The purpose of this presentation is to continue the dialogue on the professional status of and the specialization within the instructional design and technology (IDT) field. This presentation highlights the similarities and differences among the various classification systems, which are used for ranking occupational fields, and discusses the most…

We consider the problem of classifying an unknown observation into one of several populations using tree-structured allocation rules. Although many parametric classification procedures are robust to certain assumption violations, there is need for discriminant procedures that can be utilized regardless of the group-conditional distributions that…

This study attempted to expand the dichotomous classification scheme typically used by researchers to describe teaching incentives and to offer administrators and teachers an "alternative" framework within which to develop incentive systems. This study is built on a previous one, but used a much larger sample (n=969). Elementary, middle,…

The Carnegie Classification of Institutions of Higher Education is the framework in which institutional diversity in United States higher education is commonly described. Developed in 1971, the Classification was designed to support research in higher education by identifying categories of colleges and universities that would be homogeneous with…

The reanalysis of data to answer the original research question with better statistical techniques or to answer new questions with old data is not uncommon in quantitative studies. Meta analysis and research syntheses have increased with the increase in research using similar statistical analyses, refinements of analytical techniques, and the…

Data from records of 99 patients were used to classify cardiac patients as to whether they were likely or unlikely to experience a subsequent morbid event after admission to a hospital. Both a linear discriminant function and a logistic regression equation were developed using a set of nine predictor variables that were chosen on the basis of…

Implicit in the work of S. Huck and H. Sandler (1979) is the idea that the concept "rival hypotheses" refers to some kind of alternative explanation. Rather than being threats to internal validity, rival hypotheses, in their view, are interpretations that differ from those of the researcher. This paper broadens the idea to include any…

This supplement has been prepared to be used with Office of Education Bulletin 1930, No. 24, which is the latest complete bulletin of accredited secondary schools in the United States. It shows under each State: First, names of schools which should be added to the corresponding list in the bulletin; next, those which should be removed whether…

The logic of different types of weighting are discussed, and experiments testing weighting schemes of these types are described. The results show that one type of weighting leads to material performance improvements in quite different collection environments. (22 references) (Author)

A cluster analysis procedure is described in which 288 journals in the disciplines of physics, chemistry and molecular biology are grouped into clusters. Tabulation of citings to and from each journal processed provides the basis for clustering. (18 references) (Author/RS)

Librarians are not professionals because they are not involved with saving lives. However, their job is to be a curator of civilization. (DH)

Groups of middle-aged and elderly women were compared on problem solving behavior. Results indicated a decline in the use of classification skills among the elderly and an inability to use constraint-seeking questions. (ST)

The relationship between learning, development and ability factors is considered. (ST)

This is the continuation of the guide to the organization of small technical libraries. (The first part appeared in the September-October Bulletin and is LI 502 590.) This part deals with general processing, the application of mechanized and other non-traditional processes, information work, the future, and includes the bibliography. (93…
