In free recall learning, taxonomic organization has been studied almost to the exclusion of alternative types of organization. Consequently, little is known about how learning and memory are affected by alternative types of organizations. The present experiments explored the differential effects of two kinds of organization on free recall…

THE RELATIONSHIPS BETWEEN SCHOOL GENERATED ANXIETY AND VARIOUS INDICES OF SCHOOL ACHIEVEMENT, CREATIVITY, AGE, AND IQ, ARE INVESTIGATED. A 160 ITEM, MULTIPLE-CHOICE, MULTI-SCALE, SCHOOL ANXIETY QUESTIONNAIRE WAS ADMINISTERED TO 56 FOURTH, FIFTH, AND SIXTH GRADE CHILDREN WITH A MEAN STANFORD BINET IQ OF 126 FROM AN UPPER MIDDLE CLASS COMMUNITY.…

An empirical assesssment of the space distortion properties of two prototypic hierarchical clustering procedures is given in terms of an occupancy model developed from combinatorics. Using one simple example, the single-link and complete-link clustering strategies now in common use in the behavioral sciences are empirically shown to be space…

A pattern-analytical technique, Similar Response Analysis (SRA), was developed, validated with contrived data, verified using previously reported data based on other pattern-analytical methods, and used successfully with "real" data. This technique orders subjects on the basis of the similarity of responses of adjacent individuals, not…

The Claremont Colleges started the first US cluster experiment in 1925. Through the cluster concept, the personal values of the small college have been preserved while it secured facilities of the university. What is not known is whether educational resources have been enriched at a faster rate than the rise in unit cost. The purpose of this study…

A retrieval system is considered in which document descriptions are stored and accessed in groups called clusters. All items in a cluster meet common similarity criteria and are represented by a composite entity called a profile. In large collections, profiles themselves are clustered and additional levels of profiles are generated. This entire…

The effects of category size and instruction to cluster on the free-recall learning of 112 nonretarded (mean age 7 years) and retarded children (mean age 10 years) were assessed. (Author)

The theory of fuzzy sets is used to provide a rigorous formulation of the problem of associative retrieval. This formulation suggests the idea of using fuzzy clustering to organize data for retrieval. (Author)

Discusses the use of research clusters at the University of Michigan School of Nursing to allow new faculty and graduate and undergraduate students to participate in research projects headed by experienced researchers, as well as to make good use of resources. Covers negotiation of a cluster arrangement, selection of cluster team members,…

Describes a Cluster Plus plan that groups middle school students into two clusters on each grade level according to ability. This arrangement retains vertical organization into core curriculum areas (mathematics, social studies, English, and science), while allowing flexible regrouping through horizontal team teaching. (MLH)

Describes a cluster-based information retrieval procedure that can significantly reduce the computational requirements of the single linkage method, while still maintaining the retrieval effectiveness of the resulting classifications. Use of nearest neighbors, experimental details, and results and conclusions are highlighted. Fourteen references…

Cluster evaluations have been defined as involving multiple sites, focusing on longer term projects, involving substantially different approaches to similar problems, and improving the social condition. Cluster evaluation is illustrated through the description of an initiative funded by the W. K. Kellogg Foundation called the Leadership for…
