A program designed to increase studnet interest and provide motivation in a third-year systems and measurements laboratory in mechanical engineering is provided. The philosophy of the course, instructional techniques, equipment design (including schematics and photographs), suggested activities, and student reactions to the course are presented.…

This Likert-type attitude questionnaire was developed to evaluate the attitudes of secondary school students toward science. The questionnaire contains 5 subscales each comprising 12 item (6 positive, 6 negative). The subscales relate to the following 5 attitude objectives: interrelationship between sciences, relationship of science to other…

Describes some undergraduate laboratory experiments on thermoanalytical techniques which deal with both organic and inorganic compounds. (GA)

Describes use of a Fresnel biprism to demonstrate double-slit interference with polarized light. Discusses polarization and phase properties of a randomly polarized gas. (JM)

Describes an advanced high school chemistry course that exposes students to a wide variety of modern, realistic instrumental techniques. The laboratory syllabus for the course (which uses the textbook "Organic Chemistry" by Morrison and Boyd) is included. (JN)

Biology teachers at Ithaca College have developed a course in experimental methodology and instrumentation that teaches beginning biology students the need for accuracy and precision in measurement. This course is described. (JN)

Reports results of a survey of college professors (N=146) on the present use of chemical instrumentation in undergraduate chemistry curricula of four-year colleges and universities in the United States. Uses in general, organic, analytical, physical, integrated, and research chemistry courses are noted. (JM)

Describes an experiment designed to acquaint students with the theory and applications of anodic stripping voltammetry (ASV) as well as such ASV problems as contamination associated with trace analysis. The experimental procedure, instrumentation, and materials discussed are designed to minimize cost and keep procedures as simple as possible. (JM)

Presents an experiment in thermometric titration used in an analytic chemistry-chemical instrumentation course, consisting of two titrations, one a mixture of calcium and magnesium, the other of calcium, magnesium, and barium ions. Provides equipment and solutions list/specifications, graphs, and discussion of results. (JM)

Reviews a noncommercial educational game (Polymerlab) and changes made in GASLAWS (adaptation of mainframe program used in computer-assisted instruction). Describes programs on simulation of molecular speed distributions; interfacing microcomputers to make laboratory measurements; a course in microcomputer-instrument interfacing and measuring and…

In studies relating teacher effectiveness and student achievement, the establishment of empirical relationships between teacher behavior as an independent variable and student behavior as a dependent variable is essential. Problems concerned with instrumentation, methodology, and statistics of such research are discussed. (BT)

Discusses the production and structure of a sequence of optical crystals which can serve as one-, two-, and three-dimensional diffraction plates to illustrate diffraction patterns by using light rather than x-rays or particles. Applications to qualitative presentations of Laue theory at the secondary and college levels are recommended. (CC)
