Describes the six types of testing used in the Nuffield A-Level physics exam in Great Britain. Includes numerous item examples and discusses changes that have been made in the exam. (MLH)

Describes the 0-level Nuffield physics exam used in Great Britain and procedures for administering this exam. (MLH)

Discusses: (1) the fluid mosaic membrane structure and light reactions of photosynthesis as exemplified by the Hill and Bendall "Z-scheme"; (2) the arrangement of light-harvesting pigments, electron transport components, and ATP synthesis on chloroplast membranes; and (3) how these topics are treated in A-level textbooks. (JN)

Describes recent changes in the A-level physics syllabus of the University of London. Discusses the new emphasis on understanding and applying rather than pure role learning, and the changes in testing procedures caused by this emphasis. (MLH)

Discusses the present hierarchy of chemical education levels in Great Britain and proposed changes to this structure. (MLH)

Briefly discusses the nature of Colleges of Further Education in Britain and the role of science in their curricula. (JR)

Discusses changes that have taken place during the period 1951-1976 in the physics syllabuses and tests formulated by the Joint Matriculation Board for 0-level and A-level physics in Great Britain. (MLH)

This issue is divided into three sections: (1) Activities in Britain; (2) Overseas and International Activities; and (3) News. Numerous topics of interest to secondary school science and mathematics education pertaining to British education are presented. Included are reports on meetings, college programs, educational research, and educational…

Describes an activity (suitable for high school or college) in which the effects of competition in the structuring of ecological communities are examined. The exercise also offers an introduction into species diversity; more advanced classes may be encouraged to seek reasons for differences in insect diversity on different trees. (Author/JN)

An elementary physical model of cone receptor cells is explained and applied to complexities of human color vision. One-, two-, and three-receptor systems are considered, with the later shown to be the best model for the human eye. Color blindness is also discussed. (DH)

Describes (1) use of VELA (a stand-alone programmable instrument); (2) forced harmonic motion of galvanometers; (3) holographic interferometry and measurement of small angular displacement; and (4) an analogy useful on teaching capacitors at A-level. Also describes a comparison of fuses and circuit breakers using a microcomputer as a storage…

Provided is a microcomputer program listing which demonstrates the effects of selection on gene frequencies. A very brief description of the program is also provided. (JN)

Provides a general description of a preprogramed, microprocessor-based laboratory instrument, discussing its use in monitoring: (1) environmental changes; (2) distribution of count rates from a radioactive source, and (3) motion on an air tract. Includes list of the instrument's various capabilities: frequency meter, voltmeter, interval timer, and…

Compared performance in A-level science examinations of students who took an integrated science course (SCISP) with students who studied the separate subjects of physics, chemistry, and biology to 0-level standard. Results show no significant differences between the performance of the two groups. (JN)

The shore crab (Carcinus maenas) is an excellent subject for school study, both in the field and the laboratory. It is easily collected and maintained and can be used for a wide range of investigations. Some background details are given and possible areas of investigation suggested. (Author)
