Describes events leading to a flood in the Wehr Chemistry Laboratory at Marquette University, discussing steps taken to minimize damage upon discovery. Analyzes the problem of flooding in the chemical laboratory and outlines seven steps of flood control: prevention; minimization; early detection; stopping the flood; evaluation; clean-up; and…

Describes a unit on river pollution and analytical methods to use in assessing temperature, pH, flow, calcium, chloride, dissolved oxygen, biochemical oxygen demand, dissolved nitrogen, detergents, heavy metals, sewage pollution, conductivity, and sediment cores. Suggests tests to be carried out and discusses significance of results. (JM)

Describes using high school chemistry grades along with mathematics scores from the Scholastic Aptitude Test to predict college chemistry grades. Discusses rationale for the choice of predictive measures, the effect of teaching assistants, and supplemental study skills workshops on the grade received. (JM)

Discusses indoor air pollution in general and formaldehyde in particular, citing major sources of formaldehyde in home building materials and home furnishings. Also describes a laboratory procedure necessary to test for formaldehyde levels in the air and in materials. Includes list of equipment required. (JM)

The paper considers the main results and some educational implications of the TIMSS 2003 assessment conducted in Serbia in the fields of the science achievement of Serbian eighth grade students and the science curriculum context of their achievement. There were 4264 students in the sample. It was confirmed that Serbian eighth graders had made…

Science curricula typically do not capitalize on the hands-on, self-initiated learning style of young children. This book provides a comprehensive, developmentally appropriate approach to science education with young children, with special attention to physics and chemistry. The book's introductory chapter is followed by chapters on: (1) science…

This monograph focuses on the chemistry of lipids and enables teachers to introduce their students to the concepts and processes of industrial chemistry and relate these concepts to the consumer products students encounter daily. This teacher resource module is organized into sections that provide information on how to use the resource module, how…

Background information on natural polymers, synthetic polymers, and the properties of polymers is presented as an introduction to this curriculum guide. Details are provided on the use of polymer products in consumer goods, polymer recycling, polymer densities, the making of a polymer such as GLUEP, polyvinyl alcohol, dissolving plastics, polymers…

This report is one of a series of reports from a research project that focuses on the evaluation of laboratory work in secondary schools. The study focuses on 12 different laboratory tasks from the biology and chemistry courses of the Finnish comprehensive school. Secondary students (N=212) were observed during laboratory sessions and analysis of…

This volume is a collection of 12 papers of particular interest to librarians specializing in chemistry. The articles discuss the educational role of librarians in several types of institutions, offer new ways of providing information, and describe ways of coping with increasing prices and formats of journals. The first paper offers an overview of…

The purpose of this study is to describe types and structural properties of instructional activities used by physics and chemistry preservice teachers (N=4) during their teaching of pupils 14 to 16 years old. The study involved the observation and tape recording of 64 classes with all tapes transcribed verbatim. Analysis involved the decomposition…

This report, covering 1,677 faculty in the field of physical science, general, is part of an annual national survey of faculty salaries. The survey consists of two parts: one covering public and one covering private four-year colleges and universities. Data for the baseline year 1995-96 and the 1998-99 trend year were collected for full-time…

The concept of physical and chemical change is far from being the clearest and most self-explanatory concept in the world. If a number of chemists are asked to define physical and chemical change, there may well appear to be a fair degree of uniformity in their answers, until a few examples are suggested. When chemists are asked to place a variety…

Discusses responsibilities for providing safe experiments and for teaching about safety. Provides lists of references on chemical safety and regulated/potential carcinogens. Also discusses general laboratory safety procedures including waste disposal and recycling of solvents. (JM)

Describes a reading assessment technique (different from most reading level evaluations) involving identification of the concepts for study, categorizing the statements about the concept, and analysis both within and between texts. Analysis allows teacher to make judgments relating to convenient order of concepts, rate of development, and…
