    360-degree videos offer new features to extend video-based learning scenarios. In combination with virtual reality (VR) displays such as full-feature or cardboard displays the use of 360-degree video can further support the feeling of immersion and provide more degrees of freedom to look around. This paper presents preliminary results from an interpretive case study (n=16) evaluating the use of 360-degree videos for video reflection of teacher training sessions in a business education context. In two courses students were offered to record their teaching sessions with a 360-degree video camera in order to reflect on their teaching performance. The process of video reflection consisted of watching the video multiple times and answering specific questions on didactics, content and performance. For this case study participants could explore three viewing experiences, a head-mounted display, a cardboard viewer and a web-based player. Based on their experiences made, they were interviewed focusing on the usefulness for video-based self- reflection. Preliminary results show that 360-degree videos are embraced positively and perceived more useful than regular video for reflection. However, challenges were identified for the scalability and usability of 360-degree video content

    Knowledge Construction of 3D Geometry Concepts and Processes Within a Virtual Reality Learning Environment

    A consensus has emerged within the mathematics education community about the limitations of traditional approaches for teaching and learning 3D geometry. Therefore, it has been suggested that new approaches based on the use of computers need to be adopted. One such new approach that has been proposed utilises Virtual Reality Learning Environment (VRLE). This paper reports on the initial phases of a research study whose major aim is to design and evaluate a VRLE to facilitate the construction of knowledge about 3D geometry concepts and processes. This research study investigates two primary school students’ construction of 3D geometry knowledge whilst engaged within a VRLE developed by the researcher. A design experiments research methodology was employed in this study. This is research that iterates through cycles of design and research with the objective of arriving at theoretical and design principles that will have application both within and beyond the immediate research study. Therefore, the results being reported in this paper will be used to inform the modification not only of the VRLE but also of theoretical frameworks underlying the design and implementation of VRLEs

    Cloud-Based Collaborative 3D Modeling to Train Engineers for the Industry 4.0

    In the present study, Autodesk Fusion 360 software (which includes the A360 environment) is used to train engineering students for the demands of the industry 4.0. Fusion 360 is a tool that unifies product lifecycle management (PLM) applications and 3D-modeling software (PDLM—product design and life management). The main objective of the research is to deepen the students’ perception of the use of a PDLM application and its dependence on three categorical variables: PLM previous knowledge, individual practices and collaborative engineering perception. Therefore, a collaborative graphic simulation of an engineering project is proposed in the engineering graphics subject at the University of La Laguna with 65 engineering undergraduate students. A scale to measure the perception of the use of PDLM is designed, applied and validated. Subsequently, descriptive analyses, contingency graphical analyses and non-parametric analysis of variance are performed. The results indicate a high overall reception of this type of experience and that it helps them understand how professionals work in collaborative environments. It is concluded that it is possible to respond to the demand of the industry needs in future engineers through training programs of collaborative 3D modeling environments

    Digital service analysis and design : the role of process modelling

    Get PDF
    Digital libraries are evolving from content-centric systems to person-centric systems. Emergent services are interactive and multidimensional, associated systems multi-tiered and distributed. A holistic perspective is essential to their effective analysis and design, for beyond technical considerations, there are complex social, economic, organisational, and ergonomic requirements and relationships to consider. Such a perspective cannot be gained without direct user involvement, yet evidence suggests that development teams may be failing to effectively engage with users, relying on requirements derived from anecdotal evidence or prior experience. In such instances, there is a risk that services might be well designed, but functionally useless. This paper highlights the role of process modelling in gaining such perspective. Process modelling challenges, approaches, and success factors are considered, discussed with reference to a recent evaluation of usability and usefulness of a UK National Health Service (NHS) digital library. Reflecting on lessons learnt, recommendations are made regarding appropriate process modelling approach and application
