Stopping to think about different types
of graphics is something I have not done before. However, in a
previous career as an instructional designer, we had many discussions
about the use of graphics and the value they can provide to
instructional materials. The third chapter in Norton and
Sprague's Technology for Teaching (2001)
would have been very useful for these discussions. This chapter
includes a section on the five kinds of images and their
purposes. An easy way to remember them is the acronoym
DROET. DROET stands for decorative, representational,
organizational, explanative, and transformational. For our
purposes in instructional design, one of our client's goal was to use
graphics strictly for explanative purposes--to explain a concept, label
an image, or show connections. To the client, graphics meant
colors and cost to instructional materials. They stressed using
images that only added value to the content. With a better
understanding of the types of images, it is easier to match the purpose
of the content to the purpose of the graphic.
In class we completed a document that used components of visual
language to summarize the main points of the purposes and used of
graphics in the classroom.
