Provides physics teachers with comments on the value and role of demonstrations during lecture sessions. (SK)

Describes the origin, development, and implementation of a cooperative education program at Thomas Moore College. Includes potential benefits for faculty participation in the program. (SK)

Describes the structure and content of a four-year physics/microcomputer degree program at the University of Surrey. (SK)

Presents three methods for removing silver nitrate stains, using (1) aqueous potassium iodide; (2) potassium ferricyanide in water; or (3) copper sulfate or chloride in water. (CS)

Focusing on history of physics, which began about 600 B.C. with the Ionian Greeks and reaching full development within three centuries, suggests that the creation of the concept of the atom is understandable within the context of Greek physical theory; so is the rejection of the atomic theory by the Greek physicists. (Author/SK)

Since many texts use an incorrect argument in obtaining the instantaneous velocity of a rotating body, a correct and concise derivation of this quantity for a rather general case is given. (Author/SK)

Discusses the meaning of symmetry of the laws of physics and symmetry of the universe and the connection between symmetries and asymmetries of the laws of physics and those of the universe. An explanation of Hamilton's principle is offered. The material is suitable for informal discussions with students. (Author/SK)

Electronic energy levels in noble gas atoms may be determined with a simple teaching apparatus incorporating a resonance potentials tube in which the electron beam intensity is held constant. The resulting spectra are little inferior to those obtained by more elaborate electron-impact methods and complement optical emission spectra. (Author/SK)

Details an introductory course in remote sensing for regional planners or non-science majors. Participants learn about remote sensing and how it can be used in geological areas. (MA)

Describes a conference that was organized to identify and bring out into the open, special problems facing master's institutions. The discussion at the conference centered around four interrelated issues: declining enrollments; employment opportunities, program design, and recruitment and finding. (GA)

Describes the implementation and impact of a two-semester mastery-oriented astrophysics sequence for upper-level physics/astrophysics majors designed to handle flexibly a wide range of student backgrounds. A Personalized System of Instruction (PSI) format was used fostering frequent student-instructor interaction and role-modeling behavior in…

Presents data indicating that a large number of multiple-choice problems gives a reasonable correlation with hand-graded problems. (SK)

Reports results of a study investigating the ability of college students to solve problems using proportional reasoning. Also discusses implications for consideration of Piagetian cognitive level of students in planning college courses. (CS)

Suggests a method for students to engage in research projects and orally present results in class. The basic idea is to have students work on individual projects around a central theme. Describes 20 projects centered around the halogenation of ketones. (Author/JN)

Examines reasons for including microprocessors in school curricula. Indicates that practical work with microprocessors is not easy and discusses problems associated with using and constructing these control and processing devices of microcomputers. (SK)
