The Class Activities Questionnaire (CAQ) was used to compare a Canadian high school participating in a research project employing an information retrieval system with another not involved in the project. This paper evaluates the validity of the CAQ as a measurement instrument for this study. The CAQ was administered to 1831 students, 806 Science…

This report presents a 2-year, longitudinal evaluation of the effects of a major training program on two State Educational agencies and four local educational agencies. The program was designed to improve the process of organizational planning in educational systems. The evaluation procedure involved interviewing top administrators who underwent…

These five study papers (1) analyze recent performance contracting experiences, (2) discuss education voucher proposals and prospects, (3) assess potential federal revenue sources for education, (4) provide an inventory of federal programs in aid to education, and (5) examine the status of nonpublic education. The first study suggests that schools…

This paper considers language development among children and discusses the influence of the learning environment in the acquisition of language use as distinct from language structure. The results of the five studies reported here suggest that the child is aided by what he is encouraged to say, not simply by what he hears, and that adults seem to…

The present study, part of a larger investigation, attempted to examine the separate and joint effects of succession and effectiveness on administrative processes in laboratory-created 3-level formal organizations. Specifically, the investigation concerned itself with the impact of these two elements on communication relationships between managers…

Conflicting evidence as to the presence or absence of generalization in classroom behavior modification programs prompted this study of the conditions of generalization. During the experiment, behaviors operationally defined as competitive or cooperative were reinforced in certain game situations. Then the generalization of this training over…

This volume of working papers includes eight papers dealing mainly with experimental topics in linguistics and in phonology and speech. The following articles are in the collection: "Units in Speech Perception,""The Temporal Realization of Morphological and Syntactic Boundaries,""Comparison of Controlled and Uncontrolled Normal Speech Rate,""Word…

This seminar paper explores the role that historians of technology can play in the reevaluation of the relationship between technical and social change. Historians of technology need to ask questions about the nontechnological aspects of society which have influenced technical change in the past. In the realm of ideas, historians should check…

A research project conducted during the 1976-77 academic year in the Baltimore City Public Schools is investigating the effect providing staff development to teachers on how to teach with learning hierarchies will have on students' achievement scores and rate of learning. Twenty teachers participating in the study are taking a year-long course on…

The authors describe a one-quarter, undergraduate teacher education experience that involved a high level of personal freedom and synergy in an attempt to develop humanistic teachers. Twenty-three juniors and seniors were involved in the program, which took the form of an unstructured block of courses in mathematics, science, and social studies.…

Describes a laboratory exercise designed to introduce students to the Pourbaix diagram for cobalt. Discusses the use of a Pourbaix diagram as a potential-pH plot which displays some of the most thermodynamically stable species for a given element. Outlines a laboratory demonstration and a student investigation. (TW)

Outlines five simple and inexpensive methods for students to use in identifying unknown substances. Provides a table of general solubility data for ions, a suggested list of unknown substances that can be tested using the methods described, and some prelaboratory information. (TW)

Uses capillarity as an example of a problem in physics which has been explained mathematically in two different ways. Argues that only one explanation is indeed valid and demonstrates this opinion through experimentation and discussions. Proposes that mathematics should be used in physics as a tool to predict, not to explain. (TW)

Focuses on the development of a pilot unit for use in an advanced separations process laboratory in an effort to develop experiments on such processes as reverse osmosis, ultrafiltration, adsorption, and chromatography. Discusses reverse osmosis principles, the experimental system design, and some experimental studies. (TW)

Discusses some interesting kitchen chemistry experiments. Describes the use of baking aerators and baking powders in an inexpensive experiment. Outlines several demonstrations to follow up the experiment and to illustrate other chemical principles. (TW)
