The main objective of this study is the design and validation of an educational methodological model based on the use of immersive technological resources (Augmented Reality -- AR) to improve learning processes in secondary education science subjects (Biology and Geology). The process was developed based on three main quantitative studies: an…

The appreciation and understanding of gas generation through processes is vital in biochemical education. In this work, an augmented reality tool is reported to depict the redox reaction between hydrogen peroxide and sodium hypochlorite solutions, two ubiquitous oxidizing agents, to create oxygen, a combustible gas. As it operates out of…

How can we help students develop an understanding of chemistry that integrates conceptual knowledge with the experimental and computational procedures needed to apply chemistry in authentic contexts? The current work describes ChemVLab+, a set of online chemistry activities that were developed using promising design principles from chemistry…

Various cognitive aids (such as change of color, arrows, etc.) are provided in virtual environments to assist users in task realization. These aids increase users' performance but lead to reduced learning because there is less cognitive load on the users. In this paper we present a new concept of procedural guidance in which textual information…

Educators must address several challenges inherent to the instruction of scientific disciplines such as physics -- expensive or insufficient laboratory equipment, equipment error, difficulty in simulating certain experimental conditions. Augmented reality (AR) can be a promising approach to address these challenges. In this paper, we discuss the…

A small group of high school students performed a virtual laboratory experiment in Second Life that mimicked a real experiment in both its appearance and procedure. Lab report grades were equivalent to report grades for hands-on experiments, and the quality of students' results was similar. Results of an attitudinal survey show that students…

We present an immersive virtual reality (VR) application for physics education. It utilizes a recent physics engine developed for the PC gaming market to simulate physical experiments correctly and accurately. Students are enabled to actively build their own experiments and study them. A variety of tools are provided to analyze forces, mass, paths…

These proceedings contain the papers of the 10th International Conference on Mobile Learning 2014, which was organised by the International Association for Development of the Information Society, in Madrid, Spain, February 28-March 2, 2014. The Mobile Learning 2014 International Conference seeks to provide a forum for the presentation and…

This article discusses the relationship between procedural and conceptual problem solving in a computer-supported collaborative learning (CSCL) environment designed within the field of science education. The contribution of this article, and our understanding of this phenomenon, is anchored in our socio-cultural interpretation, and that implies…

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
