Describes how to construct a traffic light device for use in teaching about wavelengths in physics. (LS)

Describes how to modify an electroscope so the charge can not leak out. (LS)

Describes a course, taught in Jamaica, for prospective high school physics teachers that stresses concepts which are difficult to teach and easily misunderstood by students. Also stresses preparing high school students to take national exams and teaching physics in poorly equipped laboratories. (MLH)

Describes the experimental apparatus and method for the study of magnetic vector potential (MVP). Includes a discussion of inherent errors in the calculations involved, precision of the results, and further applications of MVP. (GS)

Describes the application of the Keller Plan to an introductory physics course. Presents the organization of the course, faculty and student reaction to the course, and an assessment of the course on the basis of student grade distribution. (GS)

Considers cosmic rays and relationship to fields of geophysics and astrophysics. Reveals importance of solar eclipses in the study of cosmic radiation. (CP)

Recommends practices to be followed in the preparation of lecture demonstration video-tapes. (CP)

Describes the construction and use of the teacher developed nomograms as an aid in calculation for the less academic student, and in the teaching of mechanics, Boyles' law, and momentum. (GS)

Describes how you can lead students to erroneous inferences and conclusions by using demonstrations which point out to students the importance of carefully distinguishing between observations and inferences. (BR)

Illustrates a sample remedial program in mathematics for physics students. Describes two computer games with successful instructional strategies and programs which help mathematically unsophisticated students to grasp the notion of a differential equation. (GH)

Traces the history of astronomy by analyzing the scientific literature of various time periods, reviewing prize-winning research, and noting the input from physics. Speculates on some accomplishments that may occur in the next 75 years. (GS)

An analysis of data from three national testing programs shows that mean scores on physics tests are increasing, but the number of examinees is decreasing. (Author/GS)

Recent years have seen widespread adoption of automatic grading of physics homework problems. Although first-generation homework management systems provide feedback and assign scores based only on the answers, problem-solving performance on exams seems to be no worse for students using these systems than for those who receive detailed comments…

Physics First has gained momentum across the country. Providing a radically different paradigm to teaching science at the high school level, the Physics First movement inverts the traditional science sequence by teaching physics to ninth grade students. One of the benefits of this change, supporters claim, is that it provides a foundation to teach…
