I was highly encouraged to delve into this study when I discovered the work of Lloyd Rieber. Working with learners of all ages from 5th grade through adult, Rieber compared static illustration of Newtonian Physics instruction with animated versions.
and
He wasnít the only one who had worked with animation. It has been a promising area of research for instruction in the fields of physics, math and science, where the principles instructed are those that involve motion or other change of physical or theoretical state.
†† One thing Animation studies have in common is that they all show some kind of quantitative differences due to the use of animation in instruction.
Some have asserted significant benefits affecting attitudes, enjoyment, motivation and frustration levels while others have tried to measure animationís effect upon immediate recall, retention, and problem-solving skills.

The second thing that animation studies have in common is that they are nearly all based on the theoretical work of Alan Paivio on Dual Coding Theory.Most of them are actually framed so that they set out to show support, with success, for the theory.
.. that memory operates through two separate, semantic representation systems, the verbal, and the non-verbal. Information is easier to retain in memory when it is dual coded, or represented in both subsystems - in pictures and in words.
