Presents information in brief on changing priorities in science education. Cites three categories of aims for science, traits of underachievers, and the processes of science. Includes reflections on the Salter's GCSE Scheme of Assessment, the integration of science and drama, and a historical perspective of practical work in school science. (RT)

Discusses the need for determining a curriculum to provide qualified hazardous waste personnel. Describes the needed role of colleges and universities and current hazardous materials certification requirements. Lists requirements for 18 professional certifications. (MVL)

Discusses the least squares technique and states the difficulty in finding suitable examples for using it in the chemical laboratory. Provides several least squares equations and the accompanying three dimensional drawings. Notes graphic lecture aids are available from the author as either slides or overheads. (MVL)

Provides a first experiment for college chemistry that provides insights into scientific procedures without presupposing any detailed knowledge of chemistry on the part of the student. Requires the student to measure successive masses and volumes and use these values to determine the density from the slope of the graph. (MVL)

Describes a laboratory experiment using AMPAC (a computer program) in conjunction with infrared spectroscopy. The experimental procedure and a list of questions for discussion are provided. Typical data are presented. (YP)

Discussed are the results of a teacher training workshop on problem solving and classroom demonstrations. The materials and topics used in the workshop are listed. Suggestions for using problem solving and classroom demonstrations are provided. (CW)

Discussed are the background, objectives, statement of need, target population, program activity, budget, staffing, funding, problems, and evaluation of the project. Suggestions for the initiation of analogous programs are provided. (CW)

Discusses the composition and properties of various types of coal. Follows the origin of coal and amounts available in the ground. Explores the anaerobic decay needed to produce coal. Touches upon the greenhouse effect. (MVL)

Discusses changes made since the publication of "A Nation at Risk." Presents a chemistry course in which scientific literacy is a major emphasis. Provides methodology for the course and a listing of the topics for instruction. Notes several criticisms of the approach. (MVL)

Discusses a survey of selected undergraduate chemistry laboratory courses. Topics include: who preps the experiment; degree of faculty involvement; instructional loads; types of directions used; satisfaction with materials used; techniques taught; computer use; rating the laboratory; and a self rating. Provides data for each topic. (MVL)

Notes that women have earned 20 percent of chemistry Ph.D. degrees in recent years but hold only 4.9 percent of tenure track faculty positions in graduate chemistry departments. Lists faculties with three or more women and with none. Reviews a survey by the American Chemical Society's Women Chemists Committee. (MVL)

Discusses a continuing education course that reached 1000 viewers at 43 North American sites. Points out that each professor had 35 minutes for his presentation followed by a 10-minute call-in question and answer period. Notes polymer topics will be the focus of upcoming lessons. (MVL)

Described is a plan used in Iowa to remove stockpiled, unwanted chemicals from storeroom shelves. Points out that the plan takes 12-15 months to complete. Notes the average cost per district was $575. (MVL)

Described is an experiment in which the student can ascertain the meaning of a negative result from a qualitative test by performing a more sensitive quantitative test on the same sample. Methodology for testing urinary glucose with a spectrophotometer at 630 nm and with commercial assaying glucose strips is presented. (MVL)
