Presents a buffer demonstration which features visualization of the effects of carbon dioxide on pH. Background information, list of materials needed, procedures used, and a discussion of results obtained are included. (JN)

Monitoring student performance on microcomputer drill and practice programs over time provides evidence that students learn from the programs at different rates and that programs differ in the rates at which they impart learning to students. Implications of these and other findings for science teaching are addressed. (JN)

Discusses six educational and economic reasons for using demonstrations in a high school chemistry classroom. Also discusses reasons for doing lecture demonstrations as an integral part of college chemistry instruction. (JN)

A senior-level, elective course on synthetic fuels was developed for chemistry and chemical engineering majors. The topics covered in this course, instructional strategies used, and independent student projects are described. (JN)

Computer Assisted Practical Evaluation (CAPE) is a FORTRAN computer program which students use to verify answers obtained from experimental data. Generally, whenever an incorrect answer is supplied, students are asked to redo calculations and submit a revised value. Advantages and use of the program with chemistry classes are described. (JN)

Presented is a bibliography of articles published in the "Journal of Chemical Education" (1968-1983) which focused on industrial chemistry. Items are listed under these headings: real world of industrial chemistry; industrial notes; subject matter articles; industrial chemistry experiments/demonstrations; academic-industrial interface;…

Background information (theory), apparatus used and procedures required are provided for an experiment which involved the measurement of the deviations of carbon dioxide from perfect gas behavior by means of pressure/volume (pV) measurements at pressures of up to 20 atmospheres at room temperature. (JN)

Describes an experiment involving the preparation of copper iodide that gives stoichiometric results. Materials needed and procedures are discussed along with ideas on different ways to analyze the data. Pertinent chemical equations are presented. (BC)

The Chemical Education for Public Understanding Project is a three-year pilot project designed to provide the public with accurate information on uses and hazards of chemicals, ranging from control of garden pests to types of toxic wastes generated by industry. Discusses project aims and educational materials to be developed. (JN)

Presents a series of syntheses in which poly-4-vinylpyridine is substituted for pyridine or other tertiary amines, avoiding some of the safety problems associated with traditional reagents and providing a readily recoverable and recyclable reactant. Background information, procedures used, and results are included. (JN)

Describes a two-semester course designed to explain the economic aspects of the chemical industry to a variety of students in chemistry or related fields. Includes course objectives, suggested teaching methodology, and content of eight course categories (such as basic skills exercises, elucidation of specialty products, and alternate process…

Background information, procedures used, and typical results obtained are provided for an experiment in which gas chromatography is used to prove the application of quantum symmetry restrictions in homonuclear diatomic molecules. Comparisons between experimental results and theoretical computed values show good agreement, within one to two…

Describes a curriculum development project in which the Science Education Center of the University of Oklahoma and the science department of Norman (Oklahoma) High School prepared and classroom tested complete courses in biology, chemistry, and physics using the learning cycle principles of exploration, conceptual invention, and discovery. (JN)

Offers a model of scientific thought based on the multidisciplinary integration of the sciences. Stresses the importance of constructions/deconstructions of meanings, codifications/decodifications of symbols, and structurations/destructurations of conceptual operations in the development of scientific thought and in the modification of human…

Dynamic crystal model kits are described. Laboratory experiments in which students use these kits to build models have been extremely successful in providing them with an understanding of the three-dimensional structures of the common cubic unit cells as well as hexagonal and cubic closest-packing of spheres.
