Investigates why children under eight years of age show categorical clustering above chance expectations in free recall, when such organization does not correlate with recall. Six-year-old children and adults were tested for memory of 24 pictures of categorizable items. Proportion of items recalled in category strings and number of strings of each…

Relative difficulty of Separate (Form S) and Grouped (Form G) True-False tests may be expected to be dependent on the ability levels of examinees. At some levels Form S should be less difficult, at others equally difficult, and at still others, more difficult, than Form G. (Author/RL)

The use of evaluations for policy and program development and change is critically reviewed. Existing conceptions of utilization are discussed and improvements in the methods of detecting use are suggested. Five clusters of variables affecting utilization are described and hypotheses about the reasons for their effects are outlined. (Author/AL)

The aim of the computerized grouping procedure was to facilitate the management of individualized programs of instruction by grouping students in accordance with a large number of teacher- and school-specified factors more efficiently than would be possible manually. (Author/IRT)

Procedures used for developing a quantified job analysis system for managerial personnel in a power utility are described. Factor analysis of questionnaires yielded 60 job dimensions which were used to define position profiles and job clusters. The usefulness of this type of information for personnel decisions is discussed. (Author/SJL)

Discusses the existence of matter in smaller groups known as clusters. Applications of the findings in scientific studies are presented as they relate to technology. (SA)

A new Minnesota school has succeeded in translating a noble, inclusive vision into reality. Asked to evaluate the school's first year, staff identified several accomplishments: presence of family-like communities of learners; focus on meeting individual special-education needs within these communities; celebration of diversity as a strength to…

Proposes and illustrates a method of identifying key words in text, and leads from this proposal to the notion of key key words (words that are key in many texts). Notes that a key key word has associates: words that are key in the same texts as a given key key word. Notes that these associates can be grouped together in clumps. (18 references)…

Results of three investigations of the development of word definitions indicated that younger childrens' definitions, including use or lack of use of superordinate categorical terms, fell short of adult informativeness, while, by age 10, children generally met such criteria in their definitions.

Cluster analysis on factor analytic symptom profiles obtained from the Achenbach Child Behavior Checklist for 204 three- to five-year-old boys including 79 autistic and autistic-like children identified an autistic group as soon as three clusters were formed. This autistic cluster was later subdivided according to presence/absence of anxiety and…

Two versions of a decision rule for determining the most appropriate number of clusters on the basis of a correlation matrix are presented, applied, and compared with three other decision rules. The new rule is efficient for determining the number of clusters on the surface level for multilevel data. (SLD)

This study with 39 secondary students with severe disabilities integrated into regular programs in either home schools or cluster programs found that the proportion of students residing outside the normal school boundaries and the percent of students classified as Severely Multiply Handicapped were both negatively associated with both in-school…
