Methods of probability modeling to analyze rater agreement are described, emphasizing their basic similarities and viewing them as variants of a common methodology. Statistical techniques for analyzing agreement data are described to address questions such as how many opinions are required to make a medical diagnosis with necessary accuracy. Kappa…

The seven articles in this edition show that cost-benefit analysis is emerging from the confusion of the 1980s and is probably going to become the central tool of program evaluation in the future. The modern approach involves incorporating probability distributions into the cost-benefit analysis. None of the articles are specifically…

The discrete mathematics topics of trees and computational complexity are implemented in a simple reliability program which illustrates the process advantages of the PASCAL programing language. The discussion focuses on the impact that reliability research can provide in assessment of the risks found in complex technological ventures. (Author/JJK)

Five sets of activities for students are included in this document. Each is designed for use in junior high and secondary school mathematics instruction. The first is concerned with the use of models in mathematics. The second contains a variety of activities involving polygonal numbers. The third set of activities includes a variety of games for…

This special issue demonstrates the symmetry and rigor of probabilistic conjoint measurement in practical applications in education and other human sciences. Following the opening chapter introducing the theory, other chapters focus on conjoint measurement in testing and student evaluation, standard setting, and the study of behavior and attitude.…

Five sets of activities for students are included in this document. Each is designed for use in junior high and secondary school mathematics instruction. The first "Note" concerns magic squares in which the numbers in every row, column, and diagonal add up to the same sum. An etching by Albrecht Durer is presented, with four questions followed by…

Five sets of activities for students are included in this document. Each is designed for use in junior high and secondary school mathematics instruction. The first Note concerns mathematics on postage stamps. Historical procedures and mathematicians, metric conversion, geometric ideas, and formulas are among the topics considered. Successful…

This issue of the journal contains abstracts and critical comments for 10 published reports on research in mathematics education. The reports concern children's school mobility and achievement, preservice teachers' sources of decisions, spatial visualization in boys and girls, rote versus conceptual emphases in teaching probability, using drawings…

To examine the economic efficiency of initial military specialty training, procedures were tested for estimating the effects of that training on posttraining job performance. The approach chosen was an application of human capital theory in which the costs of on-the-job training and the returns to training are measured by comparing the trainee's…
