Describes an experiment in which students are given a naturally occurring oligosaccharide as an unknown and are asked to determine both its monosaccharide composition and its structure. Discusses methods and experimental techniques including thin layer chromatography and the use of enzymes. (CW)

Described is a simple device, that uses a laser beam to simulate P waves. It allows students to follow ray paths, reflections and refractions within the earth. Included is a set of exercises that lead students through the steps by which the presence of the outer and inner cores can be recognized. (Author/CW)

Discusses ways that chemists have traditionally used models to represent chemical structures. Suggests new ways to construct three-dimensional models of receptor sites using thermoplastics or heavy aluminum foil. Provides sketches and photographs of several models. Points out the advantages of using such models over traditional two-dimensional…

Discusses the need for student research-type chemistry projects based upon "unknown" metal complexes. Describes an experiment involving the product from the reaction between cobalt(II) chloride, ethane-1,2-diamine (en) and concentrated hydrochloric acid. Outlines the preparation of the cobalt complex, along with procedure, results and…

Studies the interviews of 24 professional scientists to seek their views on the long range effects of their initial training. Analyzes the interviews for content, teaching, and types of learning experience. Concludes with a discussion of the implications of the findings for science education. Argues for a reduction in content. (CW)

Reports on the results of a University of Arizona experiment that used electronic mail to supplement traditional modes of student/instructor interaction in four courses in electrical and computer engineering. Results indicated that students liked electronic mail to supplement their discourse with their instructors. (TW)

Describes the interdisciplinary activities of the extension unit known as the Office of Environmental Programs at the University of Nebraska-Lincoln. Focuses on the coordination and training involved in programs dealing with pest management and water quality. (TW)

Describes a 15-week course in the fundamentals of microelectronics processing in chemical engineering, which emphasizes the use of very large scale integration (VLSI). Provides a listing of the topics covered in the course outline, along with a sample of some of the final projects done by students. (TW)

Discusses the need to integrate management and technology in engineering education programs. Describes the undergraduate management and technology program at the University of Pennsylvania. Outlines both the four-year and five-year options, describing two integrative courses that were developed specifically for the program. (TW)

Presents an overview of biochemical education in China, including a description of the overall Chinese educational system. Summarizes workshop sessions which dealt with teaching objectives, teaching methods, self-instruction, and the education of graduate students (including the use of "dry" laboratory exercises and research…

Discusses the need for compliance with state and federal regulations regarding the handling of hazardous wastes in college chemistry laboratories. Addresses: (1) waste determination; (2) facility requirements; (3) use of the manifest, vendor, transporter, site selection requirements, and training; (4) contingency planning; and (5) documentation.…

Describes nine chemistry demonstrations that can be done using an overhead projector. Includes demonstrations on common ion effect, crystal formation from supersaturated solutions, making iron positive with nitric acid, optical activity, carbon dioxide in human breath, amphoteric hydroxides, the surface tension of mercury, and natural acid-base…

Describes a computer-training needs assessment conducted in a manufacturing company which was performed by students in an industrial education course at the University of Minnesota. Provides suggestions for educators in providing computer training to the private sector. (TW)

Presents a new method to teach the subject of evaporators which is both simple enough to use in the classroom and accurate and flexible enough to be used as a design tool in practice. Gives an example using a triple evaporator series. Analyzes the effect of this method. (CW)

Summarizes the results of a preferred method of study questionnaire in which college students explained how they approached reading a new textbook. Reports that women showed a significant preference for adopting a single method of study. Indicates that there was no discernable relationship between study strategies and college level. (CW)
