Describes the Dewey Online Retrieval System (DORS), which was developed at the University of California, Los Angeles (UCLA), to experiment with classification-based search strategies in online catalogs. Classification structures in automated information retrieval are discussed; and specifications for a classification retrieval interface are…

The effectiveness of simultaneous and delayed video modeling when used by three middle-school students with moderate intellectual disabilities was examined. Alternating between modeling systems, students were taught to use the public library computer to locate specific book call numbers and use the Dewey Decimal Classification System to locate…

Structural models and classes of variables used in parent/child research are identified, and their implications are briefly discussed. The five types of research models appraised are noninteractive, unidirectional, bidirectional, family network, and sociopolitical. It is asserted that, taken together, the typology of models provides a system by…

A sequential testing model is proposed which employs discriminant functions to classify examinees into groups which could correspond to instructional treatments. A termination rule based on the computed posterior probability of group membership is suggested. (Author)

Article suggests a practical research style which makes use of the tacit know how of typographers and designers. The idea is to preface any testing activities with critical and creative activities. This leads to a three-part cyclical model: criticism, alternatives and tests. (Author)

THIS NOTE IS CONCERNED WITH IDEAS AND PROBLEMS INVOLVED IN CROSS-CLASSIFICATION OF OBSERVATIONS ON A GIVEN POPULATION, ESPECIALLY TWO-DIMENSIONAL CROSS-CLASSIFICATIONS. MAIN OBJECTIVES OF THE NOTE INCLUDE--(1) ESTABLISHMENT OF A CONCEPTUAL FRAMEWORK FOR CHARACTERIZATION AND COMPARISON OF CROSS-CLASSIFICATIONS, (2) DISCUSSION OF EXISTING METHODS…

The author's purpose is to identify, compare, and evaluate the legal basis for educational systems in five Scandanavian countries. For identifying purposes, he groups educational data for each country into six categories: status, pressure, response, evaluation, administration system, and school system. He then provides, in the major portion of the…

Graphical methods for evaluating the fit of Johnson's hierarchical clustering schemes are presented together with an example. These evaluation methods examine the extent to which the clustering algorithm can minimize the overlap of the distributions of intracluster and intercluster distances. (Author)

Presents a model which integrates design and hardware attributes for both videotape and videodisc technologies and incorporates a wider range of equipment and presentation/testing strategies than taxonomies dealing with hardware only. Model is designed to aid potential designers/users in categorizing and selecting appropriate hardware/software…

Investigated a category system of emotion words used in training beginning counselors to respond appropriately to client emotions. Experienced counselors, counselors in training, and noncounselors performed a free sort of 45 emotion words. The categories used by each subject group were more similar to each other than to the hypothesized…

This paper discusses a well-known problem of stage categorization within Kohlberg's theory of moral stages (L. Kohlberg, 1973), that of "Stage 4 1/2." Some subjects previously scored at stage 4 in Kohlberg's framework took on some characteristics of stage 2 reasoning, which suggested the possibility of regression. To reconcile this…

The causal model approach used in this study tested the cumulative hierarchical structure of the six major taxonomic levels of Bloom's Taxonomy by measuring the strengths of the linear relationships ( links'') between levels. (Editor)

Discussed is a taxonomy of intellectual abilities, the structure of intellect model, which presents a multivariate view of intelligence having both operational and informational dimensions. (GW)
