This article discusses replication sampling variance estimation techniques that are often applied in analyses using data from complex sampling designs: jackknife repeated replication, balanced repeated replication, and bootstrapping. These techniques are used with traditional analyses such as regression, but are currently not used with structural…

This study is part of an ongoing attempt to develop a usable and valid scale for assessing the flow experience in educational games. The purpose of the paper is to operationalize the dimensions of flow experience in an educational game context and to test a constructed GameFlow questionnaire. Furthermore, the study strives to validate flow…

Perception is influenced by the perceiver's ability to perform intended actions. For example, when people intend to reach with a tool to targets that are just beyond arm's reach, the targets look closer than when they intend to reach without the tool (J. K. Witt, D. R. Proffitt, & W. Epstein, 2005). This is one of several examples demonstrating…

A robust finding in imitation literature is that people perform their actions more readily if they are congruent with the behavior of another person. These action congruency effects are typically explained by the idea that the observation of someone else acting automatically activates our motor system in a directly matching way. In the present…

This article illustrates the concept of statistical independence using the example of slot machines that may be played on multiple lines.

At Portledge School in Locust Valley, New York, ninth graders in their upper school study art history for one semester. The visual arts department has created a vigorous new syllabus culminating in an hour-long mock art auction. The department selects several art movements (e.g., Post-Impressionism, Cubism, Abstract Expressionism, Social Realism,…

A variance-to-range ratio variable weighting procedure is proposed. We show how this weighting method is theoretically grounded in the inherent variability found in data exhibiting cluster structure. In addition, a variable selection procedure is proposed to operate in conjunction with the variable weighting technique. The performances of these…

The research literature on gambling behavior indicates that American Indians (AIs) suffer from pathological gambling at a greater rate than the majority population. The literature also suggests that dispositional factors, such as sensation seeking, can influence gambling. However, situational factors, such as the payback percentage of a slot…

Two types of answer-copying statistics for detecting copiers in small-scale examinations are proposed. One statistic identifies the "copier-source" pair, and the other in addition suggests who is copier and who is source. Both types of statistics can be used when the examination has alternate test forms. A simulation study shows that the…

This study sought to develop meaningful and engaging virtual cyberbullying scenarios in digital environments that reflect the educational needs of today's adolescents. In order to inform and script these scenarios, a threestage study was implemented with middle schools. This paper describes how data collected in each stage informed the…

The purpose of these modules is to provide an introduction to the world of probability and statistics to accelerated mathematics students at the high school level. The materials are centered on the fictional town of Happy Shores, a coastal community which is at risk for hurricanes. Actuaries at an insurance company figure out the risks and…

The "Technology Outlook for STEM+ Education 2012-2017" reflects a collaborative effort between the New Media Consortium (NMC), the Centro Superior para la Enseñanza Virtual (CSEV), Departamento de Ingeniería Eléctrica, Electrónica y de Control at the Universidad Nacional de Educación a Distancia (UNED), and the Institute of Electrical…

The higher education system in Taiwan has increasingly adopted business simulation games (BSGs) in recent years. Previous BSG benefit research has shifted focus from learning performance to motivation due to mixed results. One recent study empirically investigated student perceptions on the continued use of BSGs; however, the counterpart of higher…

Purpose: Teaching advanced technical concepts in a computer science program to students of different technical backgrounds presents many challenges. The purpose of this paper is to present a detailed experimental pedagogy in teaching advanced computer science topics, such as computer networking, telecommunications and data structures using…

To strengthen the motivation of learners, the professional training sector is focusing more and more on game-based learning. In this context, the authors have become interested in the design of Learning Role-Play Game (LRPG) scenarios. The aim of this article is to improve the designers' confidence in the validity of the game-based learning…
