This study is focused on the concept and formalism of work done and potential energy on the very fundamental level. A detailed analysis of the incomplete presentations of the topics found a major misconception that precluded acknowledgement of existence of certain nonradial effects caused by classical radial/center-bound gravitational force fields…

Investigates student reasoning about models of conduction. Reports that students often are unable to account for the existence of free electrons in a conductor and create models that lead to incorrect predictions and responses contradictory to expert descriptions of the physics involved.

A program for teaching the concepts of electric energy, voltage, and current is proposed. The ideas and concepts are introduced in a sequence that places more emphasis on some aspects that are normally treated very briefly. A phenomenological orientation, qualitative and quantitative micro- and macroscopic treatments, and the inclusion of the…

This article is the first of a two-part review of research on children's and adults understanding of gravity and on how best to teach gravity concepts to students and teachers. This first article concerns free fall--how and why objects fall when they are dropped. The review begins with a brief historical sketch of how these ideas were developed in…

Fourteen elementary and middle school teachers from an inservice physics course were found to share a common core of strongly held propositions that formed a coherent, but incorrect and contradictory, model of the sequential flow of electrical current. Theoretical and practical implications of these teachers' beliefs with respect to both…

This is the second and final part of a review of educational research on children's ideas about gravity. The first part concerned students' understanding of how and why things fall. This article picks up the trail of research studies that address students' understanding of the more complex ideas of projectile motion and orbits and examines how the…
