Attempts to briefly answer why computers should enter the educational scene, and how can they be effectively employed in this context. With emphasis on physics, several operating systems used in England and the United States are described. (TS)

Techniques which use the shadow of the earth as a reference in relation to the angular radii of the sun and moon permit determination of the distance from the earth to the moon. (TS)

The answers from test questions on circular motion are analyzed in terms of the misunderstandings of resultant force, kinematics, interaction, and centrifugal force. (DS)

Intended to guide college physicists to literature on nuclear and sub-nuclear particle detectors. The paper contains a discussion of (1) interactions of particles with matter and (2) individual particle detectors, each section being followed by an annotated bibliography of selected reference materials. Rankings are given to the articles on the…

Describes the structure of a set of computer programs (DITRAN) that translate the text of conversational exchanges appropriate for elementary physics discussions into an operational computer-based dialog. Dialogs produced in this manner are designed as a series of templated subprograms. The structure of a simple template is reviewed. (Author/TS)
