Presents some experiences of a physics teacher in inventing apparatus, obtaining patents, starting a company, and going into production. (GS)

Sets forth laboratory requirements for space, furniture, services, and special needs. Briefly reviews current laboratory conditions and practices and provides references for further research in this area. (GS)

Describes a simple and inexpensive model to demonstrate the pulsed magnetic resonance phenomenon. Gives the details of construction of the device which can provide a direct demonstration of the precessional motion of a magnetic moment in a steady magnetic field. (Author/GS)

Provides an outline of the topics covered in the program. Included are introductions to transactional analysis and Piaget's theory of intellectual development. Explains the evaluation of the program and presents data obtained from past participants. (GS)

Describes a competency-based instruction (CBI) system in which a student must regularly demonstrate satisfactory understanding or performance of specified competencies in order to proceed to new materials. Reports mastery and timing results suggesting more efficient learning in a CBI system. (Author/GS)

One dilemma of constructivist modes of instruction, which involve engaging students in discussions concerning a range of possible explanations for a given phenomenon, is that such an approach may confuse students who believe that absolute scientific truth exists. Historical dialogues in which various perspectives are aired by key scientists of the…

This module applies basic laws of thermodynamics to the study of the efficiency at which heat can be converted to other useful forms of energy, including heat at low temperatures. The module is divided into four major sections. Section I treats energy conversion efficiency and defines the concept of first-law efficiency, the most widely used…

Presented are demonstrations and experiments that can be used by a variety of high school physics classes. The 131 demonstrations and 27 experiments were selected since they illustrate physical concepts clearly and directly, are simple to perform, and require a minimum of expensive or specialized equipment. Each demonstration and experiment is…

Physics 30 is a twelfth-grade physics course for students in Alberta, Canada. This document is a final test for the course. Intended for administration during January 1986, it contains 56 multiple-choice questions and four written-response problems. Two-and-one-half hours are allowed for completing the test. No answer key is included since scoring…

Tribology is the science and technology of interacting surfaces in relative motion. It incorporates a number of scientific fields, including friction, wear, lubrication, materials science, and various branches of surface physics and surface chemistry. Tribology forms a vital part of engineering science. The interacting surfaces may be on machinery…

Analogical reasoning and learning applied to the task of constructing qualitative explanations for physical phenomena are the subjects of this investigation. Two issues are addressed. The first is how analogies are elaborated to sanction new inferences about a novel situation. This issue is adddressed by contextual structure-mapping, a…

This is a textbook of Fourier optics for the classroom or self-study. Major topics included in the 38 chapters are: Huygens' principle and Fourier transforms; image formation; optical coherence theory; coherent imaging; image analysis; coherent noise; interferometry; holography; communication theory techniques; analog optical computing; phase…

In the teaching of physics, the study of electricity and magnetism typically follows the introduction of the basic concepts of mechanics. However, there are some new concepts associated with electromagnetic fields that seem at first to the student to be unrelated to, or even incompatible with, Newton's third law as learned in mechanics.…
