Increasing the correlation between the independent variable and the mediator ("a" coefficient) increases the effect size ("ab") for mediation analysis; however, increasing a by definition increases collinearity in mediation models. As a result, the standard error of product tests increase. The variance inflation caused by…

Real-world phenomena simulation models, which can be used to engage middle-school students with probability, are described. Links to R instructional material and easy-to-use code are provided to facilitate implementation in the classroom.

A slavery simulation that took place as part of a field trip for students of a Hartford junior high academy led a father to file a human rights suit against the school district, and for one official to comment that simulations of complex and tragic human phenomena have "no place in an educational system." In light of these conclusions,…

Wicked educational information systems (IS) address problems with unstable educational requirements, in educational environments that are ill-defined, where complex interactions among subcomponents of the problem and its solution exist. In this dissertation, a design science research methodology (DSRM) was used to evaluate projects that developed,…

Recent studies suggest that Second Life (SL) is a useful tool for educational purposes, specifically for the language learning. However, few studies provide data regarding the effect of SL on speaking anxiety of English as foreign language (EFL) learners. Thus, this paper aims at reviewing the studies on the role of SL as a language learning tool…

The Ed Media Center in Second Life provides multiple professional development opportunities for art educators to explore the educational potential of virtual worlds together. Since it's launch in 2009, it has hosted numerous events that address contemporary students' learning preferences and that enable artists and art educators to become…

In contrast to randomized experiments, the estimation of unbiased treatment effects from observational data requires an analysis that conditions on all confounding covariates. Conditioning on covariates can be done via standard parametric regression techniques or nonparametric matching like propensity score (PS) matching. The regression or…

Due to an increasing interest in the use of single-subject experimental designs (SSEDs), appropriate techniques are needed to analyze this type of data. The purpose of this paper proposal is to present four studies (Beretvas, Hembry, Van den Noortgate, & Ferron, 2013; Bunuan, Hembry & Beretvas, 2013; Moeyaert, Ugille, Ferron, Beretvas,…

Forensic nursing is an emerging nursing specialty recognized by the American Nursing Association. However, nurses often do not have the basic knowledge or practical competence to provide the appropriate level of forensic care. The purpose of this study was to determine if differences in knowledge or practical competence existed between students…

In this paper, the authors examine the state of the art in augmented reality (AR) for mobile learning. Previous work in the field of mobile learning has included AR as a component of a wider toolkit but little has been done to discuss the phenomenon in detail or to examine in a balanced fashion its potential for learning, identifying both positive…

Abstraction is a key concept in CS, one of the most fundamental ideas underlying CS and its practice. However, teaching this soft concept to novices is a very difficult task, as discussed by many CSE experts. This paper discusses this issue, and suggests a general framework for teaching abstraction in CS to novices, a framework that would fit into…

The tutorship program is aimed at supporting students throughout their university career and its objective is to prevent future problems of adaptation in the educational ambience as well as intervening in matters of academic achievement. At the Instituto Tecnológico de Sonora (Technological Institute of Sonora) (ITSON), the individual tutorship…

Recent research in digital game-based language learning has been encouraging, yet it would benefit from research methods that focus on the gaming processes and second-language development (Larsen-Freeman, 2015) rather than learner/player reflection or individuals' beliefs about the validity of gameplay. This has proven challenging as research…

The study presented here is interested in understanding the ways in which social interaction in technology-mediated institutional settings is constrained and afforded by what Pennycook defines as "critical moments" in the educational experience. Drawing on Social Learning Analytics and on the concepts of heteroglossia, contingency and…

In the 21st Century, Educators are called to thinking in broader terms about the purpose of technology in engaging learners to work on tasks that are meaningful to them. Through technology, as described in this paper, the researcher has attempted to broaden student engagement level by developing a more engaging online game framework. The research…
