Reports the results of a simulation-based analysis of Black and Hispanic public school teacher employment in Texas. The simulation reflects recently instituted teacher testing requirements in mathematics and language competence and projects how the program is likely to affect the racial-ethnic composition of public school teachers in Texas over…

A study was conducted to assess effectiveness of a computer simulation which exposed students to three levels of real-life research situations as laboratory experience accompanying graduate level research design course. Simulation effects on achievement, perceived research competence, interest in research, and effects of differing amounts of…

This experiment used simulated production environment to examine empirically two of five management information system design assumptions Ackoff considered erroneous: managers perform better with detailed rather than summarized reports; and managers who are satisfied with needed information perform better than those who are dissatisfied and want…

Details trends in information access, services, packaging, dissemination, and networking, service fees, archival storage devices, and electronic information packaging that could lead to complete mergers of academic libraries and computing centers with shared responsibilities. University of California at Berkeley's comprehensive strategy for…

Describes features of a second generation computer simulation offering teacher education students realistic experience in maintaining verbal dialog during spelling lessons with computer-defined pupils. Features discussed include lesson content, behavioral sensitivity, cueing during training, and post-lesson debriefing. User evaluations of the…

This paper presentation will report on how some science educators at the Science Department of The Hong Kong Institute of Education have successfully employed an array of innovative learning media such as three-dimensional (3D) and virtual reality (VR) technologies to create seven sets of resource kits, most of which are being placed on the…

The consequences in terms of misclassifications of students that would occur by replacing the constructed-response portion of the Advanced Placement (AP) examinations in economics with more multiple-choice items were studied. The 1991 AP examinations in micro- and macroeconomics were used. Computer simulation found that a small but statistically…

In its first year (1986-87), a $37.4 million Connecticut aid program has markedly reduced disparities in teacher salaries and expenditures per pupil. This paper reviews the use of school aid increases in Connecticut, describes the simulation models used, explains the models' role in targeting state aid, and outlines the legislation and its…

An interactive videodisk entitled "Motion: A Visual Database" developed at the Cambridgeshire College of Arts and Technology (CCAT) is described. Three of its 194 real experiments are discussed. (YP)

Investigates differences between high-achieving and low-achieving school-based decision groups in decision making. Decision groups (207 groups of 3 members each) used computer simulations to address problems facing principals concerning fourth grade academic achievement. Higher-achieving groups made more decisions and made a combination of related…

The effectiveness of alternative procedures to correct for rater leniency/stringency effects was studied when true scores were known. Ordinary least squares, weighted least squares, and imputation of the missing data consistently outperformed averaging the observed ratings; and the imputation technique was superior to the least squares methods.…

A conceptual approach and a set of computer simulations are presented to demonstrate that random measurement error in the pretest does not bias the estimate of the treatment effect in the regression-discontinuity design. Focus is on the case of no interaction between pretest and treatment on posttest. (SLD)

Describes "Wyzt's Playground", a fourth grade math multimedia title that emulates and simulates the real-life scenario of building a playground and supports the instruction of mathematics and measures proficiency in five NCTM (National Council of Teachers of Mathematics) standards. Explains the multimedia production process and the…

This study aims to investigate the effects of a virtual reality (VR)-based learning environment on learners with different learning styles. The findings of the aptitude-by-treatment interaction study have shown that learners benefit most from the VR (guided exploration) mode, irrespective of their learning styles. This shows that the VR-based…

While other research has begun to contribute to our understanding of how pre-college students reason about variation, little has been published regarding pre-service teachers' statistical conceptions. This paper summarizes a framework useful in examining elementary pre-service teachers' conceptions of variation, and investigates the question of…
