Being constructive: An alternative approach to the teaching of introductory ideas in electricity

This paper reports on the development and implementation of an introductory course on electric circuits based on a constructivist model of curriculum development and teaching. Pupil interviews before instruction explored and clarified the range of children's existing ideas and conceptions. A teaching sequence was designed to elicit pupils’ ideas, to challenge these experimentally where they differed from accepted scientific ideas and to encourage discussion and reformulation of ideas. Post‐instruction interviews showed improved pupil understanding of several important basic concepts. The constructivist approach appeared to provide a viable and satisfactory basis for teachers’ classroom decision‐making and for the structuring and sequencing of activities as the course progressed.
