Explains two approaches for stimulating the intellectual development of the student from the concrete to formal operations level. One method involves experimentation and critique during which the student deduces the principle. The second involves a lecture approach that utilizes the creation of the discrepant event. (GS)

Describes an experiment designed to augment textual materials conducive to the inquiry approach to learning. The experiment is the culminating experience in a series designed to illustrate the fundamental nature of the atom: its quantized energy nature, its electrical nature, and its combining ability. (Author/GS)

Reports on course revisions made on the basis of input from discussions with chemistry teachers and pupils, a questionnaire administered to chemistry teachers in 200 schools, and details of the performance of candidates on the Nuffield 0-Level examination. Revised materials include materials for the pupil, for the teacher, and the exam. (GS)

Reflects on the declining enrollment of students in first year chemistry courses. Suggests causes for this decline which include disenchantment with science, capricious chemical industry recruitment, exaggerated employment difficulties, and teaching approaches at both the secondary and tertiary levels. (GS)

Presents abstracts of the plenary lectures and contributed papers of a conference that covered the following areas: laboratory organization, integrated laboratory, instructional aids and equipment, computers, and general chemistry laboratory. (GS)

Presents a flowchart that is used in the elementary qualitative analysis of a single salt. (GS)

Washington, D.C. has been associated with many distinguished chemists. Since its incorporation in 1802, a steady stream of chemists have made impressive contributions to chemical science, health, information science, minerology, food science and other areas. The majority of these chemists have been associated directly or indirectly with the…

This instructor's manual presents information for a training course in analytical methods for inorganic and organic chemical contaminants listed in the interim primary drinking water regulations. Topics focus on: (1) pre-course activities, including course logistics, equipment, and facilities; (2) sample agendas; (3) lesson plans for specific…

This document contains lab activities, problem sets, and a tape script to be accompanied by a slide show. The minicourse covers the following topics of general chemistry: kinetic-molecular theory, the Bohr atom, acids, bases, and salts, the periodic table, bonding, chemical equations, the metric system, computation of density, mass, and volume,…

This is the sixth annual report of the U.S. Trade Commission on domestic production and sales of synthetic organic chemicals and the raw materials from which they are made. The report consists of 15 sections, each covering a specified group (based primarily on use) of organic chemicals as follows: tar and tar crudes; primary products from…
