Instructional animations: The in-house production of biology software

STUDENTS OFTEN have trouble conceptualizing certain phenomena in science. Traditional instructional media such as static illustrations, text, or video can be supplemented with computer animations in order to illuminate the concept for the learner. Some concepts must, by necessity, be depicted in this way in order to show processes or abstractions. The growing power of microcomputers and more user-friendly animation software have made in-house production of such animations a reality for the Iowa State University Biology program. Thirty scientific animations have been produced to date. This article explains how animations are developed from the conceptual drawing board to actual use in lecture halls and computer labs. Recommendations for the design, creation, and implementation of animations are outlined. Production is guided by practical technical considerations as well as instructional theory.
