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…

This study examined the impact of college general education science-technology-society (STS) and Physics courses on students' views about STS interactions. Two samples of convenience took part in the investigation, one consisting of 138 students enrolled in an STS course, and the other of 122 students enrolled in a physics course. Data were…

The research described in this paper leads to an instructional design approach which is an alternative to the consideration of such issues as mathematical skills or level of cognitive development. The approach uses an analysis of traditional instructional tasks to specify the underlying cognitive processes and structures necessary for the…

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…

The major task in solving a physics problem is to construct an appropriate model of the problem in terms of physical principles. The functions performed by such a model, the information which needs to be represented, and the knowledge used in selecting and instantiating an appropriate model are discussed. An example of a model for a mechanics…

Describes techniques and equipment intended to both improve laboratory measurements and also form a background for more advanced work by introducing the concepts of electronic and digital circuits. (GS)

Presents the advantages and disadvantages associated with the canned computer lab from the educational and software aspects. Summarizes two years of experience with canned labs and gives an example of a program and a typical student output. (GS)

Describes a method for the measurement of the velocity of sound in various liquids based on the Raman-Nath theory of light-sound interaction. Utilizes an analog computer program to calculate the intensity of light scattered into various diffraction orders. (CP)

Two laboratory investigations are described: (1) staining chromosomes in root tips and (2) demonstrating pollen tube growth. (LS)

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 laboratory experiment in which the position of the double bond in an alkene is determined by identifying its ozonolysis products. This experiment can also be used to introduce the technique of gas chromatography. (MLH)

Three brief articles present (1) the use of adrenaline related to the preparation and properties of amines; (2) a non-lecture approach to organic chemistry; and (3) the use of comic books in teaching chemistry. (RH)

Describes an undergraduate organic chemistry laboratory experiment which utilizes the Gabriel Synthesis to demonstrate the acidity of imides and to provide an example of nucleophilic substitution reactions. The experiment also demonstrates the laboratory techniques involved in simple and steam distillation, filtration, extraction, and…

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)
