Fifth Class Session
In this session, Dr Yeap spoke about Dienes's theory on perceptual variability principle.
Perceptual Variability or Multiple Embodiment Principle: In order to allow as much scope as possible for individual variations in concept-formation and to induce children to gather the mathematical essence of an abstraction, the same conceptual structure should be presented in the form of as many perceptual equivalents as possible.
(Adapted from Dienes, Z.P, 1971 Building up Mathematics,4th ed.)
Also, for younger children, it is better to provide them with proportionate materials to manipulate with rather than non-proportionate materials. In addition, the materials must be natural, for instance when we teach children counting, we use eggs, then later move on to unnatural materials such as teddy bear counters.
