[publication] The Benefits of Geo-Tagging and Microblogging in m-Learning: a Use Case

Our publication „The Benefits of Geo-Tagging and Microblogging in m-Learning: a Use Case“ of this year MindTrek 2009 conference is online available.
Abstract:

The recent years have shown the remarkable potential use of Web 2.0 technologies in education, especially in the context of informal learning. The application of Wikis for collaborative work is one example for this theory applied. The support of learning in those fields of education, which are strongly based on visual location-based information, could also benefit from Geo-Tagging, a technique that has become popular lately. This paper presents first development results on the combination of these two concepts into a geospatial Wiki for higher education, TUGeoWiki. Our solution proposal supports mobile scenarios where textual data and images are managed and retrieved during m-Learning in- the-field as well as some desktop scenarios in the context of collaborative e-Learning. Within this scope, one critical issue arises while adding and updating textual information via the collaborative interface, which can be cumbersome in mobile scenarios. To solve this problem, we integrated another popular concept into our solution approach, Microblogging. Thus, the information pushed via short messages from mobile clients or microblogging tools to our m-Learning environment enables the creation of Wiki-Micropages as basis for subsequent collaborative learning scenarios.

[publication] Personal Learning Environments for Higher Education: A Mashup Based Widget Concept

Our paper about “Personal Learning Environment for Higher Education – A MashUp Based Widget Concept” within the MUPPLE 09 Workshop at this year ECTEL conference is now online available (presentation).
Abstract:

Due to the enormous growth of distributed applications, services, tools and resources, it is not easy for end users to come across existing services, manage and use them in a matter which is customized according to their personal needs. Mashups can be a very interesting approach to overcome challenges of distributed (unknown) services. Using mashups in a Personal Learning Environment (PLE) can help to connect resources and applications in one environment customized to the needs of individual users. In this paper a first approach and the concept of a PLE especially for higher education is described. The technological concept is introduced and design issues are pointed out as well as the first prototype is described.

[publication] Social networking in scientific conferences – Twitter as tool for strengthen a scientific

Our publication about „Social networking in scientific conferences – Twitter as tool for strengthen a scientific“ for this Science 2.0 for TEL Workshop at ECTEL conference is now online available.
Abstract:

Twitter is the fastest growing member community of the last year. With a rate of 1382% it grows 6 times faster than for example the world biggest social networking application Facebook. In this paper we ask how Twitter can serve as resource at scientific conferences and support the scientific community. Furthermore we ask if Twitter ads any scientific value to conferences. We chose this year ED-MEDIA conference as example for the use of Twitter at a scientific conference and show how the micro-blogging tool got seamlessly integrated in the well-known communication infrastructure of conferences.

[publication] Personal Learning Environment – A Conceptual Study

Our publication about „Personal Learning Environment – A Conceptual Study“ at the Special Track on „MashUps for Learning (MASHL09)“ within the ICL 2009 conference is now online available.
Abstract:

The influence of digital technologies as well as the World Wide Web on education rises dramatically. In former years Learning Management Systems (LMS) were introduced on educational institutes to address the needs both their institutions and their lecturers. Nowadays a shift from an institution-centred approach to a learner- centred one becomes necessary to allow individuality through the learning process and to think about learning strategies in general. In this paper a first approach of a Personal Learning Environment (PLE) is described. The technological concept is pointed out as well as a study about the graphical user-interface done at Graz University of Technology (TU Graz). It can be concluded that PLEs are the next generation environments, which help to improve the learning and teaching behaviour.

Interest on article „How People are Using Twitter during Conferences“

Amazing, our article as well as our presentation „How People are Using Twitter during Conferences“ gathered much more interest as ever expected.
There was a big report on Read/Write Web a month ago „Study Reveals High Levels of Twitter Use at Conferences“ and our presentation on slideshare reached the „Hot on Facebook“

How People are using Twitter at Conferences is being talked about on Facebook more than any other document on SlideShare right now. So we’ve put it on the homepage of SlideShare.net (in the „Hot on Facebook“ section)

as well as the „Hot on Twitter“ list:

How People are using Twitter at Conferences is being tweeted more than any other document on SlideShare right now. So we’ve put it on the homepage of SlideShare.net (in the „Hot on Twitter“ section)

Thanks to all who were and are interested in our research and keep us motivated to do further work.

[publication] Will Personal Learning Environments Become Ubiquitous through the Use of Widgets?

Our publication „Will Personal Learning Environments Become Ubiquitous through the Use of Widgets?“ for this year i-Know Conference is now online available.
Abstract:

Nowadays Personal Learning Environments (PLEs) are described as the use of different social software tools for learning and teaching. The use of common web browsers often is a precondition to fulfil the requirements of social software tools. In this publication a new perspective as well as a couple of prototypes is presented to allow a more independent solution in this context. Using the new JavaFX technology so called widgets are implemented which can be used on different devices as well as different operating systems. Furthermore also the web browser can be replaced by a browser instance. It can be summarized that through the use of widgets the learning environment of the future can be more individualized and personalized.

[review] Tweet, Tweet , Retweet: Conversational Aspects of Retweeting on Twitter

Danah Boyd, Scott Golder und Gilad Lotan sind der Frage nachgegangen, wie Personen sogenannte Retweets auf Twitter verwenden. Also warum dupliziert jemand auf Twitter eine Nachricht und welche Form hat diese dann. Der Artikel selbst erscheint erst in den Proceedings of HICSS-43 im Jänner 2010, trotzdem findet man ein PrePrint Version vorab im Netz:

Tweet, Tweet, Retweet: Conversational Aspects of Retweeting on Twitter

Nun neben einer relative großen Datenanalyse von von fast 720.000 tweets (erste Studie) und 203.371 tweets (zweite Studie) erfolgte auch eine Kurzumfrage. Die wesentlichsten Aussagen sind m. E.:

  • 36% der tweet waren ein reply (@), 5% der tweets hatten einen hashtag (#), 22% der tweets enhielten eine URL und 3% der tweets waren ein retweet (wobei 88% ein RT inkludierten und nur 11% „via“)
  • 52% der retweets enthielten eine URL und 18% einen hastag (#)

Es wird auch aufgezeigt, dass es verschiedene Arten von Retweets gibt und dass sich hier noch keine wirkliche Norm eingebürgt hat. Genauso sehen es die Autoren bei der Analyse warum jemand etwas retweetet. Es werden hier etliche Gründe angeführt:

  • um den Inhalt eines Tweets weiter zu verbreiten und seinen eigenen Followern mitzuteilen
  • um den Originaltweet zu kommentieren und damit eine Diskussion anzuregen
  • um jemanden seiner Community sichtbarer zu machen
  • um jemanden zuzustimmen
  • als eine Art freundschaftliche Geste
  • um eigene Followers zu gewinnen
  • um den Tweet bei sich abzulegen

Auch bei der Frage was denn retweetet wird, kann aufgezeigt werden, dass es primär dann erfolgt wenn man glaubt, dass es für seine Community relevant bzw. wichtig ist – oder aus einer sozialen Aktion heraus. Die Autoren verweisen zum Schluss auch noch auf die Gefahr, dass durch die Beschränkheit der Zeichenanzahl es durchaus zu einer Sinnveränderung des Original Tweets kommen kann und auf weitere Effekte wie die Bitte nach einem Retweet oder ein Ego-Retweet (Retweet eines Tweets in dem man selbst schon vorkommt).
Alles in allem kann, fasst dieser Artikel das Phänomen Retweet auf Twitter sehr gut zusammen und ich kann ihn allen jenen weiterempfehlen, die sich damit näher beschäftigen. Für einen erfahrenen Twitterexperten verbirgt sich eigentlich wenig Neues, zeigt also die gelebte alltägliche Praxis auf.

[publication] Interactive Technology for Enhancing Distributed Learning: A Study on Weblogs

Our contribution to this year HCI 2009 conference about „Interactive Technology for Enhancing Distributed Learning: A Study on Weblogs“ is now online available.
Abstract:

In this study, it was investigated whether, and to what extent, Web 2.0 technologies, actually Weblogs, can be a suitable instrument for enhancing the practice of distributed learning. In educational settings, which are based on traditional lectures many students begin serious study shortly before the exam. However, from previous empirical research, it is known that the practice of distributed learning is much more conducive to retaining knowledge than that of massed learning. A 2*2 factorial design (within – repeated measures) with pre-test and post-test in a real life setting was applied; the study lasted for the whole summer term 2007. Participants were N=28 computer science undergraduates of Graz University of Technology. We randomly assigned them to two groups of equal size: The experimental group given the Weblog treatment are referred to as Group W; whereas the control group with no access are referred to as Group C. Students of group W were instructed to use the Weblog for developing their paper and studying during the lecture and they were requested not to reveal their group affiliation. The results showed that performance scores of group W were significantly higher than that of group C. This demonstrates that Weblogs can be an appropriate instrument to supplement a classical lecture in order to enable deeper processing of information over a longer period of time, consequently resulting in enhanced learning performance.
