[publication] Finding and Exploring Commonalities Between Researchers Using the ResXplorer

Our publication about “Finding and Exploring Commonalities Between Researchers Using the ResXplorer” at this year HCII conference in Crete, Greece is now online available.

Abstract:

Researcher community produces a vast of content on the Web. We assume that every researcher interest oneself in events, persons and findings of other related community members who share the same interest. Although research related archives give access to their content most of them lack on analytic services and adequate visualizations for this data. This work resides on our previous achievements we made on semantically and Linked Data driven search and user inter- faces for Research 2.0. We show how researchers can find and visually explore commonalities between each other within their interest domain, by introducing for this matter the user interface of “ResXplorer”, and underlying search infrastructure operating over Linked Data Knowledge Base of research resources. We discuss and test most important com- ponents of “ResXplorer” relevant for detecting commonalities between researchers, closing up with conclusions and outlook for future work.

[publication] Markov Chain and Classification of Difficulty Levels Enhances the Learning Path in One Digit Multiplication

Our second publication at this year HCII conference in Crete, Greece is about “Markov Chain and Classification of Difficulty Levels Enhances the Learning Path in One Digit Multiplication“.

Abstract:

In this work we focus on a specific application named “1×1 trainer” that has been designed to assist children in primary school to learn one digit multiplications. We investigate the database of learners’ answers to the asked questions by applying Markov chain and classification algorithms. The analysis identifies different clusters of one digit multiplication problems in respect to their difficulty for the learners. Next we present and discuss the outcomes of our analysis considering Markov chain of different orders for each question. The results of the analysis influence the learning path for every pupil and offer a personalized recommendation proposal that optimizes the way questions are asked to each pupil individually.

[iPhone] Learning Styria

Learning StyriaIm Rahmen unserer Vorlesung “Mobile Applications 2014” ist auch das Lernspiel “Learning Styria” entstanden. Es geht darum, das östereichische Bundesland Steiermark näher kennenzulernen und Städte, Berge, Flüsse zu lokalisieren:

„Learning Styria“ gibt dir die Möglichkeit die Steiermark auf spielerische Weise kennen zu lernen.
Wähle unter verschiedenen Kategorien aus (Städte, Seen, Berge, Gewässer) und versuche diese auf der Steiermark Karte zu finden.
Je näher du dran bist desto mehr Punkte bekommst du, solltest du sehr weit entfernt sein werden Punkte abgezogen.

[publication] Attention Profiling Algorithm for Video-based Lectures

Our first publication at this year HCII conference in Crete, Greece about “Attention Profiling Algorithm for Video-based Lectures” is now online available as prelimiary version. The slides are already published here.

Abstract:

Due to the fact that students’ attention is the most crucial resource in a high-quality course it is from high importance to control and analyze it. This could be done by using the interaction and the communication because they are known as valuable influencing factors of the attention. In this publication we introduce a web-based information system which implements an attention-profiling algorithm for learningvideos
as well as live-broadcastings of lectures. For that different methods of interaction are offered and analyzed. The evaluation points out that the attention profiling algorithm delivers realistic values.

[iPhone] Shoppingliste

ShoppinglisteIm Rahmen unserer Vorlesung “Mobile Applications 2014” ist auch die App Shoppingliste programmiert worden. Wie unschwer zu erraten ist, kann man sich damit seine persönliche Einkaufsliste erstellen:

Einkaufskorb ist eine einfache, trotzdem effiziente und einfach zu bedienende App.
Mit dieser App gehören die Einkaufszettel der Vergangenheit an.
Die vorgegebenen Kategorien und Artikel ermöglichen es, die Struktur der App zu verstehen
und neue Artikel wie auch Kategorien hinzuzufügen.
Außerdem werden die Daten mit der iCloud synchronisiert, wodurch es auch möglich ist, auf verschiedenen
Geräten Daten zu speichern und/oder zu ändern.

[iPhone] Falling Flamingo Math

Falling FlamingoIm Rahmen unserer Vorlesung “Mobile Applications 2014” ist das Spiel Falling Flamingo entstanden. Also nicht nur, dass es schwer ist den Flamingo durch die Levels zu bringen, nein man darf auch noch mathematische Aufgaben lösen – also dann mal los :-)

Falling Flamingo Math ist ein iOS Spiel, welches dir dabei hilft deine Fähigkeiten im Kopfzurechnen spielerisch zu verbessern.
Du kannst zwischen 4 Schwierigkeitsgraden und 6 Charakteren wählen. Jeder Charakter hat unterschiedliche Eigenschaften. Das Ziel des Spiels ist es so lange wie möglich am Leben zu bleiben, indem du deinen Charakter durch die Plattformen nach unten navigierst und versuchst die Fragen richtig zu beantworten. Aber pass auf die Items auf! Manche Items helfen dir weiter zu kommen, aber andere machen dir das Leben schwer. Viel Spaß beim Spielen, Teilen und Herausfordern deiner Freunde via GameCenter.

[publication] The Maker Movement. Implications of new digital gadgets, fabrication tools and spaces for creative learning and teaching

Together with Swapna Kurma and Sandra I did an short intrdocution to the increasing maker movement which was published right now: “The Maker Movement. Implications of new digital gadgets, fabrication tools and spaces for creative learning and teaching“.

The “Maker Movement” deals with innovative forms of production and do-it-yourself work. It is not only a way for new business models and developments, e.g. using 3D print or other new digital tools and gizmos, but also influencing education. This paper introduces several diverse terms (from FabLabs to Hackerspaces) and gives insights into background, practice and existing experiences from Maker Movement in educational settings amongst all age groups. As a conclusion, the authors present reasons why practitioners and researcher should consider its educational potential. Besides its creative and technological impacts, learning by making is an important component of problem-solving and relating educational content to the real world. Besides this, digital tools for making are not expensive, for example apps for mobile devices or rents for 3D printer (compared with desktops in 1:1 settings). The Maker Movement is seen as an inspiring and creative way to deal with our world, it is aware of ecological challenges and of course, and it is able to develop technological interest and competences casually.
Finally, the authors give recommendation for reading for all who got interested in making.

[publication] Learning Analytics: From Theory to Practice – Data Support for Learning and Teaching

Our contribution at this year International Computer Assisted Assessment Conference (CAA 2014) about “Learning Analytics: From Theory to Practice – Data Support for Learning and Teaching” is now online available.

Abstract:

Much has been written lately about the potential of Learning Analyt- ics for improving learning and teaching. Nevertheless, most of the contributions to date are concentrating on the abstract theoretical or algorithmic level, or, deal with academic efficiencies like teachers’ grading habits. This paper wants to fo- cus on the value that Learning Analytics brings to pedagogic interventions and feedback for reflection. We first analyse what Learning Analytics has to offer in this respect, and, then, present a practical use case of applied Learning Analytics for didactic support in primary school Arithmetic.
