Discusses the chemistry of the stratosphere at mid-latitudes, the Antarctic phenomenon, and temporal trends in ozone levels. Includes equations, diagrams of the global distribution of ozone, and halogen growth projections. Concludes that studies of stratospheric ozone demonstrate that the global environment is fragile and is impacted by human…

Describes a program to provide a major improvement in the national instrumental analysis capability of Chinese universities and associated industries. Notes the network ended its first five years of operation with a sense of accomplishment, but found its perspective much different than at the startup. (MVL)

Based on the results of an assessment of 241 teaching-learning programs in biology, chemistry, physics, general science (primary level), and informatics, this article discusses possible criteria for the assessment of educational software. Offers suggestions for potential users, for practitioners of teacher education, and for the developers of…

Addresses solution nonmetal determinations on a fundamental level. Characterizes research in this area of chemical instrumentation. Discusses the fundamental limitations of nonmetal atomic spectrometry, the status of nonmetals and atomic spectroscopic techniques, and current directions in solution nonmetal determinations. (CW)

Student responses in evaluating a chemistry program were used to map out significant objectives of the program, courses most liked, courses least liked, and the qualities of these courses and their lecturers. The significant objectives were those related to practical work, followed by those dealing with the world of work. (Author/MLW)

Illustrates statistical data on spending money for research and development in chemistry and chemical engineering. The data is presented by overview, federal government, industry, universities and colleges, and international. Provides many tables and graphs. (YP)

Discusses and suggests some solutions for three problems related to chemistry laboratory management, including disappearance of teaching assistants, check in/out procedures, and slow students. (YP)

Conceptions of (n=13) grade-11 chemistry students via interviews were grouped into 6 categories related to students' preferred explanations for solubility phenomena. Argues that an understanding of the typical conceptions used by students should form an integral component of chemistry teaching, both as points of origin for lesson planning and for…

Analyzes the information-seeking patterns of a group of research physicists and chemists and compares them with the information seeking activities of a group of social scientists obtained from a previous study. The impact of developments in information technology on the information or communication patterns of all of the researchers is considered.…

The experimental/analogy group scored significantly higher than the control group on a posttest question that required the definition of diffusion (n=77 community college students). Hypothetico-deductive reasoning skill was significantly related to correct application of the diffusion concept to a change from the misapplication of the polarity and…

Involves secondary students in a study designed to allow investigation into how different levels of information presented by various technologies (chemical indicators, pH meters, and microcomputer-based laboratories-MBLs) affected students' understanding of acid, base, and pH concepts. Results showed that students using MBLs exhibited a greater…

A Michigan court has ruled that a Wayne State University (Michigan) chemistry professor appropriated a trade secret from a Massachusetts chemist for whom he was consulting and incorporated it into his own patent application, violating a written agreement. The university contends its pursuit of the patent was not improper. (MSE)

Many of the characteristics that make the Windows 3.1 software popular in other settings are useful for instruction. Features and accessories that can enhance teacher productivity include task switching, object linking and embedding, and object packaging. Users can take advantage of Windows-compatible shareware (an example suitable for chemistry…

Discusses how laboratory skills or experiences learned in a chemistry course can be used to help students to better understand physics. (ZWH)

Presents an introduction to a unit on the periodic table in which students are asked to assume the roles of the element families. (MKR)
