Digitale Lehre an und rund um der Technischen Universität Graz
Neue Entwicklungen
Im Rahmen der GMW 2020 Tagung hat Clarissa zwei Beiträge von uns vorgestellt – der zweite nun hatten den Titel „Der Ansatz der „Citizen Science“ bei der Erstellung von Lehrmaterialien in einem Hochschulprojekt„. Hier gibt es noch die Vortragsfolien:

At this year EDMedia conference (online) we did a publication about „The Use of Alexa for Mass education“.
Abstract:
The amount of digitalized information increases day by day. Everyone connected to the internet through different devices or interfaces can acquire information of specific topics and interests at every time on every place. Nowadays, nearly every child owns a mobile device or at least has access to a mobile device connected to the internet. The main focus of children is to watch videos or play games on their device, so they always see it as an interesting, entertaining virtual friend. The use of mobile devices containing apps which deliver selected information opens a very interesting channel to deliver knowledge in a hidden way to children. This research deals with the development of an Alexa skill prototype to train 1×1 calculation skills of children in primary school in a very funny and playfully way. To evaluate the speech-assistant technology connected to an education game, a field study in was realized. As the Alexa speech-assistant is anyway absolutely magnetic to children, the feedback of the 1×1 calculation skill was better than expected and motivated us to enhance the base functionalities.

Einen interaktiven Workshop gestalten: geschenkt. Doch wie bringt man ihn in den virtuellen Raum? Ich habe die Herausforderung in der COVID-19-Krise angepackt und ein Workshopdesign, mit dem wir im Präsenzformat bei der Universität Passau (Lehre+ Hochschuldidaktik) gute Erfahrungen gemacht haben möglichst 1:1 in den virtuellen Raum übertragen und dort mit Lehrenden der FH Salzburg durchgeführt.
Im Beitrag wird das Konzept eines Präsenzworkshops zur Einführung von MOOCs (Massive Open Online Courses) für Lehrende an Hochschulen vorgestellt, wie es im Jahr 2013 mit hohen Anteilen von Interaktion und Gruppenarbeit entwickelt wurde. In der Folge der COVID-19-Krise und Umstellung auf Home Office und Online-Begegnungen wurde versucht, das methodisch-didaktische Konzept möglichst gleichartig in den digitalen Raum zu übertragen. Im Artikel wird beschrieben, welche Tools dabei zum Einsatz kamen und wie sie sich auf die Arbeitsweisen und -ergebnisse ausgewirkt haben.
Man kann jetzt nicht nur nachlesen wie wir Workshops für MOOC-Einsteiger/innen gestalten in Präsenz und Online gestalten, sondern auch, auf was man beim Übertragen ins Online-Format achten sollte.
The first presentation at this year EDMedia conference (online) was about „The use of Alexa for mass education“. Find here the slides of my talk:

Our publication about „Concepts for E-Assessments in STEM on the Example of Engineering Mechanics“ got published in the International Journal for Emerging Technologies in Learning (i-JET).
Abstract:
We discuss if and how it is possible to develop meaningful e-assessments in Engineering Mechanics. The focus is on complex example problems, resembling traditional paper-pencil exams. Moreover, the switch to e-assessments should be as transparent as possible for the students, i.e., it shouldn’t lead to additional difficulties, while still maintaining sufficiently high discrimination indices for all questions. Example problems have been designed in such a way, that it is possible to account for a great variety of inputs ranging from graphical to numerical and algebraic as well as string input types. Thanks to the implementation of random variables it is even possible to create an individual set of initial values for every participant. Additionally, when dealing with complex example problems errors carried forward have to be taken into account. Different approaches to do so are detailed and discussed, e.g., pre-defined paths for sub-questions, usage of students’ previous inputs or decision trees. The main finding is that complex example problems in Engineering Mechanics can very well be used in e-assessments if the design of these questions is well structured into meaningful sub-questions and errors carried forward are accounted for.

Our chapter about „Mixed Reality Books: Applying Augmented and Virtual Reality in Mining Engineering Education“ got published in the book „Augmented Reality in Education“.
Abstract:
Abstract Chapter
This chapter deals with the integration of Augmented and Virtual Reality (AR/VR) elements into academic mining education. The focus lies on the didactical approach within the EU-funded MiReBooks (Mixed Reality Books) project. The project aims to develop a series of AR- and VR-based interactive mining manuals as a new digital standard for higher education across European engineering education. By combining AR and VR technologies, it is possible to address current challenges in mining education in an innovative way. These virtual applications should make otherwise impossible and dangerous situations accessible to students. Classical paper-based teaching materials are enriched with AR content and translated into pedagogically and didactically coherent manuals for integrative use in the classroom. The authors explore how AR and VR instruments can be effectively integrated into teaching. The results of a broad evaluation of AR/VR-based lectures are presented and discussed in this chapter. The experiences and findings are summarized in a decision matrix for the use of AR/VR-based technologies in teaching.

Our first resarch using Amazon’s Alexa for Learning are now published, named „A Voice-Enabled Game Based Learning Application using Amazon’s Echo with Alexa Voice Service: A Game Regarding Geographic Facts About Austria and Europe“ in the International Journal of Interactive Mobile Technologies (iJIM) .
Abstract:
Journal’s Homepage
An educational, interactive Amazon Alexa Skill called “Österreich und Europa Spiel / Austria and Europe Game” was developed at Graz University of Technology for a German as well as English speaking audience. This Skills intent is to assist learning geographic facts about Austria as well as Europe by interaction via voice controls with the device. The main research question was if an educational, interactive speech assistant application could be made in a way such that both under-age and full age subjects would be able to use it, enjoy the Game Based Learning experience overall and be assisted learning about the Geography of Austria and Europe. The Amazon Alexa Skill was tested for the first time in a class with 16 students at lower secondary school level. Two further tests were done with a total of five adult participants. After the tests the participants opinion was determined via a questionnaire. The evaluation of the tests suggests that the game indeed gives an additional motivational factor in learning Geography.

Zusammen mit Sandra und Kristin haben wir einen kurzen Beitrag zur Maker Education im Medienpädagogik-Praxisblog geschrieben und dabei auf 5 verschiedene mögliche Aufgabenstellungen hingewiesen:
We are very pleased that our short chapter about „Potential of Bots for Encyclopedia“ for the special issue on „Digital Heritage and Related Tools„ got pusblished.
Abstract:
The wide range of applications and the capability to process and understand natural languages made chatbots very popular. Besides that, many applications chatbots are also used as information retrieval tools. Chatbots are changing the way users search for information. This document focuses on a chatbot that is used as an information retrieval tool. The chatbot enables information search in natural language in a geography domain. In case of a large number of search results, the chatbot engages users with clarification questions. It also provides support to users when uploading multimedia content to the website.

An der TU Graz sind im Rahmen eines kleinen Projektes vier kurze Videos entstanden um Studierenden den Einstieg in die Programmiervorlesungen zu erleichtern. Unter anderem wird gezeigt wie man sich eine virtuelle Maschine einrichtet oder wie man GitLab verwenden kann. Die Videos sind offen und frei zugänglich.
