The purposes of the present investigation were to illustrate the applicability of categorization methodology for several empirical situations and to draw implications regarding the use of such methodology in examining categorical data. In using three tasks--two designed to measure cognitive dimensions (e.g., categorizing countries and categorizing…

A task of regional educational laboratories is to provide information to state and local education policy makers. The new focus on policy reflects a change in the labs' knowledge base and audience. The subsequent move into the political arena has created risks for the labs, which have responded to the new task in different ways. The nature of the…

This study examines the integration of heterogeneous bibliographic information resources from geographically distributed locations in an automated, unified, and controlled way using abstract data types called "classes" through the Message-Object Model defined in Smalltalk-80 software. The concept of achieving data consistency by…

The paper is the fifth of a series of working papers developed by a project which conducted a cooperative study of existing student study team (SST) processes in nine California special education local plan areas. The working papers augment the final report by providing detailed descriptions of the methods used and the preliminary findings. This…

Beyond the first several thousand most commonly used words in a language, direct vocabulary instruction is not efficient. Use of inferential skills then becomes the most effective way of learning new vocabulary; it is the way native speakers build their 60,000 word vocabularies. Because the skill is not automatically transferable, it must be…

This follow-up study, which was part of a larger ongoing longitudinal project, compared early infant-parent attachment relationships to aspects of both parents' and children's mental representations of attachment when children were 6 years old. The sample consisted of 50 mothers, fathers, and children of predominantly upper-middle class social…

Three studies were conducted to investigate reasons for the difficulties that children under 5 years of age experience with class inclusion tasks. The studies tested the claim that such tasks have a structural complexity that is beyond the children's processing ability. In experiment 1, class inclusion tasks were compared with other classification…

Three studies examined the domain of concepts about dinosaurs in order to assess how the domain might be structured in 4- through 7-year-old children's representations and to explore how the knowledge might be used. Findings indicated that significant differences exist in the way expert and novice children's representations are structured.…

This document is a review of research on the subject of innovation diffusion and planned change, organized according to a theoretical model. The organizational scheme used is derived from Bhola's Configurational, Linkages, Environmental, and Resources (CLER) model of planned change. Conventional reviews of research identify accomplishments in…

This is the third report on the use of a technical classification assessment center (TCAC) for evaluating general detail (GENDET) personnel in the Navy. The first two reports described the development of the TCAC and the validation of the TCAC against supervisors' ratings of job performance for a small exploratory sample. This report presents the…

The third of 16 booklets designed for use in an Open University course on special education in the United Kingdom, this guide introduces key issues in the course. The variety of handicapping conditions is examined, and age and sex factors in special education are considered. Effects of the environment and the special educational system are also…

A study undertaken to find a satisfactory system of classifying and organizing materials for college or university learning assistance centers discovered that little information had been published. Further investigation revealed that the two major systems used in libraries, the Library of Congress (LC) and Dewey Decimal Systems, were found to be…

A probabilistic approach is introduced to classify and diagnose erroneous rules of operation resulting from a variety of misconceptions ("bugs") in a procedural domain of arithmetic. The model is contrasted with the deterministic approach which has commonly been used in the field of artificial intelligence, and the advantage of treating the…

Pure research in school law is not possible, since the researcher must rely on inquiry that can be verified by experience and observation in the field. The studies produced in the past year tend to fall into the following classes: compliance, accountability, impact, cost-effectiveness, Supreme Court decisions, and the process by which minority law…

Two studies compared the effects of spontaneous and controlled imagery on reality monitoring decisions. Reality monitoring refers to the decision processes involved in discriminating perceptual memories from imaginal ones. In Experiment 1, 6-year-olds and adults were shown pictures and words and they responded to one of two questions: (1)…
