ABSTRACT
The Representational Redescription model suggested by Karmiloff-Smith describes a process through which children elaborate their knowledge from unconscious and implicit levels to conscious explicit levels. The model also assumes that children operating at explicit levels are able to express their own representation of knowledge verbally. This study was undertaken in order to identify the developmental levels of representational redescription in number conservation. This study examined the ability to conserve numbers amongst 234 children aged 5 to 6 years. The materials used were linear arrays of 2×2㎝black cardboard squares. One of the two arrays in a pair always contained 4, 8 or 20 squares. Each child was asked about the equality of the arrays. Of 234, 89 of the conservers could be classified into one of three levels (I, E1, E3) which were described by Karmiloff-Smith without E2. This result indicates that this study provides evidence for the existence of representational redescription in number conservation.
