Recent years have seen increasing interest in narrative-centered learning environments. However, the same qualities that make them engaging can also introduce seductive details that invite off-task behavior. This paper examines offtask behavior in the CRYSTAL ISLAND narrative-centered learning environment. Results from an empirical study examining the relationships between student test performa...

The purpose of this study was to identify factors’ direct and indirect influence on learning outcome and to examine relationship among learning outcomes. In this study, all independent variables were categorized into four main factors and under these factors, 16 subfactors were grouped. Regression and path analysis between these factors and three aspects of learning outcome (participation, sati...

C policy decisions are necessarily sequential decisions over time under uncertainty, given the magnitude of uncertainty in both economic and scientific processes, the decades-to-centuries time scale of the phenomenon, and the ability to reduce uncertainty and revise decisions along the way. Thus, an appropriate choice of analytical method is decision analysis. However, applying decision analysi...

This paper proposes a new method to solve fuzzy critical path problems for a project network with activity times being normalised trapezoidal fuzzy numbers. is solved successfully to demonstrate the validity of the proposed approach.

We consider the first-crossing-time problem through a constant boundary for a Wiener process perturbed by random jumps driven by a counting process. On the base of a sample-path analysis of the jump-diffusion process we obtain explicit lower bounds for the first-crossing-time density and for the first-crossing-time distribution function. In the case of the distribution function, the bound is im...

This study examined the motivation of young people in internet gaming using the dualistic model of passion. Path analysis was used to examine the relationships between the two types of passion: obsessive and harmonious passion, behavioral regulations, and flow. A total of 1074 male secondary school students from Singapore took part in the study. The results of the path analysis showed that exte...

The study empirically tested a research model for identifying the linkages among IT management mechanism, IT application level and IT application innovation level, based on a sample of 530 manufacturing enterprises in Jiangsu Province, China. Results indicated that IT management mechanism had significant and positive influences on IT application level and IT application innovation level. Meanwh...
