This experiment demonstrates the reduction of inorganic sulfate to sulfide in the pore water of estuarine muds. Procedures involve the incubation of mud samples for varying amounts of time followed by gravimetric determination. (Author/SA)

Presents the results of a survey study conducted in the United Kingdom to identify the opinions of 65 chemistry teachers from Middlesex and Buckinghamshire about the use, costs, design, and content of 0 level and A level chemistry books. (HM)

Describes an experiment, designed for use in the undergraduate laboratory, that measures the bond energies of molecules using a small commercial mass spectrometer and low-cost digital voltmeters. (BT)

Describes an undergraduate chemical engineering course which has been offered at the Georgia Institute of Technology. The objectives, structure, instructional materials and content of this course, which emphasizes the structure and usage of computer-aided design systems, are also included. (HM)

Focuses on the problems facing the chemical industry during the decade ahead. Government regulations, political activity by the industry, environmental concerns of the public, research and development, and competition are the major concerns discussed. (SA)

Year 11 students investigated the real-world problem of whether screws are really brass. It allowed them to use the colorimeter and computer interface in a way that was easily understood and models normal practice in testing laboratories. Screws were dissolved in nitric acid and their absorbance of red light was compared with a standard curve.…

Presents the topic of linking the presence of life on Earth with the chemical evolution of the universe as a whole. The approach involves examining issues related to the biochemical unity of living matter and the chemical evolution of the galaxy. (DDR)

Discusses the writings of Homer W. Smith, a physiologist who wrote novels, histories of religion, textbooks, and a book on the kidney for the general reader. Smith's writing skills remind students that biologists are as multidimensional as the rest of the population. Smith shows that all parts of life are interrelated as they enrich and shed light…

Describes a project designed to increase science literacy in the general public by bringing hands-on experiments with real-world applications to public school students. Provides the history and an outline of the program. (DDR)

Describes the design of several CD-ROMs with different strategies and foci for teaching general chemistry with large databases of visual information. Presents a sample search with a CD-ROM. Discusses teacher resources including animations, visual databases for presentations, demonstration manuals, laboratory manuals, and encyclopedias as well as…

Describes an introductory chemistry course that incorporates student-oriented approaches such as inquiry and problem-based laboratories. Provides an overview of the modules. (Contains 16 references.) (DDR)

Introduces a chemistry unit, the "Evolving Atom", based on a problem-based learning approach designed for non-science majors. Uses the case method to address memory loss in mice during instruction. (Contains 14 references.) (YDS)

Surveys of predominantly Asian students in college preparatory chemistry classes examined their views of themselves as scientists and readers and writers of science material. Results indicated that gender was related to students' views of themselves as scientists and writers of science. Family and extracurricular science activities were powerful…

Describes research that documents the falsification of laboratory results by chemistry and physics students. Discusses some factors that encourage students to fabricate results and why some students do not feel the need to falsify data. Contains 16 references. (DDR)

Describes a paraphrasing technique from a methodology called Teaching for Thinking as a means to promote more effective discussion in small group sessions. A paraphrase that highlights assumptions or that provides an interpretation of a student's statement encourages students to think beyond what they have said. Critiques sample teacher responses…
