Distinguishes between Computer Extended Teaching (using computers as aids), Computer Assisted Teaching (using computers as an integral part of the instruction) and Computer Based Teaching (the computer-student dialogue is the major component of instruction). (AL)

A practical application of a physical law in the repair of a garage door. (CP)

Presents a series of mathematical models of natural events and isolated systems, equilibrium states, heat and volume-flow rules, energy-transformation rule, and the existence of equations of state. Lists 13 thermodynamic topics along with the mathematics prerequisites. Identifies the grade level in which these topics may be successfully taught.…

Presents the results of an analysis of Balmer's draft manuscripts, which revealed new and pertinent details about the genesis of the Balmer series. In particular the origin and nature of Balmer's geometrical construction for the series is described. In addition, it is shown that the Balmer series played a direct role in the formulation of the…

Presents a critical review of a book which claims to resolve the paradox of Einstein, Podolsky, and Rosen. ARgues that, although the book does exhibit a consistent quantum formalism for dealing with situations of the type involved in the original paradox, that formalism, so far from doing away with the paradox, serves only to highlight the…

Presents the premise that conditions on the job are much more significant to physics teachers than preservice education. Believes that a reorientation of the student to the teacher's role is the goal of preservice education. Situations should be presented so students experience the role of the teacher. (TS)
