Multiple samples of university students (N = 1,537) completed the Almost Perfect Scale-Revised (APS-R; R. B. Slaney, M. Mobley, J. Trippi, J. Ashby, & D. G. Johnson, 1996). Cluster analyses, cross-validated discriminant function analyses, and receiver operating characteristic curves for sensitivity and specificity of APS-R scores were used to…

In this research project, subject terms from the Dewey Decimal Classification (DDC) Schedules and Relative Index were incorporated into an online catalog as searcher's tools for subject access, browsing, and display. Four features of the DDC were employed to help searchers browse for and match their own subject terms with the online catalog's…

To examine the link between analytic and holistic modes of processing and the amount of domain knowledge, 2 category-learning studies were conducted with 5-year-old children. In the first study, 26 kindergarten children were classified according to their verbal knowledge about plants and their familiarity with flowers. They then performed a…

Cut scores, quartile ranking, sample size, and overall classification scheme were studied as personnel selection procedures in two samples. The first was 120 simulated observations of employee scores based on actual selection procedures for applicants for administrative assistant positions. The other sample was composed of test results for 73…

Professionals responsible for educational research, evaluation, and statistics have sought to provide timely and useful information to decision makers. Regardless of the evaluation model, research design, or statistical methodology employed, informing the decision making process with quality, reliable data is a basic goal. The definition of…

In 1992, RAND received a grant from the National Science Foundation to study the technical quality of performance assessments in science and to evaluate their feasibility for use in large-scale testing programs. The specific goals of the project were to assess the reliability and validity of hands-on science testing and to investigate the cost and…

A new approach to the study of text building behavior is possible through the application of Scanator. This paper consists of a demonstration of some of its fundamental functions. These are suitable in a study of text building. The basic concepts, expressed through an analysis of a small part of an interview text, derive from a thermodynamic…

This study examined whether children (ages 6-16) diagnosed as having attention deficit disorder with hyperactivity (ADD/H) could be differentiated from those diagnosed as having attention deficit disorder without hyperactivity (ADD/WO), on an anterior-posterior gradient paradigm. It was predicted that ADD/H children (N=23) would have more deficits…

The implications of the 1994 Seels and Richey domain structure for instructional technology (IT) conceptual theory and classification systems, in general, for theory construction are explored. The historical evolution of domains in definitions of the field, the formulation of theory, the nature of taxonomies, the role of conceptual frameworks and…

This paper presents a detailed derivation of method of moments estimates used in computer programs for the four-parameter beta compound binomial strong true score model. A procedure is presented to deal with the case in which the usual method of moments estimates do not exist or result in invalid parameter estimates. The results presented…

This book contains background information and extensive appendices to be used for the purpose of enrolling in an Indian tribe. Chapter 1, "Why Enroll in an Indian Tribe?" explains that enrollment in a tribe often determines eligibility of American Indians for certain government programs (including educational programs). Chapter 2, "Who is an…

Two studies among U.S. college students (n=88 and n=329) examined the relationships between the order in which responses are offered on a questionnaire and the ranked importance of those responses. Study 1 included 36 males and 52 females, and Study 2 included 127 males and 202 females. Both studies found that approximately one-third (32 percent…

Labeling Peter Elbow an "expressivist" is an ironic reduction of his multifaceted thought to a one-dimensional term at a time when postmodernism stresses heteroglossia. This paper outlines the recent history of "expressivism" to demonstrate its curious social construction. The paper then calls for an "end of…

Using computer simulation data, the effect of a single global outlier in two-group classification analysis was explored in terms of the outcome variables of change in classification results (PCHNG), change in misclassification rate (MISDIF), and change in precision of misclassification rate estimation. The precision of misclassification rate…

Measurement of the mutual intelligibility of dialects of a language is discussed. The focus is on several theoretical constructs in measurement, illustrated with data from an earlier study of the mutual intelligibility of 17 Chinese dialects. Measurement procedures are also explained. It is proposed that mutual intelligibility is based on the…
