Virtual Reality (VR) offers language learners a valuable environment for practicing language skills and other aspects essential for language development, interaction, and negotiation of meaning. For example, speaking practice in VR using avatars can reduce speaking anxiety and increase users' sense of agency. Social spaces in VR present…

Interactive simulations allow students to independently explore scientific phenomena and ideally infer the underlying principles through their exploration. Effectively using such environments is challenging for many students and therefore, adaptive guidance has the potential to improve student learning. Providing effective support is, however,…

Interactive simulations allow students to discover the underlying principles of a scientific phenomenon through their own exploration. Unfortunately, students often struggle to learn effectively in these environments. Classifying students' interaction data in the simulations based on their expected performance has the potential to enable adaptive…

Game-based learning is gaining popularity in language education. For the present study, three games were developed with a central focus on intercultural interaction to be played internationally in dyads or small groups using Video-Communication (VC) tools or a Virtual World (VW). The interactions were carried out in Spanish as a Lingua Franca (LF)…

Recent years have seen significant interest in multimodal frameworks for modeling learner engagement in educational settings. Multimodal frameworks hold particular promise for predicting visitor engagement in interactive science museum exhibits. Multimodal models often utilize video data to capture learner behavior, but video cameras are not…

Simulations that combine real world components with interactive digital media provide a rich setting for students with the potential to assist knowledge building and understanding of complex physical processes. This paper addresses the problem of modeling the effects of multiple students' simultaneous interactions on the complex and exploratory…

Virtual simulation training has gained in usage in various educational fields and offers the potential to support and reinforce learning goals when practical experience is not possible. Teaching practice experience in an English as a Foreign Language (EFL) classroom is critical, yet frequently unobtainable for students in Teaching English to…

Teaching and learning programming has presented many challenges in institutions of higher learning worldwide. Teaching and learning programming require cognitive reasoning, mainly due to the fundamental reality that the underlying concepts are complex and abstract. As a result, many institutions of higher learning are faced with low success rates…

High-tech tools can be integrated to serve a number of purposes in the mathematics classroom, with different purposes being appropriate for different learning goals. We focus specifically on the various purposes for interactive simulations (sims). This study followed three experienced middle-school mathematics teachers integrating PhET sims into…

Usually, distribution electricians are called upon to solve technical problems found in electrical substations. In this project, we apply problem-based learning to a training program for electricians, with the help of a virtual reality environment that simulates a real substation. Using this virtual substation, users may safely practice maneuvers…

Analysis of the applicability of a learning technology requires evaluating how the affordances of the technology respond to the users' needs. We examine affordances of a digital learning environment. We concentrate on organizational and socio-interactional affordances, which are based on technological affordances. The analysis shows how…

Virtual reality technology offers the promise of interaction with a computer-based environment that engages visual, auditory, and tactile perception. Three interrelated virtual reality design topics are particularly relevant to visual literacy. The first is the concept of avatars. Avatars are agents that appear in a virtual world representing the…

This paper provides an overview of a prototype simulation-centered intelligent computer-based training (CBT) system--implemented using expert system technology--which provides: (1) an environment in which trainees can learn and practice complex skills; (2) a computer-based coach or mentor to critique performance, suggest improvements, and provide…

Current omnibus procedures for the analysis of interaction effects in repeated measures designs which contain a grouping variable are known to be nonrobust to violations of multisample sphericity, particularly when group sizes are unequal. An alternative approach is to formulate a comprehensive set of contrasts on the data which probe the specific…

This study investigated the robustness of the James second-order test (James 1951; Wilcox, 1989) and the univariate F test under a two-factor fixed-effect analysis of variance (ANOVA) model in which cell variances were heterogeneous and/or distributions were nonnormal. With computer-simulated data, Type I error rates and statistical power for the…
