[publication] Development of an Amazon Alexa App for a University Online Search #alexa #research #tugraz

Our chapter about “Development of an Amazon Alexa App for a University Online Search” for the HCII 2022 conference got published.

Today, our homes become smarter and smarter. We started to interact with our home with Intelligent Personal Assistants, like Amazon Alexa. In this paper we want to present and give a review on the Alexa skill developed for an online search for resources like rooms, courses, and persons. The goal is to provide the users an easy-to-use way to ask for information like phone numbers, e-mail addresses, room details, … and the Alexa Skill should provide this information also in an easy understandable way. We will describe how we solved to formulate suitable search queries from spoken Alexa commands and how we presented them to the user accordingly. Other obstacles like the presentation of the search results, due to the limited context and prioritization for individual search results, to the user will be discussed.

[publication] Evaluation of Mixed Reality Technologies in Remote Teaching #VirtualReality #tugraz #education

Our chapter for the HCII conference 2022 about “Evaluation of Mixed Reality Technologies in Remote Teaching” got published.

The trend towards remote teaching is steadily increasing and intensified by the current situation of the global pandemic. This is a particular challenge for subjects with a high practical relevance, such as mining engineering education, as practical experiences and on-site excursions are an integral part of the curriculum. In face-to-face teaching settings, mixed reality technologies are already considered a promising medium for the implementation of e.g., virtual field trips. Based on this, the current study addresses the question to what extent the integration of mixed reality technologies is suitable for remote teaching and which strengths and challenges are perceived by students and teachers. For this purpose, two 60-min remote lectures in the field of mining engineering were conducted, in which the use of mixed reality was tested on the basis of shared 360° experiences and 3D models and evaluated by students and teachers. Results reveal that the use of mixed reality in remote teaching was perceived as useful, enabled a realistic experience and improved students’ understanding of presented theory compared to traditional teaching methods. In this paper, we discuss possible potentials and risks of using mixed reality in remote teaching and derive directions for further research.

[publication] Math Trainer as a Chatbot Via System (Push) Messages for Android #education #TechnologyEnhancedLearning

Our research titled “Math Trainer as a Chatbot Via System (Push) Messages for Android” got published in the newest issue of the International Journal of Interactive Mobile Technologies.

In the recent years, as technology grew, so did the chatbot technology. More and more companies and people are using and reaping the benefits from them. This paper shows how a chatbot for mathematical tasks, named mathbot, was developed. The chatbot uses mathematical exercises from the “Schulapps” of the LearningLab of Graz, University of Technology and combines them with textual questions to provide a useful utility for practicing. It is shown that such a chatbot could be useful for pupils and teachers by evaluating a test run in an elementary school.

[book] micro:bit – Das Schulbuch #digitaleGrundbildung

Das “micro:bit – Das Schulbuch” ist nun in der zweiten Auflage online verfügbar und gründsätzlich auch für den Lehrplan des neuen Unterrichtsfaches “Digitale Grundbildung” geeignet:

Auf diesem WIKI finden sich Beispiele und weiteres Material zum österreichischen Schulbuch über den BBC micro:bit. Seit September 2022 gibt es eine zweite adaptierte und erweitere Auflage des Buches. Das gedruckte Buch dient dabei als Ideengeber und kann ausreichen, um alle darin vorgestellten Aufgaben zu lösen. Sollten Hinweise, Tipps oder Lösungen zu den Aufgaben gesucht werden, wird man auf dieser Webseite fündig. Die erste Auflage des Buches stellt exemplarisch 22 Projekte vor, in der zweiten Auflage finden sich 39 Beispiele, die in der Sekundarstufe I in einem fächerübergreifenden, projektorientierten Unterricht eingesetzt werden können. Es ist kein reines Informatik- oder “Programmierlernbuch”. Es verwendet den BBC micro:bit als Grundlage für spannende und kreative Projekte. Der notwendige Code kann, wenn man einmal eine Idee für den Algorithmus gefunden hat, ganz einfach direkt im Webbrowser erstellt, getestet und danach bei Bedarf heruntergeladen und auf einem realen micro:bit installiert werden.

Das ganze Buch und das Wiki findet man hier: https://microbit.eeducation.at/wiki/Hauptseite

Weiters gibt es auf iMooX.at auch einen MOOC der Lehrer:innen beim Einsatz unterstützen soll: [Link zum kostenlosen Online-Kurs]

[app] Mulitplikationstrainer #ios #tugraz #learninglab

Im Rahmen unseres Learninglab ist wieder eine mobile Applikation für Kinder im Rahmen einer Qualifikationsarbeit entstanden – ein Mulitplikationstrainer:

Expand your multiplication skills.
You can start a short game over ten rounds or an online game.If you reach enough points at the short game, you unlock the next level with higher complexity. Or our Online-System creates your multiplications. The system enables you to see your calculations and errors online.
So you are able to analyze your errors and improve your skills. If you play the online mode, you need an account from the learning lab of the TU Graz.

[publication] School Start Screening Tool #edil21 #research #app

Our contribuation to this year ED-Media 2021 conference about “School Start Screening Tool” got published. The slides are already here online.

This paper concentrates on the implementation of a new screening method in Austrian schools to assess children and find out if they have any special educational needs in educational areas like phonology, counting, knowledge of letters and numbers and others. The underlying structure of the assignments was developed by developmental psychologists from the University of Graz and the University of Vienna and then implemented as a mobile application for Android tablets. For testing and evaluation purposes, the app’s prototype was first used voluntary by multiple Austrian schools. Furthermore, the mobile application had to be fully functional when offline as well as a central web application had to be developed to give the developmental psychologists access to the screening results. However, the main goal was to develop the application in a way that especially children without sufficient skills in reading and writing are able to understand the assignment’s tasks and to perform input.
