Technology to support collaborative learning has come a long way. Interactive tabletops support collaboration when correctly integrated in activity design. While these devices can now, in principle, be purchased by the general public, wide adoption in schools is hindered by their high cost and lack of mobility. In this paper, we analyze the…

This paper explores the concept of self-efficacy and its impact on individual performance on a mobile learning application. Self-efficacy refers to one's belief in their ability to achieve their goals and is a key factor in everyday life. To investigate the relationship between self-efficacy and performance, we conducted an experiment with 104…

One of the world's most famous pyramids is not located in Egypt but is on a music album cover by the band Pink Floyd. However, not a pyramid but a prism, the iconic image of a beam of light turning into a rainbow is a powerful symbol that captures the complexities of colour perception across cultures and individuals. This study examines how…

Theoretical background: Learning in virtual realities (VR) has become increasingly important. In this context, VR appears to be particularly conducive to affective learning objectives, such as perspective-taking in VR actors. Previous research has often focused on investigating cause-effect relationships that focus on the direct effects of…

Mobile devices, augmented reality (AR), and outdoor games can be mobilized to promote Education for Sustainable Development and, thus, to sensitize to nature conservation. The EduCITY project combines mobile learning, AR, and environmental sensors towards sustainability education and creates opportunities for citizens to contribute to their city's…

This paper proposes a didactic design that is centered around an immersive, multilinear narrative in virtual reality as a means of illustrating human life on the edge of technological singularity. It explores the potential of narrative scenarios to trigger a discourse from users' perspective. Affective Computing is taken as a use case. It is a…

The local environment can be explored to sustain effective sustainability learning. With this aim, new learning methodologies can be fostered, namely mobile and game-based learning, as is the case of the EduPARK app. This app supports innovative learning strategies through treasure hunt games, integrating multimedia and augmented reality…

This paper introduces web viewers for educational VR contents. Recently, many types of VR goggles have been released as commercial products and many entertainment applications for them have been created. However, educational VR contents have been created so far are not so many because the creation of VR contents is time consuming task. We need to…

Introduction: This study aimed to develop a cost-effective suturing and knot typing simulator that aligns with the expectations of experts, addressing the need for affordable yet high-quality medical training tools. The focus was on assessing the efficacy of a silicone skin suture task trainer, created through a 3D printed mold, for use in mobile…

The authors developed, implemented, and evaluated a digital simulation game for media education in teacher training. The aim of the simulation game is to simulate decision-making processes in schools for the implementation of hybrid teaching in the context of the pandemic. The question is whether the participation in a digital simulation games…

These proceedings contain the papers of the 21st International Conference on Cognition and Exploratory Learning in the Digital Age (CELDA 2024), held in Zagreb, Croatia, from 26 to 28 October 2024 and organized by the International Association for Development of the Information Society (IADIS). The CELDA conference aims to address the main issues…

To drive effective change towards sustainable development, several courses of action have been devised, and education was pointed as a way to attain this goal. Recognizing the impact of learning in context, it is essential to develop innovative educational proposals that bring schools into other social contexts. This study aims to present, albeit…

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…

This study used Bloom's Revised Taxonomy to examine 30 questions produced for a mobile quiz game with augmented reality contents to be explored in a formal learning context, in an urban green park, in Portugal. The game was co-created by 14 in-service teachers involved in a 50h training that aimed to promote the collaborative development of open…

These proceedings contain the papers and posters of 21th International Conference on Mobile Learning (ML 2025) and 10th International Conference on Educational Technologies 2025 (ICEduTech 2025), organised by the International Association for Development of the Information Society in Madeira Island, during 1-3 March 2025.
