Announced is an approval service for associate degree programs in chemical technology at two-year colleges. Features of the program and ways that institutions may become involved in the program are discussed. (CW)

Describes using the course question: "How does chemistry (or biology) impact my personal life and society?" This course question is presented to students and forms the basis of the final exam. Students evaluate a current-events article using the question as a framework. Students explore the relationship between chemistry (or biology) and their…

Describes the use of practice weighings and handling of fluorescent compounds to assist in teaching students safe-handling techniques. (PR)

The history of atomic theory is outlined from earliest times up to the orbital model and describes a corresponding teaching method. The historical part of the paper emphasizes social and philosophical aspects in the development of atomic theory. The second part of the paper describes a method for teaching this material at the secondary level.…

Describes concrete demonstrations on the states of matter. In the first demonstration, students represent molecules; and, in the second demonstration, moth balls are heated to produce a change of state. (PR)

Describes a science project in which students make models of polymers using polyvinyl alcohol solution. Students make T-shirts using polymer paint to remind them of their activities. (MDH)

Describes a study of Indian and Fijian pre-service primary teachers that reveals how many hold alternative conceptions of fundamental scientific concepts. Focuses on conservation of matter. (DDR)

Lists 67 published or marketed chemistry games organized under the following categories: (1) general knowledge; (2) elements and atomic structure; (3) nomenclature, formulas, and equation writing; (4) chemical reactions; (5) solutions and solubilities; (6) organic chemistry, and (8) miscellaneous subjects. Includes a brief description of each…

Introduces puzzles that proved challenging and popular in the Mexican Chemistry Olympiad. Presents data showing that mainstream general chemistry students at the University of Nebraska-Lincoln enjoyed the puzzles and were challenged by them. (WRM)

Describes a conceptual typology of models to help teachers select models appropriate to the cognitive ability of their students. Presents an example of how the systematic presentation of analogical models enhanced an 11th-grade chemistry student's understanding of atoms and molecules. Makes recommendations for teachers. Contains 28 references.…

A greater role for the history and philosophy of science in science education can only be realized if it is based on both a credible analytical approach--such as that of Lakatos--and if the evolution of a sufficient number of major themes in science is known in suitable detail. Considers chemical kinetics as an example topic. Contains 62…

Describes an experiment in which students determine the density of Coke and Diet Coke, consider density as an intensive property, and compare the accuracy and precision of different types of glassware. (WRM)

Discusses the issues involved in creating an Internet-based chemistry class, including presentation of material, testing, lab work, and administrative support. (WRM)

Presents an historical background of changes in the Maltese science curriculum for boys and girls. Describes the levels of the Maltese educational system and briefly summarizes subject areas and objectives for physics, biology, chemistry, mathematics, and the arts taught in schools from preschool to postsecondary education. (YDS)

Describes a unit on biodiesel from a socio-critical chemistry teaching approach aimed at improving student participation and decision making. Explores the use of biodiesel (chemically changed vegetable oils), especially in Europe. The unit proved to be successful as students participated enthusiastically and social and scientific goals were…
