Many studies use instructional designs that include two or more artifacts (digital manipulatives, tables, graphs) to support students' development of reasoning about covarying quantities. While students' forms of covariational reasoning and the designs are often the focus of these studies, the way students' interactions and transitions between…

In this paper, we present the development of an investigation on the promotion of covariational reasoning in high school students (14-15 years old) in Mexico. The study consists of designing and applying a sequence of didactic activities that simulate a real situation virtually. The activities are organized through a Hypothetical Learning…

Virtual reality recently expanded to collaborative and social networking environments where users interact with virtual characters (VCs) of various appearances and behaviors, often impacting the quality of experience. In this paper, we present preliminary survey results of perceptions about characteristics of VCs and a user study of a VR lecture…

Mobile technology melds the mobile learner's authentic real and virtual worlds, enabling increasingly untethered personalized, learner-determined language learning opportunities. This article introduces an evidence-based framework founded upon cumulative findings from a number of the authors' recent and ongoing research projects. This framework…

Mexico is a country where seismic events occur in a daily basis. Since 1990, the national seismological service has reported various earthquakes, in some cases they usually imperceptible, it doesn't ensure that the population cannot be injured, there for, it is important to keep the entire population informed and prepared in the event of an…

This paper describes how an Immersive Virtual Reality (VR) Classroom in a secondary school in Singapore is used to enhance learning through visualization and deepen understanding of science and increase interest and enjoyment in science. The VR Classroom is a futuristic classroom that taps the affordances of VR and AR to enhance HCI…

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…

The emergence of virtual worlds and simulation games provide ample opportunities for developing cultural competence by offering a visual, contextual, immersive, and interactive experience. Learners can benefit from contextual interactions and develop cultural competencies by fulfilling quests or exploring the environment. However, most of the…

This paper discusses a model for structuring resources for automatic assessment in scientific education by means of textual descriptions. This study aims to support instructors in extending teaching strategies and expanding formative assessment in virtual communities of practice. The strategy to achieve these goals involves the implementation of a…

The Euroversity Network project (2011-2014) has built a Good Practice Framework (GPF) that functions as a heuristic for course and activity designers wishing to develop courses and other materials for use in a range of virtual worlds. This framework has been tested with a number of courses during the running of the project and the aim is that it…

How can educators make use of augmented reality technologies and practices to enhance learning and why would we want to embrace such technologies anyway? How can an augmented reality help a learner confront, interpret and ultimately comprehend reality itself ? In this article, we seek to initiate a discussion that focuses on these questions, and…

This paper presents the findings from a qualitative study on collaborative CALL design and implementation carried out with two groups of postgraduate language-teacher trainees who designed and piloted nine virtual language resource centres (VLRC) at 16 educational institutions of different levels and contents for an academic year. The project was…

In this paper we explore students' engagement in a new media enhanced problem-based learning (PBL) environment and investigate the characteristics of these environments that facilitate learning. We investigated both student experiences using a new media enhanced PBL environment and the specific elements students found most supportive of their…

This paper discusses issues of representation in the use of scientific visualizations, specifically those used for biomedical applications, and the implications of those issues to interface design. Topics addressed include the benefits of research into the generation of virtual simulation (virtual reality) and the importance of realism. (Contains…

The study summarized in this paper explored policies for improving open online content development projects with respect to growing the development community and improving the quantity and quality of materials developed. The study made use of dynamic feedback simulation and interviews with the members of an established content development…
