Basic mathematical concepts of Managerial Economics, a way of quantitatively analyzing and structuring the making of a business decision, are presented. Advantages and disadvantages of its use in business are discussed and several recent applications are given. (DT)

A study of probability learning using a noncontingent binary prediction situation to evaluate the effect of pretraining reinforcement schedule. (author/MB)

Task analysis, learning hierarchies, and behavioral objectives for mastery learning were used to develop elementary school curriculum materials in probability and statistics. The feasibility of the unit was measured by pre- and posttests with an instrument specifically developed for the study; analysis of data is included. (JG)

To investigate the relationship between multiple-choice and completion geometry test scores, this study used a technique for quantifying and comparing the validity of scores of different levels. (Author/DR)

Considers problem of optimal scheduling of Boolean expression (each Boolean variable represents binary outcome of program module) on single-processor system. Optimization discussed consists of finding operand arrangement that minimizes average execution costs representing consumption of resources (elapsed time, main memory, number of…

The use of prevalence data is discussed to help find the best way to separate at-risk and not-at-risk groups. Implications of the data being distributed normally are also discussed and several examples, including one with a nonnormal distribution, are given. (Author/GK)

Describes confidence testing methods (confidence weighting, probabilistic marking, multiple alternative selection) as alternative to computer-based, multiple choice tests and explains potential benefits (increased reliability, improved examinee evaluation of alternatives, extended diagnostic information and remediation prescriptions, happier…
