The Rasch item analysis model is supposed to yield norm-free estimates of ability and easiness values, but there are several possible interpretations of the nature and extent of such norm-freeness. One such interpretation was that to involve the scores of one single experimental group of testees which were embedded in four differently skewed…

This project is concerned with the development and implementation of some new statistical techniques that will facilitate a continuing input of information about the student to the instructional manager so that individualization of instruction can be managed effectively. The source of this informational input is typically a short…

The Massachusetts Institute of Technology provides a catalog of 16mm filmed and videotaped lectures and demonstrations. Each listing includes title, short description, length of presentation, catalog number, purchase and rental prices, and indications as to whether the item is film or videotape and black-and-white or color. The catalog is divided…

The use of computers in areas of testing, selection, and placement processes for those in military services' training programs are viewed in this paper. Also discussed is a review of the motivational and theoretical foundation of admissible probability testing, the role of the computer in admissible probability testing, and the authors' experience…

Most research on information utilization in judgment and decision making has followed two basic approaches: "regression" and "Bayesian." Each has characteristic tasks and characteristic information that must be processed to accomplish these tasks. There has been a tendency to work within a single approach with minimal communication between the…

This bibliography on the tools and applications of operations research, management science, industrial engineering, and systems engineering lists many entries which appeared between 1961 and 1966 in 186 periodicals and trade journals. Twenty-six texts in operations research are also listed along with an indication as to which of 37 techniques or…

In decision-theoretic psychometrics, to determine the worth of individualizing instruction, equations are developed for expressing the cost and gain for applying an instructional sequence. This report is divided into three parts: first, a logical analysis of guessing; second, the effect of guessing on the quality of personnel and counselling…

A tailored testing model employing the beta distribution, whose mean equals the difficulty of an item and whose variance is approximately equal to the sampling variance of the item difficulty, and employing conditional item difficulties, is proposed. The model provides a procedure by which a minimum number of items of a test, consisting of a set…

A series of 10 teacher-prepared Learning Activity Packages (LAPs) in advanced algebra and trigonometry, these units cover absolute value, inequalities, exponents, radicals, and complex numbers; functions; higher degree equations and the derivative; the trigonometric functions; graphs and applications of the trigonometric functions; sequences and…

Part of an international study of the nature and extent of childhood mortality in geographically, socioeconomically and culturally disparate populations, this report focuses on (1) an investigation into all deaths of children under 5 years of age, and (2) a probability sample of live children within the same northern California area during an…

An empirical model of the enrollment decision for students admitted both to Rutgers University and to at least one alternate college is described. Students base their enrollment decision on the relative quality of the schools, their own abilities and family resources, and the net costs of the schools. (Author/MLW)

A descriptive model of how people make judgments under ambiguity is proposed. Two factors are reflected in the model: (1) the amount of ambiguity, which affects the size of the simulation, and (2) one's attitudes toward ambiguity. The model is tested in four experiments using individual and group analyses. (Author/LMO)

This book shows the advantages of Rasch measurement (G. Rasch) for school district testing programs. The results of Rasch methods are contrasted with conventional statistics for assessing student responses to basic skills testing. Chapter 1 shows how the Rasch probability-based method produces measures that are more useful for students, parents,…

This document presents the application and use of mathematics learning proposed by the Arkansas curriculum frameworks for grades K-4. The standards are presented in chart form and organized into five strands: (1) number sense, properties, and operations; (2) geometry and spatial sense; (3) measurement; (4) data analysis, statistics, and…

This document presents the application and use of mathematics learning proposed by the Arkansas curriculum frameworks for grades 5-8. The standards are presented in chart form and organized into five strands: (1) number sense, properties, and operations; (2) geometry and spatial sense; (3) measurement; (4) data analysis, statistics, and…
