This paper describes the process of automatic extraction of implicit--global--data from explicit information by file inversion and threading. Each datum is the symbolic representation of a proposition, and as such has a number of movable parts corresponding to the ideal elements of the proposition represented; e.g., subject, predicate. A third…

The richness of the information available in cross-classification tables, compared to the information conveyed in the typical correlation coefficient, is emphasized in this paper. The kinds of information to be found in cross-classification tables are described, and several examples of the use of cross-classification patterns in research are…

A framework, or classification scheme, is provided for displaying the spectrum of criterion-referenced tests. This framework illustrates that no single type of test can be identified as the absolute prototype criterion-referenced test. It is shown that over the past 115 years criterion-referenced testing has grown to be a many-faceted concept, its…

TWENTY-SEVEN STUDIES ON INTERCLASS GROUPING AT THE ELEMENTARY LEVEL ARE SUMMARIZED. IT IS POINTED OUT THAT THE SUMMARY IS NEITHER EXHAUSTIVE NOR DELIBERATELY SLANTED. STUDIES POORLY DONE IN TERMS OF SAMPLE OR TREATMENT WERE NOT INCLUDED. THE STUDIES ARE GROUPED ACCORDING TO TWO QUESTIONS--(1) IS ACHIEVEMENT INCREASED BY GROUPING AND (2) ARE…

THE TRIPLE MODE TEST OF CATEGORIZATION (TMT-CAT), A COPY OF WHICH IS INCLUDED WITH THIS DOCUMENT, WAS CONSTRUCTED AND VALIDATED TO MEASURE THREE MAJOR MODES OF CATEGORIZATION POSTULATED BY VYGOTSKY. THE TMT-CAT CONTAINS 131 TEST ITEMS WHICH ARE PICTURES IN FORCED-CHOICE-PAIR COMPARISONS. THE CHILD MUST INDICATE PLACEMENT OF A STIMULUS PICTURE IN…

Between 1900 and 1905, Rudolph Focke published a series of papers on classification theory and a draft of a code for the construction of classified catalogs. His work was the direct result of the reform of librarianship during the last decades of the nineteenth century. The large number of classification systems used by German university and…

Studies of concept formation in infancy have demonstrated that certain experimental settings can elicit spontaneous behavior from infants which has been called "sorting" or "object grouping". This study pursues the issue of early sorting with infants as young as 6 months, and with a broader range of stimuli than has been used…

The investigation is part of a continuing project to find better means for studying and evaluating document representations (e.g., abstracts, indexes). The present study focused on understanding the ways individuals interpret index terms, with the goal of using the findings in improving indexing systems. Indexing systems use all-or-none bases for…

The classification may be used (1) to identify cancer research efforts supported by NCI in selected areas of research (at any general or specific level desired), (2) to store information related to cancer research and retrieve this information on request, and (3) to match interests of cancer research scientists against information in published…

An experiment is reported in which 78 subjects examined synonymic and generic-specific relationships among 513 terms compiled from subject indexes of programming textbooks and manuals. Terms were assigned in groups of 20 so that given decisions for terms could be compared for three subjects. The experiment suggested such methodological…

The measurement of affect to support the achievement or nonachievement of affective education goals is an unresolved problem for educational institutions. The paper outlines a means for both developing an affective goal structure and identifying measurable indicators of affective behavior. To achieve this, it defines and discusses concepts related…

Developed to help people in gathering, compiling, and interpreting data relating to the application of technology to instruction, this handbook provides assistance in the form of standardized terms and definitions and a structure showing the interrelationships of those terms. The handbook is organized to lead logically from an overall definition…

The fact that so many notions and principles set forth by Panizzi are still in evidence today is proof of his great contribution to present day cataloging. The comparisons made of the two sets of rules point out many contrasts and similarities. But even more significant is that, while reading the comparisons, one is constantly reminded of the…

Prepared by the Southern Rural Development Center (SRDC), this directory identifies personnel working in the area of rural development. Names, addresses, phone numbers, position titles, percentage of time devoted to Title V projects (Rural Development Act), and work classifications (research or extension) are provided for personnel residing in 13…

A schema for making possible a more systematic means of processing (reading and interpreting) the literature on reading comprehension is discussed. The system is based on classification of the literature into broad categories according to the aspects of reading comprehension which permit intelligent comparisons, contrasts, and insights. It is…
