Presents results of preliminary trials that suggest that the program devised helped UK Year 12 (A-level) learners develop useful concepts of current and voltage, acquire a more integrated understanding of circuit behavior, and overcome their tendencies towards localized and sequential reasoning. Provides learners with a valuable aid for problem solving. (Author/KHR)

Describes an approach to the teaching of electricity that uses box and AVOW diagrams, novel representations of the properties of the electric circuit that portray current, voltage, resistance, and power. The diagrams were developed as aids in learning, understanding, and problem solving and to promote conceptual change by challenging a number of commonly held misconceptions. (Author/KHR)
