Many students face chemistry courses with a sense of fear and foreboding because it is a required course. Yet at the same time, fundamentals of chemistry have become intertwined in countless professions to say nothing of its growing importance in our everyday lives. Educators must bridge this dichotomy between attitude and importance. This paper…

The main objective of this study is to construct models based on strategies students use to solve chemistry problems and to show that these models form sequences of progressive transitions similar to what Lakatos (1970) in the history of science refers to as progressive 'problemshifts' that increase the explanatory' heuristic power of the models.…

Among the 22 tests cited in this bibliography are end-of-course tests, tests of the American Chemical Society, and chemistry item banks. This document is one in a series of topical bibliographies from the Test Collection (TC) at the Educational Testing Service (ETS) containing descriptions of more than 18,000 tests and other measurement devices…

Vietnamese students now enrolled in American high schools incur an extremely special need in English. After being taught subject matter disciplines in Vietnamese for many years, and while English is still a foreign language for them, these students are bound to go through two linguistic processes. First, while reading or sitting through lectures…

This article discusses ways in which secondary polytechnical schools in Russia can acquaint pupils with the basic ideas of applied chemistry. Students must be guided so that they can choose a vocation in accordance with their personal inclinations and the needs of society. (Author/RM)

Describes the use of disc or ring magnets magetized axially and iron discs, in conjunction with an overhead projector, as a model of nuclear structure and of complete molecules. (GS)

Describes the findings of a questionnaire, completed by a sample of chemistry teachers in England, concerning inservice needs. Statistical analyses are provided for the differences in opinion about reasons for taking inservice courses and what course contents were preferred. (MLH)

Describes secondary and higher chemical education in Canada, including credit hour requirements, types of curricula used, and administrative details. The control of education is considered the right of each of the 10 provinces while science policy and the funding of research is largely controlled by the federal government. (MLH)

Describes an undergraduate biochemistry experiment which involves the preparation and kinetics of an oxidation-reduction enzyme system, methemoglobin reductase. A crude enzyme extract is prepared and assayed spectrophotometrically. The enzyme system obeys Michaelis-Menton kinetics with respect to both substrate and the NADH cofactor. (MLH)

Gives highlights of two symposia on chemical education held in Madrid in September, 1975. Topics included the use of educational technology, teacher training, and curriculum. (MLH)

Describes an undergraduate chemistry experiment in which the concentration of chloride, fluoride, or bromide ions can be quantitatively determined by titrating with mercury (II) ions. (MLH)

Describes methods for teaching the mole concept, including analogous calculations involving household objects, and the use of a cardboard wheel showing the interrelationships between moles, molecular weight, and the gaseous molar volume. (MLH)

Describes a biochemistry laboratory course in which students worked in groups; each group selected three of nine possible experiments. Each student was responsible for using the chemical literature to obtain detailed procedures for performing the experiments, and submitted formal reports on each experiment. (MLH)
