[publication] Speech-based Learning with Amazon Alexa #tugraz #research #edil21

Our contribuation to this year ED-Media 2021 conference about „Speech-based Learning with Amazon Alexa“ got published. The slides are already here online.

Abstract:
Almost every child and adult today have access to the Internet and different technologies like smartphones, tablets and co. Scientists recognized this very quickly and started to create a whole new way of learning. Therefore, learning applications have been developed to increase student and adult interest in studying and training. This paper describes the development of a speech-based Alexa Skill for educational purposes. The main goal is to help students as well as adults to learn and train mathematical basic calculation types. The skill was designed in a way that young students as well as adults can interact with Alexa in their own words. Therefore, the skill „Mathe Rätsel“ (Eng.: „Math riddle“) offers two difficulties to meet the needs of young and old users.

Erschienen: Projektbericht zum OER-Schnittstellen an der TU Graz und OEAA #oer #OEAA #openeducation

Die Beteiligten haben ihre Arbeit rund um OER-Schnittstellen zwischen den Systemen der TU Graz und zum österreichweiten OER-Refereratory der Universität Wien bereits in zwei wissenschaftlichen Publikationen publizieren können. Jetzt folgt der noch etwas ausführlichere Projektbericht:

Um einen breiten Zugang zur Bildung und großzügige Nutzung von Bildungsressourcen zu ermöglichen, setzt auch die Technische Universität Graz (TU Graz) auf offene Bildungsressourcen (Open Educational Resources, kurz OER). Der Arbeitsbericht beschreibt die technologischen Entwicklungen und Prozesse, damit Lehrende der TU Graz das eigene Lernmanagementsystem für die Veröffentlichung von OER nutzen können. Es wird nachgezeichnet, wie Schnittstellen und Prozesse gestaltet wurden, um Lern- und Lehrressourcen der TU Graz mit entsprechenden Metadaten auszuzeichnen, um sie über das universitätseigene OER-Repositorium und entsprechenden Schnittstellen für das OER-Fachportal der Universität Wien einer breiten Öffentlichkeit recherchierbar anzubieten. Nur entsprechend qualifizierte Lehrende der TU Graz erhalten die Berechtigung für die Nutzung des neuen OER-Plug-In. Der Projektbericht schließt mit Empfehlungen für Nachahmer/innen.

[publication] Experiences Based on a Major Information Server #tugraz #research

Together with my colleagues we published an article about „Experiences Based on a Major Information Server“ in the Journal of Transactions on Internet Research.

Abstract:
In this paper we describe lessons we have learnt from building up a webserver with reliable information over a period of ten years. We show how we have tried to overcome often encountered weaknesses and thus encourage the community to follow our suggestions. We also point out that much research and development work remains to be carried out.

[lecture] Research approaches and methods in technology-enhanced learning #TEL #research

Sandra was giving a lecture on „Research approaches and methods in technology-enhanced learning“ and therefore we did a rough translation of our L3T-chapter to make a hand out for the students.

Abstract:
This article offers an orientation on how research is done in technology-enhanced learning. Therefore, three different approaches to research in the interdisciplinary field will be presented first: hypothesis and theory testing, hypothesis and theory generating, and design oriented methods. Subsequently, some research methods are assigned to the research process – data collection, data analysis, development – and outlined. Finally, hints on the choice of a research method are given and a typical challenge in the field is mentioned.

[publication] Simulation data visualization using mixed reality with Microsoft HoloLensTM #AR #VR #tugraz

My PhD-Students wrote a chapter about the usage of Microsoft Hololens „Simulation data visualization using mixed reality with Microsoft HoloLensTM„. Now it got published within the book „New Perspectives on Virtual and Augmented Reality„.

Abstract:
Simulations and test beds are very difficult topics, especially for non-experienced students or new employees in the mechanical engineering domain. In this chapter, a HoloLens app and a CAD/Simulation workflow are introduced to visualize CAD models and sensor and simulation data of a test run on an air conditioning system test bed. The main challenge is to visualize temperature and pressure changes within opaque parts, such as tubes, compressors, condensers or electrical expansion valves. The HoloLens app supports various simulations and CAD visualizations. We exemplary implemented colouring the temperature or pressure changes of the test bed parts as Mixed-Reality (MR) overlays. The main purpose of the HoloLens app is to reduce the learning effort and time to understand such simulations and test bed settings. Additionally, the app could be used as a communication tool between different departments to transfer experiences and domain specific knowledge.

[publication] COVID-19 Epidemic as E-Learning Boost? Chronological Development and Effects at an Austrian University against the Background of the Concept of “E-Learning Readiness” #covid19 #tugraz

Our first research article concerning the situation of COVID-19 titled „COVID-19 Epidemic as E-Learning Boost? Chronological Development and Effects at an Austrian University against the Background of the Concept of “E-Learning Readiness” is published right now.

Abstract:
The COVID-19 crisis influenced universities worldwide in early 2020. In Austria, all universities were closed in March 2020 as a preventive measure, and meetings with over 100 people were banned and a curfew was imposed. This development also had a massive impact on teaching, which in Austria takes place largely face-to-face. In this paper we would like to describe the situation of an Austrian university regarding e-learning before and during the first three weeks of the changeover of the teaching system, using the example of Graz University of Technology (TU Graz). The authors provide insights into the internal procedures, processes and decisions of their university and present figures on the changed usage behaviour of their students and teachers. As a theoretical reference, the article uses the e-learning readiness assessment according to Alshaher (2013), which provides a framework for describing the status of the situation regarding e-learning before the crisis. The paper concludes with a description of enablers, barriers and bottlenecks from the perspective of the members of the Educational Technology department.
