Described is the College Success Program designed to enhance retention of at-risk individuals. The goals, bioethics course offerings at various colleges, course outline for a bioethics course taught in the humanities, and evaluation of the course are discussed. (CW)

Presented is an activity that may be used to help students clarify the basics of graphing while allowing individuals to collect data and perform a simple experiment. A timetable, rules for graphing, materials, procedures, and suggestions for extension activities are provided. (CW)

Described is the evaluation of the Master of Environmental Science program at Monash University (Australia). The design of the evaluation is discussed, and the use of multiple sources of data and an innovative style are highlighted. (Author/CW)

Reorganization in the National Science Foundation's science education section is discussed. Personnel changes and changes in funding in 1990 are emphasized. (CW)

Described is a demonstration which involves the ingrowth of members of the radon-222 decay series. Laboratory procedures, equipment, analysis, and results are discussed. (CW)

Described is a simple and interesting chromatography experiment using three different fluorescence detection principles for the determination of caffeine, saccharin and sodium benzoate in beverages. Experimental procedures and an analysis and discussion of the results are included. (CW)

Results from the analysis of land and marine records from the past century are presented. It is indicated that the planet earth has warmed about one-half of a degree celsius. The uncertainty of these measurements and future warming trends are discussed. (CW)

Presented are the procedures and a discussion of the results for an experiment in which students select unknown carboxylic acids, determine their melting points, and investigate their solubility behavior in water and ethanol. A table of selected carboxylic acids is included. (CW)

Cited are the experiences of the authors with a college-level course which used science fiction films to teach scientific principles. Included is a set of sample scientific concepts explored using the film "Forbidden Planet." (CW)

Described are some of the considerations necessary in planning a field studies course in the tropics. Discussed are site selection; planning and preparation; course structure; the advantages of travel courses; and recommendations concerning liability, multiple instructors, hotels, sailboats, and tours. A list of 26 references is included. (CW)

Presented are arguments for the use of a case study approach for the teaching of human heredity. The design of case studies and related exercises is discussed. Five examples are given. A list of eight resources for case study samples is included. (CW)

Considered is an experiment used to investigate one-dimensional, nonuniform acceleration. Presented is the correct expression for the acceleration, generalized to include friction and describe simulations supporting student data. The feasibility of the experiment is questioned. (CW)

A model of the phenomenon of the desert mirage is presented using Snell's Law and simple programing techniques. Optical trajectories predicted by the model are illustrated. (CW)

Presented is a course that applies concepts from sociology, anthropology, linguistics, and social studies of science to the question of expert status. Included are major concepts to be covered, suggested readings and annotated bibliography, and possible class exercises. (KR)

Described is a project involving the introduction of microcomputers into the laboratory portion of a college general physics course for data collection and analysis. The results of an evaluation of this program are presented. (CW)
