In incorporating technology in science education, some have expressed concern that the value added by technology is primarily due to the novelty or excitement about using the devices, resulting in no lasting effect on student motivation or learning in science. This research addresses this concern through evaluation of student motivation during a…

In the traditional instructional method used in international trade, teachers provide knowledge to learners by lecturing using slides and setting assignments; however, these methods merely deliver international trade knowledge rather than facilitating student development of relevant skills. To solve these problems, we proposed a simulation-based…

The purpose of this study was to create a valid and reliable instrument to measure teacher perceived barriers to the adoption of games and simulations in instruction. Previous research, interviews with educators, a focus group, an expert review, and a think aloud protocol were used to design a survey instrument. After finalization, the survey was…

In the U.S., future economic viability is being challenged by an increasing inability to replace retiring engineers and scientists through the year 2020 due to declines in learner motivation and proficiency in science. The expository laboratory appears to be linked with non-engagement and is one possible contributing factor to this problem…

Helping learners to visualize the structures and dynamics of particles through the use of technology is challenging. Animations and simulations can be difficult for learners to interpret and can even lead to new misconceptions. A systematic approach to development based on the findings of cognitive science was used to design, develop, and evaluate…

Integrating Google Street View into a three-dimensional virtual environment in which users control personal avatars provides these said users with access to an innovative, interactive, and real-world context for communication and culture learning. We have selected London, a city famous for its rich historical, architectural, and artistic heritage,…

Wayfinding is a kind of spatial riddle that people encounter almost daily. Although it has been well documented that wayfinding elements--namely, environmental cues, people and time--significantly influence wayfinding, there has been little work done to examine the effectiveness of those influences. In particular, the notion of wayfindingly…

This study elaborates the Rasch differential item functioning (DIF) model formulation under the marginal maximum likelihood estimation context. Also, the Rasch DIF model performance was examined and compared with the Mantel-Haenszel (MH) procedure in small sample and short test length conditions through simulations. The theoretically known…

This study examined the impact of computer simulation and supported science learning on a teacher's understanding and conceptual knowledge of current electricity. Pre/Post tests were used to measure the teachers' concept attainment. Overall, there was a significant and large knowledge difference effect from Pre to Post test. Two interesting…

The impact of computer simulations on the performance of 65 grade 11 learners in electromagnetism in a South African high school in the Mpumalanga province is investigated. Learners did not use the simulations individually, but teachers used them as an interactive demonstration tool. Basic concepts in electromagnetism are difficult to understand…

Virtual collaborative activities have the potential to keep students engaged, create a sense of community in online courses and allow them to experience and practice virtual teamwork skills. This study presents an attempt to explore students' perceptions of online collaborative learning involving both process and product oriented activities. The…

Multinomial processing tree models are widely used in many areas of psychology. A hierarchical extension of the model class is proposed, using a multivariate normal distribution of person-level parameters with the mean and covariance matrix to be estimated from the data. The hierarchical model allows one to take variability between persons into…

High fidelity simulation has become a widespread and costly learning strategy in nursing education because it can fill the gap left by a shortage of clinical sites. In addition, high fidelity simulation is an active learning strategy that is thought to increase higher order thinking such as clinical reasoning and judgment skills in nursing…

A minicourse in critical thinking was implemented to improve student outcomes in two sessions of a senior-level business course at a Midwestern university. Statistical analyses of two quantitative assessments revealed significant improvements in critical thinking skills. Improvements in student outcomes in case studies and computerized business…

Measurement invariance is a common consideration in the evaluation of the validity and fairness of test scores when the tested population contains distinct groups of examinees, such as examinees receiving different forms of a translated test. Measurement invariance in polytomous items has traditionally been evaluated at the item-level,…
