Character education specialists seem to know it when they see it, but what it means to call something a character education program remains unclear. One possible source for this uncertainty is the manner in which character education has been defined. By identifying certain features as necessary, existing definitions fail to encompass the universe…

The Reduced Reparameterized Unified Model (Reduced RUM) is a diagnostic classification model for educational assessment that has received considerable attention among psychometricians. However, the computational options for researchers and practitioners who wish to use the Reduced RUM in their work, but do not feel comfortable writing their own…

This article challenges the idea that mixed methods research (MMR) constitutes a coherent research paradigm and explores how different research paradigms exist within MMR. Tracing paradigmatic differences at the level of methods, ontology, and epistemology, two MMR strategies are discussed: nested analysis, recently presented by the American…

Hierarchical classes models are models for "N"-way "N"-mode data that represent the association among the "N" modes and simultaneously yield, for each mode, a hierarchical classification of its elements. In this paper we present a stochastic extension of the hierarchical classes model for two-way two-mode binary data. In line with the original…

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)…

Infants exposed to a set of artificially-created face stimuli having distinct mean and modal prototypes showed a pattern of behavior predicted by category abstraction models. Infants appeared to abstract, at the time of learning, a feature-count summary of the category displayed. (Author/RH)

Structural models and classes of variables used in parent/child research are identified, and their implications are briefly discussed. The five types of research models appraised are noninteractive, unidirectional, bidirectional, family network, and sociopolitical. It is asserted that, taken together, the typology of models provides a system by…

Presents a model which integrates design and hardware attributes for both videotape and videodisc technologies and incorporates a wider range of equipment and presentation/testing strategies than taxonomies dealing with hardware only. Model is designed to aid potential designers/users in categorizing and selecting appropriate hardware/software…

Proposes that the development of document-retrieval systems can benefit from the incorporation of conceptual modeling techniques, specifically classification, aggregation, and generalization. An array model is presented which has been designed especially for document retrieval. (Author/EM)

Proposes scientific theory of the subject matter of library and information science and how it can be organized in terms of the function of documents and their basic use. A hierarchy of classes of documents is described including one, several, or all of the following: information, creativity, understanding, and explanation. (Author/EM)

Purpose: The purpose of this paper is to outline a three-stage process for engaging with students to develop school level indicators of health in sequential class groups students first generated, then categorised indicators and finally developed schematic representations of their analyses. There is a political and practical need to develop…

A taxonomy of computer-based speech training systems is presented, based on the physical source of feedback, standards of evaluation, level and type of detail on which feedback is based, and the form and instructional context of feedback. Reasons for selecting a particular approach are discussed in relation to existing systems. (Author/JDD)

This article describes the strengths and weaknesses of different models of classification (primarily monothetic and polythetic) and then focuses on cluster analysis as a method of pursuing a polythetic model. Design features that need to be incorporated in a cluster analytic study are discussed in relation to theory formulation, internal validity,…

Reviews the problems of classifying gaming techniques and suggests a heuristic approach as one solution. Definitions of simulation, models, role, and game and play are discussed to help develop a classification based on a technique called gaming simulation. (Author/LRW)

Delineates various levels of theory with implications for research in library and information science. Based upon a review of literature on theory building and research methods in the social sciences, a model is proposed which displays a taxonomy of theory in hierarchical form. (EM)
