Conceptualizing:
Sharing Ideas About Using Graphics

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.
