Children with mental retardation have pronounced difficulties in using cognitive strategies and comprehending abstract concepts--among them, the concept of sequential time (Van-Handel, Swaab, De-Vries, & Jongmans, 2007). The perception of sequential time is generally tested by using scenarios presenting a continuum of actions. The goal of this…

This paper outlines and analyses some key design issues we encountered in the process of creating an online role-play simulation (RPS) for a course targeting personnel involved in crisis management. Titled "Black Blizzard" the RPS aims to enable an exploration of typical issues and problems that arise in cross and multi-cultural international…

In this work we present a case example of the use of virtual reality exposure for the treatment of panic disorder with agoraphobia. The assessment protocol and procedure (including a baseline period) and the cognitive-behavioral treatment program are described. The clinical measures were categorized into target behaviors, panic and agoraphobia…

During the past two decades, the popularity of computer and video games has prompted games to become a source of study for educational researchers and instructional designers investigating how various aspects of game design might be appropriated, borrowed, and re-purposed for the design of educational materials. The purpose of this paper is to…

Cross-validation, an economical method for assessing whether sample results will generalize, is discussed in this paper. Cross-validation is an invariance technique that uses two subsets of the data sample to derive discriminant function coefficients. The two sets of coefficients are then used with each data subset to derive discriminant function…

Describes the development of two interactive computer simulations which were fully integrated with other course materials. The simulations illustrate the effects of various real and monetary "demand shocks" on aggregate income, interest rates, and components of spending and economic output. Includes an evaluation of the simulations'…

Computer sampling from a multivariate normal spherical population was used to evaluate Type I error rates for a test of P = I based on Fisher's tanh(sup minus 1) variance stabilizing transformation of the correlation coefficient. (Author/TJH)

Reviews "The U.S. Constitution Then and Now," a two-unit program using the integrated database and word processing capabilities of AppleWorks. For grades 7-12, the units simulate the constitutional convention and the principles of free speech and privacy. Concludes that with adequate time, the program can provide a potentially powerful…

Results of the two surveys (combined n = 145) show that historians are using computers for word processing, research, and teaching support. Only a third of the respondents indicated they were using computers in the classroom, however. The most frequently reported classroom uses were student projects, simulations, and tutorials. (JDH)

Favorably reviews "The Other Side," a global conflict resolution simulation available for high school social studies classes. Maintains that this program is well worth the time and effort required to integrate it into the study of modern history and international relations. (JDH)

Describes a scheme for the mechanization of fixed-wing, lateral/directional dynamics as demonstrated on the EAI 580 analog/hybrid system. A review of the complete six degrees of freedom program is included, along with useful guidelines of aircraft simulation in the engineering laboratory. (Author/JN)

The ANDS (A Natural Deduction System) model, described in this article, is a psychological theory of propositional reasoning that makes explicit assumptions about memory and control in deduction. A computer simulation of the ANDS model yields proofs similar to those of untrained subjects. (Author/BW)

A computer simulation was designed to expose special educators to some consulting situations. The Mastery Test was given to 19 special educators before and after they completed the simulation. Results indicated that the simulation enabled Ss to choose strategies significantly more like those of expert consulting teachers. (Author/CL)

A computer-based strategy for illustrating the central limit theorem is described which introduces students to the important concept of a simulation model. The computer program is included. (MNS)

This study used computer simulation to provide information on the percentage of students with learning disabilities expected to be identified under different aptitude-achievement discrepancy eligibility models and criteria and to demonstrate the consequential effects in terms of the extent to which the different models identify students of…
