Disability simulation is an educational approach to modify attitudes and behaviors toward persons with disabilities by allowing participants to experience simulated life activities of individuals with disabilities. Despite the controversy regarding the effectiveness of disability simulations and its potential counterproductive effects, however,…

Putting an electrical circuit within an inaccessible black box and asking pupils to deduce what wiring is contained within the box based solely on the circuit's behaviour is a simple teaching idea with a long history. Problems arise when trying to build enough physical black boxes to simulate a larger number of circuits within a typical school's…

Debriefing offers an opportunity to ensure that students can master critical components of nursing that they might not otherwise learn and to remove epistemological roadblocks to knowledge acquisition. Within this study, Debriefing for Meaningful Learning (DML), a theoretically-derived, evidence based and structured debriefing method, was used to…

The goal of this paper is to promote computational thinking among mathematics, engineering, science and technology students, through hands-on computer experiments. These activities have the potential to empower students to learn, create and invent with technology, and they engage computational thinking through simulations, visualizations and data…

When a shock wave interacts with a contact discontinuity, there may appear a reflected rarefaction wave, a deflected contact discontinuity and a refracted supersonic shock. The numerical simulation of shock wave refraction at a plane contact discontinuity separating gases with different densities is performed. Euler equations describing inviscid…

The equating performance of two internal anchor test structures--miditests and minitests--is studied for four IRT equating methods using simulated data. Originally proposed by Sinharay and Holland, miditests are anchors that have the same mean difficulty as the overall test but less variance in item difficulties. Four popular IRT equating methods…

In item response theory (IRT), the invariance property states that item parameter estimates are independent of the examinee sample, and examinee ability estimates are independent of the test items. While this property has long been established and understood by the measurement community for IRT models, the same cannot be said for diagnostic…

Simulation-aided learning has capability in improving student's learning performance. However, the positive effect of simulation-aided learning still being discussed, which at times has not played the purported role expected. To address these problems, Multimedia Instructional Message (MIM) appeared to be an essential supporting tool in ensuring…

When constructing multiple test forms, the number of items and the total test difficulty are often equivalent. Not all test developers match the number of items and/or average item difficulty within subcontent areas. In this simulation study, six test forms were constructed having an equal number of items and average item difficulty overall.…

The impact of response styles such as extreme response style (ERS) on trait estimation has long been a matter of concern to researchers and practitioners. This simulation study investigated three methods that have been proposed for the correction of trait estimates for ERS effects: (a) mixed Rasch models, (b) multidimensional item response models,…

In this paper, I extend the concept of observer effect into the realm of country-level secondary data analysis. When analyzing what appear to be the same secondary data using the same methods, macro-comparative researchers arrive at different results. I argue that this is a product of idiosyncratic variation directly or indirectly produced by the…

Digital products are rapidly shaping our world into a ubiquitous computing world. Because of its unique characteristics, digital artifacts are generative and highly evolving through the recombination of existing elements as well as by the invention of new elements. In this thesis, I first propose an evolutionary view to examine how digital…

This article discusses how cultural simulations promote teacher candidate cultural competence. The case study uses intercultural communicative competence to examine written reflections and focus group interviews of 21 undergraduate teacher candidates in Hawai'i who engaged in cultural simulation visits on the island of O'ahu. Findings reveal that…

This study deals with solving the current problem of pedagogy of high school -- consolidation of theoretical and practical approaches to ensure the quality of professional training of law students. According to the author, the introduction of simulation modelling technologies in training courses allows enhancing interdisciplinarity in teaching,…

A challenge with flipped instruction is the pre-class preparation, where students independently learn fundamental content outside the classroom. For this pre-class learning, instructors typically assign videos with quizzes. However, this approach is the same for all and does not address differential needs. In a prior National Science Foundation…
