Reports on the evaluation of a computer-based learning system at the University of Dundee (Scotland) used for computing courses. Describes use of the World Wide Web, tutorials, interface, motivation, perceived value in relation to lectures and laboratories, student attitudes, improvements made as a result of the evaluation, and future work. (LRW)

Discusses methods used to date archaeological artifacts and other remains. They include: (1) nuclear dating techniques (radiocarbon dating, accelerator radiocarbon dating, thermoluminescence, and others); (2) chemical dating techniques (amino acid racemization, obsidian hydration dating, elemental content changes, and thermal analysis dating); and (3) archaeomagnetism measurements. (JN)

Gives historical background on the discovery of natural radiation and discusses various techniques for using knowledge of radiochemistry in geochronological studies. Indicates that of these radioactive techniques, Potassium-40/Argon-40 dating is used most often. (JN)

Addresses the development of innovative skills in future engineers and the factors that promote and inhibit change. Describes two theoretical perspectives which deal with some of the factors affecting individuals and groups when confronted with the possibility of radical change. (TW)

Describes an inexpensive means for determining proximate analysis of coal, and by use of this data, its energy content. Pyrite content is also obtained by utilizing magnetic properties of iron. The simple device used makes the experiment suitable for the undergraduate laboratory. (Author/JN)

An inexpensive apparatus for demonstrating low temperature mineral synthesis in an undergraduate geology laboratory is described. (Author/SA)

Describes a simple, inexpensive Faraday balance for studying the effect of a strong magnetic field on selected reaction rates. Aschematic diagram detailing the essential features is included. (BT)
