Because of its hierarchical notation, the Dewey Decimal Classification is advantageous for machine searching. However, the increased volume of topics in recent years has made recoding in the system necessary. Education, for example, is a rapidly changing field, and the Dewey Decimal Classification system has not kept pace. As a result subject…

In Edition 18 of the Dewey Decimal Classification system an effort was made to keep the changes to a minimum without overly compromising the updating of the system. However, all the changes made were not caused by new knowledge; many were for structural reasons. (17 references) (Author/SJ)

The National Child Count of Children and Youth who are Deaf-Blind is the first and longest running registry and knowledge base of children who are deaf-blind in the world. It has been collaboratively designed, implemented and revised to serve as the common vehicle to meet federal grant requirements for both the State/Multi-State and National…

Rater behavior in essay grading can be viewed as a signal-detection task, in that raters attempt to discriminate between latent classes of essays, with the latent classes being defined by a scoring rubric. The present report examines basic aspects of an approach to constructed-response (CR) scoring via a latent-class signal-detection model. The…

While this Report is presented to the Library of Congress, it situates recommendations to the Library in the broader context of the environment in which the Library does and could function. Thus, the Report discusses and makes recommendations not only to the Library, but also to other current and potential participants in this environment. The…

The purpose of the current study was to assess whether children would categorize pictures when taught the relevant listener and speaker behaviors separately. A category-sort test was used to assess emergent conditional relations. Category-sort trials consisted of looking at (Test 1) or tacting/labeling (Test 2) a sample stimulus and selecting the…

Purpose: Recently, classification of Arabic documents is a real problem for juridical centers. In this case, some of the Lebanese official journal documents are classified, and the center has to classify new documents based on these documents. This paper aims to study and explain the useful application of supervised learning method on Arabic texts…

In this paper, I discuss different types of models in science education and applications of them in learning and teaching science, in particular physics. Based on the literature, I categorize models as conceptual and mental models according to their characteristics. In addition to these models, there is another model called "physics model" by the…

We contend that previous work on children's identification with social groups has looked at the mere categorization of the self in group terms and not subjective identification properly conceived. Drawing upon self-categorization theory, the present research operationalizes identification as self-stereotyping (i.e. the ability to conceive of the…

In psychological research, one often aims at explaining individual differences in S-R profiles, that is, individual differences in the responses (R) with which people react to specific stimuli (S). To this end, researchers often postulate an underlying sequential process, which boils down to the specification of a set of mediating variables (M)…

In auditory warning design the idea of the strength of the association between sound and referent has been pivotal. Research has proceeded via constructing classification systems of signal-referent associations and then testing predictions about ease of learning of different levels of signal-referent relation strength across and within different…

This study empirically evaluated a classification schema based on symbolic communication level use with students with significant cognitive disabilities. Ninety-five teachers of students with significant disabilities rated students' level of performance on 10 academic tasks. Cluster analysis suggested a range of two to four clusters solutions.…

A critical issue in perception is the manner in which top-down expectancies guide lower level perceptual processes. In speech, a common paradigm is to construct continua ranging between two phonetic endpoints and to determine how higher level lexical context influences the perceived boundary. We applied this approach to music, presenting…

Three experiments were aimed at verifying whether the modality of interaction with objects and the goals defined by the task influences the weight of the properties used for categorization. In Experiment 1 we used everyday objects (cups and glasses). In order to exclude that the results depended on pre-stored categorical knowledge and to assess…

The goal of the current study was to examine whether explaining to another person improves learning and transfer. In the study, 4- and 5-year-olds (N=54) solved multiple classification problems, received accuracy feedback, and were prompted to explain the correct solutions to their moms, to explain the correct solutions to themselves, or to repeat…
