This study investigated how individuals' construction of explanations--a way of ascertaining how well an individual understands a concept--develops from an interactive simulation. Specifically, the purpose was to investigate the effect of interactive computer simulations or science textbook assignments on the nature and quality of postgraduate…

Simulations can often be used to internationalize a course and even a curriculum. For faculty that teach international and comparative courses, simulations can often provide students with an opportunity to see beyond their own country. In developing a course on political revolutions, I created a simulation in which students role-played either a…

This paper presents a web-based interactive teaching package that provides a comprehensive and conducive yet dynamic and interactive environment for a module on automated machine tools in the Manufacturing Division at the National University of Singapore. The use of Internet technologies in this teaching tool makes it possible to conjure…

While advances in technology have enhanced the quality and variety of visual presentations in teaching, most instructors find themselves teaching to a generation of students who are difficult to dazzle. Although the innovative use of technology in and outside of the classroom is a challenge, selecting practices that optimize technology as a tool…

The emergence of human communication systems is typically investigated via 2 approaches with complementary strengths and weaknesses: naturalistic studies and computer simulations. This study was conducted with a method that combines these approaches. Pairs of participants played video games requiring communication. Members of a pair were…

This article describes the instructional design theoretical foundation of a desktop virtual reality-based learning environment aimed at complementing the current novice driver education system in Malaysia. It provides an elaboration of how various components of the learning environment are designed to support this theoretical underpinning that…

Going on an expedition enables teachers to become better scientists and researchers and, thus, better classroom instructors. Teachers have the opportunities to go on exotic field trips around the world as amateur research assistants, do hands on research in their own backyards, or vicariously experience another scientist?s work via the Internet. A…

The "Mozart effect" refers to an increase in spatial reasoning performance following exposure to music composed by Mozart. Empirical tests of the effect have resulted in an inconsistent pattern of findings with some studies producing the effect and others failing to do so. The majority of the investigations have relied on paper-and-pencil tests.…

This study examined the effect of scaffolding students who learned by designing assignments for a computer simulation on the physics topic of alternating circuits. We compared the students' assignments and the knowledge acquired in a scaffolded group (N = 23) and a non-scaffolded group (N = 19). The scaffold consisted of a Design Sheet that guided…

A central issue in bilingual research concerns the extent to which linguistic representations in the two languages are processed independently of each other. This paper reports the results of an empirical study and a model stimulation, which provide evidence for the interactive view, which holds that processing is not independent. Specifically, a…

The application of the technology acceptance model to a merchandising course teaching industry software was evaluated. Based on technology acceptance research, industry software was presented emphasizing ease-of-use and usefulness. The final course project gave students a quasi real-life experience of combining merchandising skills with the…

Sensory or input factors can influence the strength of interference in the classic Stroop color-word task. Specifically, in a single-trial computerized version of the Stroop task, when color-word pairs were incongruent, opponent color pairs (e.g., the word BLUE in yellow) showed reduced Stroop interference compared with nonopponent color pairs…

Attention and working memory limitations set strict limits on visual representations, yet researchers have little appreciation of how these limits constrain the acquisition of information in ongoing visually guided behavior. Subjects performed a brick sorting task in a virtual environment. A change was made to 1 of the features of the brick being…

The primary purpose of this research is to examine the impact of estimation methods, actual latent trait distributions, and item pool characteristics on the performance of a simulated computerized adaptive testing (CAT) system. In this study, three estimation procedures are compared for accuracy of estimation: maximum likelihood estimation (MLE),…

A program evaluation was completed for a Virtual Reality (VR) pilot project intended to aid deaf children in learning various life skills which they may be at risk of not adequately learning. Such skills include crossing the street safely, exiting a building during a fire drill, and avoiding situations in which strangers may harm them. The VR was…
