Abstract:
Analyzes how two electromagnetism textbooks approach the concept of electric field. Uses historical evolution of the field representation. Indicates that one textbook mixes up the historical and pedagogical reasons for the introduction of the concept of field while the other one presents a sketch that might lead students to understand the field and the action-at-a-distance views as supplementing each other.

Abstract:
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)
