[publication] Support of Video-Based lectures with Interactions – Implementation of a first prototype

Our contribution at this year ED-MEDIA conference in Tampere, Finnland about “Support of Video-Based lectures with Interactions – Implementation of a first prototype” is now online available. The slides have alreday been published here.

Abstract:

In general videos have a more or less consuming character without any interaction possibilities. Due to this fact a web-based application is developed which offers different methods of communication and interaction to a certain learning-video. This should help attendees to avoid that they become tired and annoyed. The lecturer is able to use interactions to omit whether learners are able to understand the content of the video. For instance the developed web-application offers the possibility to add multiple-choice-questions at predefined positions. Furthermore there are many different kind of analysis as for example a detailed attention-profile. In this publication the implementation of a first prototype is described as well as a first field study which points out that learners? interactions and engagements increased arbitrarily.

Inverse Blended Learning – Why we need and how we try it!

Sandra and I prepare a MOOC about Free Learning with the Web in German language at the imoox.at platform. It will be of course an OER course (CC BY), but what is even more challenging: The target group are people with some or even less Internet know-how without any e-learning background.
Thinking about the consequences on how we may adress them (not only before, but even while the course) and not being limited on the pure online aspect, we are developing a “inverse blended learning” scenario.
We will bring the open online course more into the “concrete”, “practical” and “real” surrounding and context of the learners. (And we are sure that this is not only interesting for our “very special target group”).
Our first ideas are:

  • Delivering a .pdf for own print, but also printed versions (for free) in local organisations (in German speaking countries). Following the idea that people need some additional learning material we will also provide a small textbook for the course.
  • Asking supporter for local meetings of learners, eventually parallel presence courses to the online course. Due to the fact that learning is a highly social process we would like to give learners the chance to be part of an online as well as offline community.
  • Inviting to a central final closing event.

… and we are happy to get your feedback on this!

[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.
