Abstract
This paper begins by making a case for using personal construct psychology as a basis for a practical, constructivist approach to the learning of science. This is followed by the derivation of the approach through the generation of seven propositions from the psychology. The practical approach capable of implementation in a science classroom is then described and the links between the practical approach and the psychology are made clear so that the approach can be seen to be grounded in the psychology. The paper concludes with a summary of the results of the classroom implementation of the approach.
