One of the responsibilities of an instructional designer is to use cognitive science and instructional design principles to inform the creation of efficient and effective learning experiences that are suited to the learner and context. The content created should not impose unnecessary cognitive load (extraneous cognitive load) on the learners, rather content should be created so that relationships, concepts, and ideas are readily obtained by the learner.
I am developing an elearning module for a new product offered by a corporate client. In this project, as well as with paper-based instructional content I’ve created, I have found that a good graphic is worth a thousand words. For my current project, I used a 4 X 5 table to illustrate declarative knowledge that would take several paragraphs of text.
As an instructional designer, it is my job to create content that is displayed in a more efficient, less cognitively-taxing way than strictly text-based delivery; the way I do that is with graphics.
