Aligning affordances of graphics with learning task requirements

摘要

Dynamic subject matter can be portrayed to learners in the form of either static or dynamic depictions. Two plausible bases for choosing a depiction format are alignment with the subject matter's dynamics, or the specific affordances a depiction provides for performing a particular learning output task. Experimental participants viewed an ordered set of eight images depicting key stages of a kangaroo hop presented in a dynamic, successive or simultaneous format. Control participants viewed no presentation. The output task required participants to rearrange a random sequence of the eight kangaroo images into the correct order of a kangaroo hop. Those who viewed the successive presentation were most successful in placing the images in their correct order while those in the dynamic condition were least successful. The results contradict the prevailing instructional design orthodoxy that the dynamic properties of a depiction should be aligned with the dynamic nature of the referent content.
