[publication] All about MOOCs

Unser Beitrag für den uDay XIII an der FH Vorarlberg mit dem Titel „All About MOOCs“ ist nun online verfügbar.
Abstract:

Massive Open Online Courses (MOOCs) haben sich mittlerweile als eine neue Form von Bildungsangeboten auch in Europa weitgehend etabliert. Anhand von iMooX, der ersten und einzigen MOOC-Plattform Österreichs, wird im vorliegenden Beitrag verdeutlicht, welche Rahmenbedingungen für die Etablierung einer solchen Plattform geschaffen werden müssen, welche Zielgruppen angesprochen werden und was Teilnehmer/innen zu einer Kursteilnahme motiviert. Abschließend wird ein Ausblick darüber gegeben, welche strategischen Maßnahmen für den nachhaltigen Betrieb einer MOOC-Plattform durch Hochschulen notwendig sind und worin das Weiterentwicklungspotenzial von MOOCs bestehen kann.

[publication] MOOCs as granular systems: design patterns to foster participant activity

Our publication about „MOOCs as granular systems: design patterns to foster participant activity“ is now published as part of the new eLearning papers issue.

Abstract:

MOOCs often suffer from high drop-out and low completion rates. At the beginning of the course, the audience is indeed “massive”; thousands of people wait for the course to begin, but in the end only a low number of participants stay active and complete the course. This paper answers the research question “Is there a specific point during an xMOOC where learners decide to drop out of the course or to become lurkers?” by identifying MOOCs as a challenging learning setting with a “drop-out problem” and a decrease in participant activity after the fourth to fifth course week. These are the first results of a Learning Analytics view on participant activity within three Austrian MOOCs. This “drop-out point” led the paper to introduce a design pattern or strategy to overcome the “drop-out point”: “Think granular!” can be seen as an instructional design claim for MOOCs in order to keep participant activity and motivation high, and that results in three design patterns: four-week MOOCs, granular certificates and suspense peak narratives

[publication] Visualizing Collaborations and Online Social Interactions at Scientific Conferences for Scholarly Networking

Our publication about „Visualizing Collaborations and Online Social Interactions at Scientific Conferences for Scholarly Networking“ at this year World Wide Web Conference is now online available.
Abstract:

The various ways of interacting with social media, web collaboration tools, co-authorship and citation networks for scientific and research purposes remain distinct. In this paper, we propose a solution to align such information. We particularly developed an exploratory visualization of research networks. The result is a scholar centered, multi-perspective view of conferences and people based on their collaborations and online interactions. We measured the relevance and user acceptance of this type of interactive visualization. Preliminary results indicate a high precision both for recognized people and conferences. The majority in a group of test-users responded positively to a set of statements about the acceptance.

[publication] COLINDA: Modeling, Representing and Using Scientific Events in the Web of Data

Our publicaton about „COLINDA: Modeling, Representing and Using Scientific Events in the Web of Data“ at this year „DeRiVE 2015-Detection, Representation, and Exploitation of Events in the Semantic Web“ conference is now online available.
Abstract:

Conference Linked Data (COLINDA)3, a recent addition to the LOD (Linked Open Data) Cloud4, exposes information about scientific events (confer- ences and workshops) for the period from 2002 up to 2015. Beside title, descrip- tion and time COLINDA includes venue information of scientific events which is interlinked with Linked Data sets of GeoNames5, and DBPedia6. Additionally in- formation about events is enhanced with links to corresponding proceedings from DBLP (L3S)7 and Semantic Web Dog Food 8 repositories. The main sources of COLINDA are WikiCfP9 and Eventseer10. The research questions addressed by this work in particular are: how scientific events can be extracted and summa- rized from the Web, how to model them in Semantic Web to be useful for mining and adapting of research related social media content in particular micro blogs, and finally how they can be interlinked with other scientific information from the Linked Data Cloud to be used as base for explorative search for researchers

[publication] What do we know about typical MOOC participants? First insights from the field

Our publication about „What do we know about typical MOOC participants? First insights from the field“ at this year eMOOCs 2015 conference, Mons (Belgium) is now online available.
Abstract:

Massive Open Online Courses became a worldwide phenomenon. Especially in Central Europe it is a subject of debates whether universities should invest more money or not. This research study likes to give first answers about typical MOOC participants based on data from different field studies of the Austrian MOOC-platform iMooX.
It can be pointed out that the typical learner is a student or an adult learner, strongly interested in the course topic or just interested in learning with media and finally with self- contained learning competencies. The research work concludes that MOOCs broaden the educational field for universities and are a possibility to educate the public in a long run.

A great crowdauthoring project

No, it wasn’t us 😀 – I was not my idea, neither Sandra’s. But of course we did not hesitate when we were asked to co-author a paper with 100 authors (from all over the world). The crazy person who organize this all is Abdul Al Lily. He is currently the guy that collects, edits, etc. all comments to our second version of the paper. YES, THIS IS NO JOKE. I really appreciate his idea and hope he will get through all of this. And I am looking forward to the paper (and hope that it will be accepted 😀 – and: cited! with all names! :D)

[publication] Mobile Applications for Math Education – How Should They Be Done?

My contribution about „Mobile Applications for Math Education – How Should They Be Done?“ as part of the book Mobile Learning and Mathematics. Foundations, Design, and Case Studies got published.
Abstract:

Math education in elementary schools is a necessity. In this publication we introduce different math applications for iPhone and iPad developed by students at Graz University of Technology. Both, the technical as well as the pedagogical strategy of these apps are described. Furthermore, a close look at the HCI guidelines are taken and finally enhanced with some crucial facts that in principle an app is able to serve as a learning app for elementary school children. It can be summarized that the successful use of math apps in classroom is more than just a playing with the first app that comes along; it is about a careful design of a didactical approach based on an appropriate learning strategy.

[publication] Towards a Learning-Aware Application Guided by Hierarchical Classification of Learner Profiles #jucs

Our publication about „Towards a Learning-Aware Application Guided by Hierarchical Classification of Learner Profiles“ is published as part of the Special Issue on Learning Analytics.
Abstract:

Learner profiling is a methodology that draws a parallel from user profiling. Implicit feedback is often used in recommender systems to create and adapt user profiles. In this work the implicit feedback is based on the learner’s answering behaviour in the Android application UnlockYourBrain, which poses different basic mathematical questions to the learners. We introduce an analytical approach to model the learners‘ profile according to the learner’s answering behaviour. Furthermore, similar learner’s profiles are grouped together to construct a learning behaviour cluster. The choice of hierarchical clustering as a means of classification of learners‘ profiles derives from the observations of learners behaviour. This in turn reflects the similarities and subtle differences of learner behaviour, which are further analysed in more detail. Building awareness about the learner’s behaviour is the first and necessary step for future learning-aware applications.

[publication] Using Cloud Services in a Modern Learning Management System

Our publication „Using Cloud Services in a Modern Learning Management System“ as part of a Special Issue of the Journal of Computing and Information Technology (CIT) has been published online.
Abstract:

LMS (Learning Management Systems) today are being widely used in almost every educational facility. In the last years all conceivable use cases that need to be carried out by such LMS have been defined and the features a modern LMS needs to offer are very clear. Rarely do we find something a teacher or student needs that an LMS cannot offer. So the task for LMS developers shifted from offering all tools a teacher or student needs to make these tools as convenient to use as possible. Our goal in this research work is to describe the web services we use in TeachCenter, an LMS that has been widely used for the past years at Graz University of Technology to simplify the use of certain components. It can be pointed out that cloud services have to be an integral part of a modern LMS.

[publication] Leveraging Learning Analytics in a Personal Learning Environment using Linked Data

Our publication about „Leveraging Learning Analytics in a Personal Learning Environment using Linked Data“ for the Bulletin of the Technical Committee on Learning Technology is now online available.
Abstract:

We report on the reflection of learning activities and revealing hidden information based on tracking user behaviors with Linked Data. With in this work we introduce a case study on usage of semantic context modelling and creation of Linked Data from logs in educational systems like a Personal Learning Environment (PLE) with focus on reflection and prediction of trends in such systems. The case study demonstrates the application of semantic modelling of the activity context, from data collected for over two years from our own developed widget based PLE at Graz University of Technology. We model learning activities using adequate domain ontologies, and query them using semantic technologies as input for visualization which serves as reflection and prediction medium as well for potential technical and functional improvements like widget recommendations. As it will be shown, this approach offers easy interfacing and extensibility on technological level and fast insight on trends in e-learning systems like PLE.
