Supporting Learning and Promoting Conceptual Change with Box and AVOW Diagrams. Part 1: Representational Design and Instructional Approaches.

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)
