This report explores the evolutionary process of the concepts of accountability and performance contracting from their inception through mid 1970-71. Six major topics are discussed: (1) ideological, managerial, and pedagogical underpinnings, (2) definitions and history of the concepts, (3) five performance contracting projects, (4) the political…

In two separate paired-associate learning experiments each employing 40 university students as subjects, the contribution of individual differences (IDs) in arousal to short- and long-term retention was investigated using IDs in salivary response to lemon juice stimulation as an index of arousal. Experimental subjects were pre-selected out of 184…

While science films can differ widely in their content and purpose, the making of such films rests on a pattern of principles, techniques, and matters of routine. This book traces that pattern and presents descriptions of how some particular problems were tackled previously. The history and state of the medium are overviewed, with information on…

This report on speech research contains 21 papers describing research conducted on a variety of topics concerning speech perception, processing, and production. The initial two reports deal with brain function in speech; several others concern ear function, both in terms of perception and information processing. A number of reports describe…

This report provides statistical and narrative data on innovative projects and methods developed in Fairfax County's Center for Effecting Educational Change. These study activities focused on effecting changes in the kindergarten, child study, fine and performing arts, and educational technology programs. A broad outline provides an overview of…

This report describes an experiment which tests the effectiveness of a multimedia, continuous learning program in comparison with that obtained in a traditional Spanish language course. Results of the Modern Language Tests for Spanish 1 indicate that experimental and control groups were equal at the conclusion of one year of study in both the…

This paper proposes a schema that will provide the analytical clarity needed for generating insights into pedagogical issues and, consequently, for developing curriculum efficiently. The schema has four terms: learning assumption, instructional hypothesis, teaching technique, and teacher performance. A learning assumption postulates that an…

This volume is one of the series for the Chemical Technician Curriculum Project (ChemTeC) of the American Chemical Society funded by the National Science Foundation. It consists of discussions, exercises, and experiments on the following topics: the nature of reversible processes, equilibrium constants, variable reaction tendencies, practical…

This volume is one of a series for the Chemical Technician Curriculum Project (ChemTeC) of the American Chemical Society funded by the National Science Foundation. It consists of discussions, exercises, and experiments on the following topics: amino acids and proteins, carbohydrates, synthetic polymers, other natural products, chemical separations…

Intended to supplement a regular program, this pamphlet provides background information, related activities, and suggestions for other activities on the subject of nitrate as a water pollutant. Two activities related to plant nutrient pollution, nitrate filtration and measuring mitrate used by plants, are explained in detail, outlining objectives,…

AN EXPERIMENTAL SUMMER COURSE IN ECONOMICS WAS PRESENTED TO 53 PREFRESHMAN COLLEGE STUDENTS. THE 6-WEEK COURSE ENTAILED LECTURES AND DISCUSSIONS. ONCE A WEEK THE ENTIRE CLASS WAS BROKEN INTO SMALL GROUPS THAT WOULD MEET WITH A SECTION INSTRUCTOR OR LECTURER TO DISCUSS A SPECIFIC READING. AT LEAST ONCE A WEEK, A FILM RELEVANT TO THE COURSE WAS…

A resource unit on the marine sciences is described. Designed for eighth-grade students with some basic science background, the unit can be taught in a minimum of four weeks. Content includes emphasis on the biological, chemical, and physical sciences. Each lesson contains objectives, goals, materials, and follow-up activities (often an…

Describes laboratory activities which relate the mass, volume, density, and radii of atoms through the assumption that the smallest unit of matter is a cubic box containing one atom. From calculations based on macroscopic materials, the author feels that the concept of an atom may be better developed. (CP)

Discovery teaching advocates minimal teacher guidance. Materials from two curriculum development projects were evaluated with respect to this guidance. Results indicate a considerable discrepancy between curriculum intention and reality, as measured by the degree of teacher guidance afforded in the projects' instructional materials. (CP)

Describes an advanced analytical chemistry laboratory experiment developed for the determination of the performance parameters of a spectrophotometer. Among the parameters are the baseline linearity with wavelength, wavelength accuracy and respectability, stray light, noise level and pen response time. (HM)
