[publication] Is Twitter a Tool for Mass-Edcuation?

My publication about “Is Twitter a Tool for Mass-Education?” at this year S-ICT conference in Vienna is now online available. The slides have been already published here.
Abstract:

Teaching as well as attending lectures in big lectures halls is an often-usual situation in middle European universities. Bearing in mind that a huge mass of learners leads to a decrease of lecture-student interactivity during lectures, the research work aims to enhance traditional face-to-face teaching by technology. The well-known and widely usedmicroblogging platform Twitter is used to display questions, notices and ideas on a wall just in time. Therefore a so-called TwitterWall is developed by Graz University of Technology concerning special pedagogical needs. Afterwards a first use in a big lecture is pointed out and discussed. The publication concluded that the use of Twitter in combination with specifics oftware can help to enhance lecture interactivity in mass-education.

[publication] A Qualitative Approach towards Discovering Microblogging Practices of Scientists

Our this year publication on “A Qualitative Approach towards Discovering Microblogging Practices of Scientists” for ICL 2011 conference is now online avaible as Draft version. The slides were already published here.
Abstract:

Although Microblogging (for instance Twitter) is still rather young compared to other traditional weblogging services there already exists quite a number of studies on itsusage. The majority of scholars dealing with this topic have chosen a quantitative approach focusing on different aspects such as publishing patterns, follower patterns, publishing practices, etc. However, there are less qualitative evidence and case studies on how Twitter is used by adults in their personal working practices. This paper presents a qualitative approach of discovering microblogging practices and obtaining rich descriptions of few cases that give a deeper insight into how Twitter isused by scientists and how this practice shapes their social networks. The methodological approach is based on online ethnographic studies. ThereforeGrabeeter, a tool for collecting all public tweets of a person in various formats, hasbeen adapted in order to obtain the data appropriate for a qualitative analysis following a grounded theory approach. After an analysis of the current state-of-the-art we will outline an approach for a more qualitative analysis that focuses on discovering tacit aspects of microblogging practices such as value or purpose. Finally some initial results from four individual cases will be discussed. This work presentsthe initial phase of a detailed qualitative approach towards exploring microblogging practices of scientists.

[publication] The Integration of Aspects of Geo-Tagging and Microblogging in m-Learning

Our article on “The Integration of Aspects of Geo-Tagging and Microblogging in m-Learning” is now published in the book “Media in the Ubiquitous Era: Ambient, Social and Gaming Media“. A draft version of the article is online available:
Abtract:

The recent years have shown the remarkable potential use of Web 2.0 technologies in education, especially within the context of informallearning. The use of Wikis for collaborative work is one example for the application of this theory. Further, the support of learning in fieldsof education, which are strongly based on location-dependent information, may also benefit from Web 2.0 techniques, such as Geo-Tagging and m-Learning, allowing in turn learning in-the-field. This chapter presents first developments on the combination of these threeconcepts into a geospatial Wiki for higher education, TUGeoWiki. Our solution proposal supports mobile scenarios where textual data andimages are managed and retrieved in-the-field
as well as some desktop scenarios in the context of collaborative e-Learning . Within this scope, technical restrictions might arise while adding and updating textual data via the collaborative interface, and this can be cumbersomein mobile scenarios. To solve this bottleneck, we integrated another popular Web 2.0 technique into our solution approach, Microblogging.Thus, the information pushed via short messages from mobile clients or microblogging tools to our m-Learning environment enables thecreation of Wiki-Micropages as basis for subsequent collaborative learning scenarios.

[video] Can I be your friend?

Hm – eigentlich ist das ein Werbevideo, aber ich denke das soll mal sekundär sein. Spannend ist für mich diese Art der Sichtbarkeitmachung unserer sozialen Netzwerken – also zurücklehnen, genießen und ein klein wenig ausharren zum Nachdenken:
