Fundamentals of major electronic equipments on board ships are presented in this text prepared for naval officers in general. Basic radio principles are discussed in connection with various types of transmitters, receivers, antennas, couplers, transfer panels, remote-control units, frequency standard equipments, teletypewriters, and facsimile…

This report contains the papers presented in the 1970-1971 Environmental and Ecological Forum series, planned to provide an overview of the significant environmental, social, and economic aspects of electric power generation, more specifically, the pros and cons of nuclear power production. The Forum was organized as a public service to foster…

This paper gives a technical description of various computer graphics programs developed on the Sigma 7 computer. Terminals used are the Adage 100 and the Tektronix 4002-4010. Commands are Metasymbol procedures which access Metasymbol library subroutines; programs can also be coupled with FORTRAN programs. Available, inexpensive graphic terminals…

This UNESCO source book on teaching physics in schools provides a synthesis of views and policies prevalent throughout the world with respect to physics education. The book's contents are contributed by educators from several nations who have been able to give an international outlook in the discussion of various aspects of physics education. The…

THE SYSTEMATIC USE OF MOTIVATING MATERIALS WAS DEVELOPED AND EVALUATED THROUGH THE TECHNICAL DEVELOPMENT OF A VIDEO-SOUND SYSTEM FOR PROVIDING PROGRAMED TELEVISION TO INDIVIDUAL STUDENTS. FIVE PHYSICS PROGRAMS WERE DEVELOPED AND RECORDED ON VIDEOTAPE. EACH OF THE FIVE PROGRAMS HAD SEQUENCES PRECEDING IT WHICH WERE DESIGNED TO MOTIVATE THE STUDENT…

Investigated was the compatibility between the intellectual abilities of students and the level of intellectual operations required by secondary level physics textbooks. Student intellectual levels were determined for 949 tenth-, eleventh-, and twelfth-grade students by administration of Piagetian tasks. Major concepts presented in physics…

Describes a cooperative research and construction project suitable for undergraduate physics students. Steps involved in the development of a device to demonstrate the distribution of molecular velocities in gases are detailed. (CP)

Reports on the Undergraduate Research Opportunities Program (UROP) in the Massachusetts Institute of Technology (MIT) physics department. Surveys the philosophy and objectives of the program, its organization, rules, funding, growth, atmosphere, problems, and accomplishments. (Author/CP)

The pedagogy and an extensive listing of topics suitable for large scale demonstrations are provided. (CP)

Provides a method by which students with different levels of ability may be taught on individual basis by one instructor. A pretest, skill session, and retest format are described. An appendix lists programmed materials in basic and advanced skills which are available. (CP)

Provides an account of the way in which one small university has coped with limited funds and a small staff to provide laboratory activities for freshman physics courses. (CP)

Provides the outline of an introductory college-level physics course which combines astronomy, astrophysics, relativity and communications with a study of civilizations and the conditions necessary for life. Student comments and an informal evaluation of the course are included. (CP)

This article examines: (1) some difficulties associated with teacher interaction analyses, (2) well known teacher interaction scales, (3) current directions in research and practice in observation, and (4) special applications of teaching interaction analyses to the field of physics. (CP)

Presents Unit Nine Change and Chance of the Nuffield Advanced Physics, dealing with energy conservation, and a novel statistical approach to diffusion, thermal equilibrium and thermodynamics. Information about energy resources, alternative sources of energy, and energy-cost of materials are also presented. (HM)

Presents a classroom demonstration that illustrates the Law of Conservation of Energy. The demonstration utilizes a coupled pendulum device that can easily be constructed from ordinary monofilament fishing line and two metal pendulum bobs. (HM)
