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…

This study was designed to derive the distribution of a test statistic based on normal probability plots. The first purpose was to provide an empirical derivation of the critical values for the Line Test (LT) with an extensive computer simulation. The goal was to develop a test that is sensitive to a wide range of alternative distributions,…

Information based item selection methods in computerized adaptive tests (CATs) tend to choose the item that provides maximum information at an examinee's estimated trait level. As a result, these methods can yield extremely skewed item exposure distributions in which items with high "a" values may be overexposed, while those with low…

The purpose of this study was to compare a proposed revised a-stratified, or alpha-stratified, USTR method of test item selection with the original alpha-stratified multistage computerized adaptive testing approach (STR) and the use of maximum Fisher information (FSH) with respect to test efficiency and item pool usage using simulated computerized…

The generalized graded unfolding model (GGUM) (J. Roberts, J. Donoghue, and J. Laughlin, 1998) is an item response theory model designed to analyze binary or graded responses that are based on a proximity relation. The purpose of this study was to assess conditions under which item parameter estimation accuracy increases or decreases, with special…

In the exercise the task is to build a hydro electric tower. The students have responsibilities ranging from planning and objective setting to ordering materials and actual assembly. (MS)

Describes in detail communication games used with student teachers to make them more able and sensitive in classroom settings. (JA)

Simulation games are currently being used to teach high school students how to forecast the weather. The students are cast in the roles of forecasters given meteorological information to predict the weather and, in addition, how it will affect the lifestyles of a particular area. (DS)

This simulation study determined whether the value positions taken by 3 college constituency groups (faculty, students, and community boards) on problems in curriculum, student affairs, and personnel influenced decisions made by administration groups. (Author)

Models of four programs for individual progress through basic learning in groups to a preparation for entry into employment are outlined. (MU)

The author's eight graded simulations are designed to give practice in communication skills--discussing, organizing, interviewing, assessing materials, presenting a case and speaking in public,'--all on the level of adult responsibility. (Author)
