Describes a general chemistry experiment which uses infrared spectroscopy to analyze inorganic ions and thereby serves to introduce an important instrumental method of analysis. Presents a table of eight anions and the ammonium ion with the frequencies of their normal modes, as well as the spectra of three sulfate salts. (RR)

The purpose of this paper is to provide a set of criteria within a format that teachers, student teachers, and supervisors can use to better understand what inquiry is and how to evaluate the extent to which it is being incorporated into classroom activities. The evaluative criteria are organized into an instrument and are divided into the…

This report presents the procedures, findings, and conclusions of a study designed to determine the effects of instrumentation of freshmen chemistry laboratory on achievement and interest in chemistry. Students in each of 80 matched pairs were randomly assigned to the two types of laboratory. One group used instrumented laboratory techniques and…

An instrument to assess specific attitudes toward humanistic teaching strategies as well as toward science teaching was designed. (Author/GA)

Indicates that the current philosophy of laboratory experimentation and instrumentation is creating students that are not well versed in basic principles of chemistry. (GS)

Describes modules designed to enable a student to learn a measurement technique and familiarize himself with measurement instrumentation independently of a laboratory course. Presents an example of a module involving the measurement of electrical resistance and lists other modules that have been developed. (GS)

Describes a combined demonstration and student experiment course to illustrate fundamental techniques, instrumentation, and concise report writing. Describes experiments including tensile tests, heat treatment, equilibrium diagram, microexamination, strain measurement, and recrystallization. (GH)

Describes the Teacher Orientation to Science Instruction (TOTSI) instrument, which comprises a set of statements on eight characteristics of science teaching. TOTSI evaluates teacher assumptions to indicate what type of curriculum best suits the teacher's abilities and preferences. (MLH)

Includes a syllabus for lecture and laboratory in a course emphasizing principles of operation rather than trouble shooting. (GH)

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.…

Explains some experiments involving thermal methods of analysis for undergraduate chemistry laboratories. Some experiments are: (1) the determination of the density and degree of crystallinity of a polymer; and (2) the determination of the specific heat of a nonvolatile compound. (HM)

Identifies the properties and characteristics of supercritical fluids. Discusses the methodology for supercritical fluid chromatography including flow rate, plate height, column efficiency, viscosity, and other factors. Reviews instruments, column types, and elution conditions. Lists supercritical fluid data for 22 compounds, mostly organic. (MVL)
