The purpose of this study was to ascertain the functions of the county vocational education director in California as perceived by selected groups of vocational education leaders. The functions were limited to the service responsibilities of the position, exclusive of its administrative responsibilities for the improvement of instruction. An…

The purpose of this research was to conduct a preliminary analysis of a new instrument designed to measure the psychological environment of the classroom. The instrument, the Classroom Environment Index (CEI), has been developed in an initial form. The structure was essentially the same as the other Syracuse Indexes (College Characteristics Index,…

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)

Without an efficient, effective data storage and retrieval system, no performance based teacher education assessment plan will succeed. Concepts and techniques fundamental to the establishment of such a system are described. (MJB)

Presents a case study of how the review and clearance procedures are operating for evaluation instruments used in collecting information in connection with studies for the U.S. Office of Education. The review procedures are defective: They consume too much time. They are very costly. The results are unproductive. (Author/JM)

Describes a way to use computers in teaching chemistry, in this case in a demonstration lesson on supercooling using a thermister in a game port to interface the computer with cooling phenyl salicylate. Discusses the advantages over the traditional method of instruction. (CW)

Reviews background of atomic absorption spectrometry techniques. Discusses problems encountered and precautions to be taken in determining trace elements in the parts-per-billion concentration range and below. Concentrates on determining chromium in biological samples by graphite furnace atomic absorption. Considers other elements, matrices, and…

Describes an experiment combining qualitative and quantitative information from hydrogen nuclear magnetic resonance spectra. Reviews theory, discusses the experimental approach, and provides sample results. (JM)

Presents excerpts of a survey on the instrument status in chemistry departments and the perceived needs of those departments for new instruments. Responses are based on data from 32 chemistry departments at major research institutions, 71 departments at smaller schools, and 13 chemical engineering departments. (JN)

Discusses functions of automated instrumentation systems, i.e., systems which combine electrical measuring instruments and a controlling computer to measure responses of a unit under test. The computer-assisted tutorial then described is programmed for use on such a system--a modern microwave spectrum analyzer--to introduce engineering students to…

Reviews three functions performed by modern computing integrators: (1) data acquisition; (2) data processing; and (3) communication. Also shows with examples how new electronic components enhance the functions of this popular analytical instrument in those areas. (JN)

Describes a comprehensive nuclear magnetic resonance (NMR) experiment designed to introduce undergraduate organic chemistry students to measurement/interpretation of NMR parameters. Students investigate chemical shift analysis, spin-spin coupling, peak integrations, effect of deuterium oxide extraction, and comparisons with literature spectra;…

Before researchers can adequately establish empirical relationships between teacher behavior as an independent variable and student achievement as a dependent variable, when studying teacher effectiveness, they must deal with the problems of instrumentation, methodology, and statistics. (MM)

Discusses the principles, construction, and operation of an apparatus which serves to demonstrate the non-colinearity of the angular velocity and momentum vectors as well as the inertial tensors. Applications of the apparatus to teaching of advanced undergraduate mechanics courses are recommended. (CC)
