Relationships among goal setting, monetary incentives, two indexes of motivation, and performance were examined in an experimental simulation. Results suggested that goal-setting and monetary incentives were related independently to measures of motivation and performance. Incentives, however, had no impact on whether or not subjects set…

A unified approach to model building is developed from the separate techniques of regression, simulation, and factorial design. The methodology is applied in the context of a suburban school district. (Author/LS)

This paper reviews various procedures for constructing an interval for an individual's true score given the assumption that errors of measurement are distributed as binomial. This paper also presents two general interval estimation procedures (i.e., normal approximation and endpoints conversion methods) for an individual's true scale score;…

No one has ever been able to look into the language space, nor has anyone been able to measure the phenomenon of consciousness without the interference of an observer. This article changes the situation, showing that from now on it is possible to produce measures of consciousness without the presence of classical observation devices. The…

Most large-scale testing programs facing computerized adaptive testing (CAT) must face the challenge of maintaining extensive content requirements, but content constraints in computerized adaptive testing (CAT) can compromise the precision and efficiency that could be achieved by a pure maximum information adaptive testing algorithm. This…

This paper describes the development of globalization as a theme for the pre-conferences that precede the annual AHRD conference. It presents a qualitative case study of what it was like for students from the University of Minnesota to participate in the first globalization pre-conference and examines issues related to the discontinuance of the…

Appellate court simulations, also known as "moot court" and "mock Supreme Court," are widely used in U.S. colleges and universities, especially by law schools. Undergraduate appellate simulation is less widely used and less well known. This document describes some U.S. undergraduate appellate simulation activities and focuses…

Intended for use in grades 2-6, this workbook uses an interactive simulation that teaches community cooperation skills. The unit is designed so that jobs, responsibilities, and requirements can be added or modified to provide a comfortable fit for every classroom. Students define their local community, identify local community workers, understand…

To satisfy the security requirements of computerized adaptive tests (CATs), efforts have been made to control the exposure rates of optimal items directly by incorporating statistical methods into the item selection procedure. Since differences are likely to occur between the exposure control parameter derivation stage and the operational CAT…

In computerized adaptive testing, updating item parameter estimates using adaptive testing data is often called online calibration. This study investigated how to evaluate whether the adaptive testing data used for online calibration sufficiently fit the item response model used. Three approaches were investigated, based on a Lagrange multiplier…

An empirical study of the Yen (W. Yen, 1997) analytic formula for the standard error of a percent-above-cut [SE(PAC)] was conducted. This formula was derived from variance component information gathered in the context of generalizability theory. SE(PAC)s were estimated by different methods of estimating variance components (e.g., W. Yens…

A model for simulating college and university operations, finances, program investments, and market response in terms of applicants, acceptances, and retention has been developed and implemented using the system dynamics approach. The Model for University Strategic Evaluation (MUSE) is a simulation of the total operations of the university,…

In a Monte Carlo analysis of single-subject data, Type I and Type II error rates were compared for various statistical tests of the significance of treatment effects. Data for 5,000 subjects in each of 6 treatment effect size groups were computer simulated, and 2 types of treatment effects were simulated in the dependent variable during…

The primary purpose of this study was to assess the effect of item bundling on multidimensional data. A second purpose was to compare three methods for assessing dimensionality. Eight multidimensional data sets consisting of 100 items and 1,000 examinees were simulated varying in terms of dimensionality, inter-dimensional correlation, and number…
