What are the Earth and the heavenly bodies like? A study of objectual conceptions among Norwegian deaf and hearing pupils

Abstract

This study addresses deaf pupils' conceptions of phenomena, that can be directly observed, of the Earth and sky. In the study deaf pupils aged 7, 9, 11, and 17 years were interviewed. A control group of 9-year-old Norwegian pupils with normal hearing was also interviewed. The results show that the young deaf children have conceptions that are remarkably like the scientifically accepted ones, when their age is taken into account, while this is not the case for the oldest groups. Four out of five deaf 7-year-olds, for example, thought the Earth was spherical, not flat; while only five out of eight deaf 17-year-olds thought the same for shapes of the heavenly bodies. Possible reasons for this are discussed. The results also indicate that the shapes of the signs representing objects may affect deaf people's conceptions of those objects.
