In this article, we discuss how quantum physics and relativity can be taught in upper secondary school, in ways that promote conceptual understanding and philosophical reflections. We present the ReleQuant project, in which web-based teaching modules have been developed. The modules address competence aims in the Norwegian national curriculum for…

The goal of the dependability analysis is to predict inconsistencies and to reveal ambiguities and incompleteness in the designed learning scenario. Evaluation, in traditional learning design, is generally planned after the execution of the scenario. In mobile learning, this stage becomes too difficult and expensive to apply due to the complexity…

The stock market has a high profit and high risk features, on the stock market analysis and prediction research has been paid attention to by people. Stock price trend is a complex nonlinear function, so the price has certain predictability. This article mainly with improved BP neural network (BPNN) to set up the stock market prediction model, and…

Leung and Lewkowicz remind us that the debate over the past two decades that is most relevant to ELT (English languge teaching) pedagogy and curriculum concerns test-task authenticity. This paper first reviews how the authenticity debate in the literature of second language acquisition, pedagogy and testing has evolved. Drawing on a body of…

The objective of this study is to evaluate the potential of a game called "Star Power" to teach professional skills to mechanical engineering undergraduates. The game was conducted as an activity in a final year Professional Practice unit. A survey in the form of a questionnaire was administered to participating students in the following…

Introduced to study components of ionized gas, the mass spectrometer has evolved into a highly accurate device now used in many undergraduate and research laboratories. Unfortunately, despite their importance in the formation of future scientists, mass spectrometers remain beyond the financial reach of many high schools and colleges. As a result,…

In the modern workplace, collaboration is no longer only a face-to-face process. When working together, it is common for teams to rely on technology and operate across geographic, temporal and cultural boundaries. Most research, when looking at distributed teams, takes a uni-disciplinary perspective and fails to address the entire problem space.…

Nursing education faces many challenges such as faculty shortages, inadequate clinical site placements, the inability to accept qualified students because of limited resources, and how to effectively educate students who are tech savvy, confident, highly motivated yet have differing needs from previous generations. This study sought to explore how…

In this study, "television program simulation" which was prepared in compliance with microteaching technique and thought to be effective in environmental education is introduced. This program was tried with 31 primary education pre-service teachers in Aksaray University in environmental education courses during 2009-2010 academic year.…

Whether human evaluative conditioning can occur without contingency awareness has been the subject of an intense and ongoing debate for decades, troubled by a wide array of methodological difficulties. Following recent methodological innovations, the available evidence currently points to the conclusion that evaluative conditioning effects do not…

Rasch used a Poisson model to analyze errors and speed in reading tests. An important property of the Poisson distribution is that the mean and variance are equal. However, in social science research, it is very common for the variance to be greater than the mean (i.e., the data are overdispersed). This study embeds the Rasch model within an…

In this article, we present a perspective on the role of the hippocampal system in generalization, instantiated in a computational model called REMERGE (recurrency and episodic memory results in generalization). We expose a fundamental, but neglected, tension between prevailing computational theories that emphasize the function of the hippocampus…

"If free trade is a no-brainer, why isn't trade free?" Students often express such sentiments at the conclusion of a typical international trade course, during which they have learned that free trade is optimal, but that countries continue to restrict trade substantially. This article describes a simulation of a round of trade…

A Monte Carlo study was conducted to examine the accuracy of differential item functioning (DIF) detection using the differential functioning of items and tests (DFIT) method. Specifically, the performance of DFIT was compared using "testwide" critical values suggested by Flowers, Oshima, and Raju, based on simulations involving large numbers of…

The Graded Response Model (GRM; Samejima, "Estimation of ability using a response pattern of graded scores," Psychometric Monograph No. 17, Richmond, VA: The Psychometric Society, 1969) can be derived by assuming a linear regression of a continuous variable, Z, on the trait, [theta], to underlie the ordinal item scores (Takane & de Leeuw in…
