesson. The research also supports that these additional images can interfere with the learning process.
Coherence Principle #3: This principle focuses on designing media
tools that don’t use extraneous words.
When selecting the appropriate text for a site, additional words that do
not pertain to the instructional goals can hinder a student’s
understanding. Students can become
frustrated and a transfer of knowledge will be delayed.
DEMONSTRATING THE COHERENCE PRINCIPAL (or not)

Now I am
not one to shy away from color but this power point mage from a lesson on metaphors and similes goes a little overboard. The light green and white
background along with the letters is an excessive presentation in
color, shapes and patterns. This is also demonstrated in the next slide.
The text displayed in the lower half of the image above uses a combination of black
and white. This makes it very difficult
for the student to read the information and requires additional attention upon an
area that should not be the focus.
