Described is a demonstration in which the reaction sequence can be easily followed since the reactant, intermediates, and the final product have intense and different colors. Materials and procedures for this demonstration are discussed. (CW)

Described is the sequence of topics, learning activities, materials and demonstrations for the course. It is stressed that students can learn these skills in less than 30 hours of instruction. (CW)

Discussed are the motivations of geology teachers, a definition of teaching, and the meaning of geology. Stresses that teaching is a matter of providing opportunities for learning. (CW)

A method of plotting planes on stereonets is described including great circles, poles, and dip vectors. Teaching applications of dip vectors in engineering geology and structural geology are discussed. (CW)

Three uses of this method with sandstone, desert varnish, and granite weathering are described. Background information on this technique is provided. Advantages of this type of microscopy are stressed. (CW)

With time, an increasing number in the world population is becoming old, and changes in the aging brain mean that a significant proportion of the aged are likely to be dependent on others. The devotion of resources to research into the aging brain could bring benefits far outweighing the investment. (Author/CW)

Examines Canadian undergraduate science students' views of the nature of the relationship between science, technology, and society. Reports that the science students' views are similar to those of high school graduates, and that scientific facts are the central concern when dealing with the nature of science. (Author/YP)

Discusses the importance of student questions as tools of instruction and as indicators of student misconceptions. Suggests different ways in which students may gain an understanding of biological concepts through discussion of popular movies and biological problems. (CW)

Describes a fieldwork project in archaeology for teachers. Discusses one teacher's involvement in the Nevada program including field techniques and the development of a classroom lesson. Gives an address for obtaining information about the program. (CW)

Presents experiments which show that in electrostatics there are logical reasons for describing charged materials as positive or negative. Indicates that static and current electricity are not separate areas of physics. Diagrams of experiments and circuits are included. (RT)

Discusses the standards by which professors are evaluated for advancement and the reasons why these standards are antithetical to fostering a good learning environment for students. Gives some insights into what can be done to create an atmosphere in which teaching is not the lowest priority. (RT)

Discusses an organic laboratory program emphasizing individual experiments for the second semester of a two-semester course. Describes the outlines of two topics, including halide or alcohol synthesis and multistep synthesis. Provides reaction tables of alcohols and halides. (YP)

Presents data for instructors on the current state of ultraviolet-visible detector technology and gives sources of further information. Described are the mechanisms and characteristics of photomultiplier tubes and array detectors. Lists 15 references. (YP)

Examined are the illustrations and descriptions of the molecular structure of sulfur dioxide found in selected chemistry textbooks. Inconsistencies and incorrect information are indicated. It is suggested that molecules other than sulfur dioxide be used as examples of molecules for which resonance is important. (CW)

The construction and uses of a device to facilitate the use of an overhead projector to show chemical reactions is presented. Materials and instructions for construction as well as reactor vessels are discussed. (CW)
