Discusses whether electronics should be included as a subject at school, and describes the process of developing an O-level electronics course which is based on electronic systems for British schools. The course content and structure are also included. (HM)

Traces the history of the search for the ultimate nature of matter. The work of outstanding physicists since the late nineteenth century is discussed as it relates to the total picture of the search for a single unifying theory. (SA)

This resource letter is an annotated bibliography aimed at individuals who have recently become interested in lecture demonstrations in physics. Listed are 103 printed sources of information on lecture demonstrations. Whenever possible, annotations are followed by reviews so that other opinions can be consulted. (BT)

Describes how to measure Brewster's angle using Polaroid sunglasses and the reflection of the ceiling light on a polished floor. (GA)

Discusses electric field strength, magnetic field intensity, and magnetic induction showing the differences between the physical quantities involved and their units. (GA)

Discusses Barkla's part in the controversy around the J-phenomenon, and the different factors that contributed to the refutation of the phenomenon. (GA)

Describes an individualized Physical Science Study Committee (PSSC) physics program which follows the Personalized System of Instruction (PSI) format. The program has a variable-credit option, to provide flexibility to meet students' needs and interest. (GA)

Presents short articles on: display of line spectra, calorimeters, filling balloons from gas jets, and digital mini-module systems. (MLH)

Describes the summer program for minority students conducted at the Fermi National Accelerator Laboratory. (SL)

Presents an historical analysis of the work concept with particular emphasis given to the contributions of John Smeaton and Daniel Bernoulli. Emphasizes the work done by both applied and resisting forces. Contains 23 references. (DDR)

This research examines high school students' performance on an interactive multimedia tutorial for learning physics concepts in conjunction with their individual differences. Performance was compared between the initial portion of the tutorial where students learned concepts and the final portion where they applied the concepts. (Author/LRW)

Argues that although differential equations are billed as applied mathematics, there is rarely any hands-on experience incorporated into the course. Presents a laboratory project that requires students to obtain data from a physics lab and use that data to compute the coefficients of the second order differential equation, which mathematically…

Explains an approach to teaching dimensional analysis that differs slightly from the traditional approach. The difference lies in the novelty of exposition in the presentation and interpretation of dimensional analysis as a speculative process. (DDR)

Presents strategies for encouraging dialog with students from eliciting preconceptions to bringing closure to a unit. Includes the general structure of an instructional unit that employs dialog, strategies for teachers to use, and strategies for students which include active listening. (DDR)

Examines ways that teachers' knowledge about teaching and their educational situations grow when they are engaged collaboratively with other teachers in inquiry on their own practice. Results indicate that mechanisms for enhancement of normal practice include anecdote telling, trying out ideas, and systematic inquiry. Contains 66 references.…
