The Effects of an Age‐appropriate Intervention on Young Children's Understanding of Inheritance

Abstract

ABSTRACT The present study explored 4(N = 22) and 7‐year‐olds’ (N = 24) under‐Standing of biological inheritance in cows and horses. An intervention technique adapted from Springer (1995) in which children are taught the basic facts of intrauterine development and birth, in story form, was used in an attempt to improve children's conceptual understanding of inheritance. All children were pre‐tested about inheritance and subsequently half were trained using the intervention (the others were controls). All children were post‐tested within a week of pre‐test, and about 4 weeks later completed delayed post‐tests. Results showed that at pre‐test there were significant age differences in both judgements and explanations of inheritance with 7‐year‐olds exhibiting more sophisticated biological reasoning. Surprisingly, there were no significant improvements for either age in judgements or explanations of inheritance as a function of the intervention at post‐test or delayed post‐test. The findings are discussed with reference to theoretical issues surrounding children's theory of inheritance and the implications for training studies.
