Discusses a random self-paced examination which is designed to increase the number of high scores by making explicit the problems to be solved. Indicates that the novel examination is a useful part of the performance-grading method, rather than the competitive-grading method. (CC)

Discusses the technique of producing a grating with a spacing of 1 micron and 5 slits 50 microns long and 0.3 micron wide. Indicates that the slits are suitable for use in examination of electron diffraction patterns in the Gedanken experiment. (CC)

Discusses the procedures of conducting skill sessions in the teaching of physics to undergraduates. Indicates that the interim method can help students in acquiring necessary skills to solve problems but needs further improvement to become more useful. (CC)

Following the supposition that study of a subject through a specific problem is an effective way to develop thinking, the author advocates classroom experimentation that requires the student to put forth a hypothesis, test its validity, advance a theory, and try a new problem. (JH)

Describes a project aimed at producing an efficient piece of secondary science instructional material in accordance with current educational theory. Students involved in the study attained a satisfactory level of competence with material drawn from a much higher grade level, and in a shorter time span than is usually allowed. (JR)

Reports the results of a study relating to the most appropriate secondary grade level to enroll in physics, the reliability of standardized achievement scores in algebra and physics as predictors of success in high school physics, and the similarities in background and achievement of college and secondary physics students. (JR)

Describes several demonstrations designed to dispel student misconceptions relating to falling bodies. An object moving with a horizontal velocity is shown to fall to the earth as quickly as a free falling object dropped from the same height. (JR)

Describes the use of contract teaching with a class of competent senior students taking PSSC Physics. Explains the method used, reports the results obtained on tests in comparision with another class, and offers recommendations for teachers interested in trying this method.(JR)

Students' evaluations of instructors are indicators of good or bad instruction, but often fail to accurately identify the characteristics of the instruction. An observational system is described which yields relevant information concerning the nature of the instruction. (JP)

Discusses the nature and structure of an interdisciplinary course with emphasis on the problem of how the nervous system receives, processes, and transmits information. Included is a description of the course teaching to junior and senior physics and biology majors. (CC)

Describes the offering of a physics course where a mixture of teaching techniques and a wide variety of phenomena associated with light are used to attract students majoring in art, art history, psychology, photography etc. Indicates that the course is characterized by its in-depth and non-mathematical nature.
