Great educators of history were categorized on the basis of their: aims of education, fundamental ideas, and educational theories. They were classed by Ward's method of hierarchical analysis into six groupings: Socrates, Ausonius, Jerome, Abelard; Quintilian, Origen, Melanchthon, Ascham, Loyola; Alciun, Comenius; Vittorino, Basedow, Pestalozzi,…

Presents a document-clustering algorithm that uses a term frequency vector for each document in a Japanese collection to produce a hierarchy in the form of a document classification tree. Introduces an application of this algorithm to a Japanese-to-English translation-aid system. (Author/LRW)

Introduces a new approach for partitioning test items into dimensionally distinct item clusters. The core of this approach is a new item-pair conditional-covariance-based proximity measure that can be used with hierarchical cluster analysis. The procedure can correctly classify, on average, over 90% of the items for correlations as high as 0.9.…

Discusses hierarchic document clustering in information retrieval and its potential improved effectiveness over inverted file search (IFS). Describes experiments conducted to determine whether hierarchic clustering can increase the retrieval effectiveness compared to both static clustering and of conventional IFS when it is applied to search…

In a study exploring the relationship between typology and risk, we investigated the daily routines of a heterogeneous sample of young men and women from two sites who had been homeless for varying periods (N=1289). Cluster analysis yielded four groups--"Partnered", "Socially engaged", "Service connected-harm avoidant", and "Transgressive"--based…

A study with students enrolled at an urban technical college compared learning of HTML coding across three Web-based program versions. One group received examples providing factual information about the source code (Facts group). A second group was presented with a step-by-step description of the source code (Procedures group). The third group was…

The author of this article observes that sometimes educators are so overwhelmed by the needs of struggling learners that they believe they do not have time for the gifted, talented, high achieving, and high potential students. However, those students are just as desperate as any other students for good teachers to help them progress. Middle school…

Adopting a person-centered approach, we profiled 5th and 6th grade children's (152 boys and 161 girls) school-related beliefs about perceived task difficulty and agency beliefs in ability and effort. Five clusters were compared across key learning-related dimensions encompassing underlying worldviews (means--ends beliefs, normative difficulty,…

The universality of reading comprehension strategies across languages is a view generally accepted. What has not been clearly established, however, is the degree to which specific comprehension strategies are used by skilled L1 and L2 readers in the early grades. To investigate this issue, similarities and differences in the reading strategies of…

The "28th Annual Report to Congress on the Implementation of the Individuals with Disabilities Education Act, 2006" follows the 2005--i.e., the 27th annual report--in sequence. The "28th Annual Report to Congress" has two volumes. Volume 1 presents a picture of how children and students are being served under the law nationwide…

This pilot study proposes a set of analytical steps for comparing schools that participate in the National Science Foundation's Math and Science Partnership (MSP) Program and their nonparticipating peers in the same state. This pilot is part of a larger effort to evaluate the MSP Program's role in student achievement, with two companion analyses.…

A phonographic study of students' experience of oral presentations in an open learning theology programme constituted three contrasting conceptions of oral presentations--as transmission of ideas; as a test of students' understanding of what they were studying; and as a position to be argued. Each of these conceptions represented a combination of…

Frender and Doubilet suggest that Bousfield's ratio of repetitions (RR) is the best measure of clustering in free recall presently available. Conditioning only on the number of words recalled, they determine the mean of RR in the absence of clustering. In this note the null variance of RR is presented. (Author)

The Standard Occupational Classification is a new approach to classifying occupations being developed that will furnish a coding system and nomenclature to meet the varied needs of those concerned with identifying, classifying, and coding occupations. (Author/BP)

Develops and illustrates a method for clustering hierarchically the interrelationships between many persons, as represented in a matrix of a thousand by a thousand. (RC)
