The effects of a multidimensional latent trait space on estimation of item and person parameters by the computer program LOGIST are examined. Several item pools were simulated that ranged from truly unidimensional to an inconsequential general latent trait. Item pools with intermediate levels of prepotency of the general latent trait were also…

The goal of this research was to predict from a recruit's responses to the Armed Services Vocational Aptitude Battery (ASVAB) items whether the recruit would pass the Armed Forces Qualification Test (AFQT). The data consisted of the responses (correct/incorrect) of 1,020 Navy recruits to 200 items of the ASVAB together with the scores of these…

This 3-year research project, centered on the cognitive psychology of child-computer interaction, focused on the use of microcomputers for teaching specific topics in mathematics and science. In particular, issues arising from the use of computer-based simulations to promote learning (including the nature of the information displayed, the degree…

In order to evaluate standard setting procedures, apart from the more commonly applied approach of simply comparing the derived standards or failure rates across various techniques, this study investigated the errors of classification associated with the contrasting groups procedures. Monte Carlo simulations were employed to produce…

Many multidimensional item response theory (IRT) models have been proposed. A comparison is made between the so-called full information models and the models that use only pairwise information. Three multidimensional models described are: (1) the compensatory model of R. D. Bock and M. Aitken (1981) using the computer program TESTFACT; (2) a model…

The Educational Technology Center (ETC) Complex Systems Project was initiated to explore ways of using computers to help students understand systems which have often proven too complex for most high school students to understand. Preliminary work concentrated on the cognitive processes involved in modeling simple systems. This paper describes an…

A study was undertaken to develop hardware and software to help students learn the operation of real production lines and imitate them without disturbing the actual working of the production line. The study also identified major research topics according to the list of eight major technologies targeted by the Taiwanese government and considered…

This document reports the results of a study on the feasibility of training smog check mechanics in California via hands-on verification of mechanics' ability to inspect and repair vehicles. The reviews of the research literature that compare the learning effectiveness of different delivery media tend to support the position that in learning, the…

The proponents of test disclosure argue that disclosure is a matter of fairness; the opponents argue that fairness is enhanced by score equating which is dependent on test security. This research simulated disclosure on a professional licensing examination by placing response keys to selected items in some examinees' records, and comparing their…

Recent research on solving addition and subtraction word problems has resulted in the construction of theoretical models of children's problem-solving processes. Some of these models have been translated into computer programs. Characteristics and predictions of the theoretical analysis developed by Riley, Greeno, and Heller (1983) are discussed…

Defines computerized functional business games as those focusing on decision making and integration in the areas of accounting/finance, marketing, personnel/human resources, and production/operations. Nine currently available games are reviewed and evaluated in the context of a learning model. (Author/LRW)

Discussion of laboratory experiment simulation in science and engineering education focuses on the need for authoring systems that can be used to create simulations. An editor for a simulator model containing variables and mathematical equations is presented, and screen displays and data analysis are discussed. (LRW)

Multidimensional item response data were created. The strength of a general factor, the number of common factors, the distribution of items loadingon common factors, and the number of items in simulated tests were manipulated. LOGIST effectively recovered both item and trait parameters in nearly all of the experimental conditions. (Author/JAZ)

This paper presents 11 statistical procedures which test the equality of m coefficient alphas when the sample alpha coefficients are dependent. Several of the procedures are derived in detail, and numerical examples are given for two. (Author/LMO)

Links forecasting and planning with policymaking in social and societal systems and presents a planning and forecasting methods taxonomy which combines with policymaking and interactive simulation as an inquiry method for planning. A case study of university manpower development illustrating interactive simulation/gaming and its potentials for…
