The Answer-Until-Correct (AUC) procedure has been proposed in order to increase the reliability of multiple-choice items. A model for examinees' behavior when they must respond to each item until they answer it correctly is presented. An expression for the reliability of AUC items, as a function of the characteristics of the item and the scoring…

Contains an update of an earlier listing of software for mathematics instruction at the college level. Topics are: advanced mathematics, algebra, calculus, differential equations, discrete mathematics, equation solving, general mathematics, geometry, linear and matrix algebra, logic, statistics and probability, and trigonometry. (PK)

Project MAP (Model Accounting Plan) is a demographic accounting model for monitoring the transitions of special education students through the school system and after graduation. MAP predicts the students' paths, considering the student's age, handicap, and instructional setting. Discussed are a pilot test and the model's potential benefits and…

Suggests a series of ratio activities that make use of a computer to produce graphical collections of objects in a grid with variable dimensions. Extends content to the areas of proportions, statistics, probability, programming, and problem solving. (PK)

Presents three traditional problems from discrete mathematics with alternative solutions and discussion of those solutions. (PK)

Data reported in this paper is part of a larger study which explored form five (14 to 16 year olds) students' ideas in probability and statistics. This paper presents and discusses the ways in which students made sense of task involving independence construct obtained from the individual interviews. The findings revealed that many of the students…

Building on previous research on the tendency in students of diverse ages to overrely on proportionality in different domains of mathematics (e.g., geometry, probability), this study shows that--when confronted with missing-value word problems--Flemish primary school pupils strongly tend to apply proportional solution strategies, also in cases…

The psychometric research done by G. Rasch between 1951 and 1959, which is explained and illustrated in this book, takes psychometrics from being purely descriptive to being a science of objective measurement. Individual centered statistics require models in which each individual is characterized separately and from which, given adequate data,…

Demonstrates a statistically valid method allowing students to explore randomization. Described are two examples: counting techniques for a small set of data and simulation for a large sample. (YP)

Explains a new way of viewing Bayes' formula. Discusses the revision factor and its interpretation. (YP)

Analyzes a sample of over 4,700 orders for library materials at the University of California, Berkeley, in terms of the probability that the material will arrive and the factors that determine arrival. Models to evaluate the book ordering process are presented, and variables that may affect arrival time are discussed. (six references) (Author/LRW)

It is proposed that clinical decision making in pharmacy should integrate principles of pharmacoepidemiology, economics, and medical decision making, and that case studies provide an opportunity to use these principles in probabilistic reasoning, thereby improving self-learning, critical thinking, and therapeutic and monitoring skills. Steps in…

Examined inconsistencies in secondary school students' reasoning about the probability concept of equally likely events. Results of two studies suggest that the number of students who understand the concept of independence is much lower than the latest National Assessment of Educational Progress results indicate. (Contains 22 references.) (MDH)

Presents two methods of calculating the expected value for a participant on the television game show "The Wheel of Fortune." The first approach involves the use of basic expected-value principles. The second approach uses those principles in addition to infinite geometric series. (MDH)

Describes how Logo computer simulations, or microworlds, were incorporated into a series of lessons on the nature of probability. Data were generated and displayed using Logo. (MKR)
