Historical time and chronological sequence are usually conveyed to pupils via the presentation of semantic information on printed worksheets, events being rote-memorised according to date. We explored the use of virtual environments in which successive historical events were depicted as "places" in time-space, encountered sequentially in…

The National Computing Centre (NCC) has developed an interactive video training system for the Scottish Police College to help train police supervisory officers in crowd control at major spectator events, such as football matches. This approach involves technology-enhanced training in a group-learning environment, and may have significant impact…

This study explored whether students benefited from an immersive panoramic display while studying subject matter that is visually complex and information-rich. Specifically, middle-school students learned about ancient Egyptian art and society using an educational learning game, "Gates of Horus," which is based on a simplified three…

The model of learning best suited to the future may be one which sees learning as the process of managing the different kinds of participation an individual might have in complex social systems. Learning capability and engagement is thus dependent on the relationship between an individual identity and social systems. We report on the incorporation…

Used Johnson's transformation (N. Johnson, 1978) with approximate test statistics to test the homogeneity of simple linear regression slopes in the presence of nonnormality and Type I, Type II or complete heteroscedasticity. Computer simulations show that the proposed techniques can control Type I error under various circumstances. (SLD)

Used computer simulation methods to examine the sensitivity of model fit criteria to misspecification of the first-level error structure in two-level models of change and to examine the impact of misspecification estimates on the variance parameters, estimates of the fixed effects, and tests of the fixed effects. Discusses problems caused by…

Describes a cost-effective way to create an effective simulation for students that teaches them how personal computers are used in the workplace. (JOW)

A computer-assisted, K-fold cross-validation technique is discussed in the framework of canonical correlation analysis of randomly generated data sets. Analysis results suggest that this technique can effectively reduce the contamination of canonical variates and canonical correlations by sample-specific variance components. (Author/SLD)

Develops a cultural transmission model with the following variables: worker entry and exit rate, organization growth rate, recruiting selectivity, socialization intensity, and the rate that socialization decays if not reinforced. A computer simulation of the model found that cultural systems in organizations are highly robust and reach equilibrium…

Describes SimSum (Simulation of Summarizing), which simulates 20 real-world working steps of expert summarizers. Presents an empirically founded cognitive model of summarizing and demonstrates that human summarization strategies can be simulated. Discusses current research in automatic summarization, summarizing in the World Wide Web, and…

Computer simulations used to compare the Mahalanobis distance procedure with the Andrews-Pregibon statistic for identifying multivariate outliers result in the conclusion that the choice of procedure is not critical, since both identified valid data points as outliers. Results with false outliers as the dependent variable suggest the importance of…

Computer simulation indicated that reliability increased with the degree of similarity between underlying and observed distributions when the observed categorical distribution was deliberately constructed to match the shape of the underlying distribution of the trait being measured. Reliability also increased with correlation among variables and…

Previous computer conferencing research has been concerned with the organizational, technical, social, and motivational factors that support and sustain online interaction. This article studies online interaction from a different perspective. Rather than analyze the processes that sustain discourse, the following research examines how and why…

How do communities establish shared communication systems? The Common Knowledge view assumes that symbolic conventions develop through the accumulation of common knowledge regarding communication practices among the members of a community. In contrast with this view, it is proposed that coordinated communication emerges a by-product of local…

The purpose of this study was to determine the most suitable ICT-based education and define the most suitable e-content creation tools for quantitative courses in the IT-management Masters program. ICT-based tools and technologies are divided in to three categories: the creation of e-content, the offering of e-content, and access to e-content. In…
