Presents the procedures involved in conducting a photochemical experiment intended to provide undergraduates with exposure to the synthetic advantages of organic photochemistry. (Author/SA)

A three-point linkage system in tomatoes is used to explain concepts of gene mapping, linking and statistical analysis. The system is designed for teaching the effective use of statistics, and the power of genetic analysis from statistical analysis of phenotypic ratios. (Author/SA)

Describes the process dynamics and control program developed by the chemical engineering department at the University of California, Santa Barbara. Undergraduate and graduate control courses and real-time computing courses are included. (HM)

Tests the immediate and delayed effectiveness of an instructional module, "Levels of Questioning," designed to improve the level of preservice science teachers' questions. Results indicate that the module was effective in raising the average question level but that skills were not retained. Recommendations are made for revision of the module. (CS)

Discusses how the British Post Office is using the Prestel information retrieval system. The information structure adopted for the Prestel databases and how the Prestel system hardware works are presented. Computer system software, types of information, and the impact of Prestel system on society are also presented. (HM)

Discusses three research topics which are concerned with eminently practical problems and deal at the same time with fundamental fluid dynamical problems. These research topics come from the general areas of chemical and biological engineering, geophysics, and pure mathematics. (HM)

Explains that education and research, after having been neglected during the Cultural Revolution in China, are once again receiving emphasis, aided by extensive reading and by the reprinting of Western scientific literature. (Author/GA)

Describes a technique for the laboratory culture of Eucyclops agilis using Euglena. Details of the life cycle are given, and suggestions for its use in laboratory practicals, and in investigations with sixth-form (16 to 18 year-olds) and college students in the United Kingdom. (Author/HM)

Presents the Award Address for the 1979 American Chemical Society Award in Chemical Education. Discusses teachers and learning situations which made a difference in the recipients' schooling and the significant attributes of teachers and techniques of teaching that stand out as lessons for would-be teachers. (BT)

Describes a programed, independent study, college level, general chemistry course designed to develop good technical laboratory skills with no attempt made to relate laboratory experiments and classroom topics. A list of experiments used and a sample laboratory examination are included. (BT)

Described is a base-friction modeling technique for studying the development of collapse structures in jointed rocks. A moving belt beneath weak material is designed to simulate gravity. A description is given of the model frame construction. (Author/SA)

Discusses various aspects of in-service training and the design of self-instruction material. Special reference is given to materials for application in various places but developed at a central location. Results are given of the use of experimental materials in medical laboratories in The Gambia. (Author/SA)

Suggestions are given for dealing with "senioritis" in high school students. These include offering college-level courses at a reduced cost. A description of introducing the college freshman biology course at Syracuse University into a high school program is given, with guidelines to promote success. (Author/SA)

An experiment for senior college undergraduate physics students is described. Amorphous tungsten trioxide films are suggested for use since they have a unique electrochromic system. (Author/SA)

Described is a graduate course in the process control curriculum at the University of Wisconsin that integrates real-time computing into process control teaching. Lecture topics and recent graduate laboratory projects are presented. (BT)
