Developing and using conceptual computer animations for chemistry instruction

Multimedia technology has advanced rapidly within the past two years providing an opportunity for chemistry instructors to develop and use their own computer animations. Conceptual computer animations are designed to help students understand the basic concept or principle of a dynamic chemical process. This paper discusses several issues surrounding the development and use of instructional conceptual computer animations. If possible, an animation sequence should be linked to a lecture demonstration, thereby assisting in the presentation of all three levels of representation: microscopic, macroscopic and symbolic. Computer animations provide instructors with a vehicle for presenting topics from the particulate nature of matter view and a technique for teaching for conceptual understanding. A design team consisting of individuals who have knowledge or expertise in the content area, instructional design, computer animation techniques, and graphic and sound production should work with the chemistry instructor...
