 abstract = {Evaluating online discussions is a complex task for educators. Infor-mation systems may support instructors and course designers to assess the qual-ity of an asynchronous online discussion tool. Interactivity on a human-to-human, human-to-computer or human-to-content level are focal elements of such quality assessment. Nevertheless existing indicators used to measure inter-activity oftentimes rely on manual data collection. One major contribution of this paper is an updated overview about indicators which are ready for automat-ic data collection and processing. Following a design science research approach we introduce measures for a consumer side of interactivity and contrast them with a producer’s perspective.

Evaluating online discussions is a complex task for educators. Infor-mation systems may support instructors and course designers to assess the qual-ity of an asynchronous online discussion tool. Interactivity on a human-to-human, human-to-computer or human-to-content level are focal elements of such quality assessment. Nevertheless existing indicators used to measure inter-activity oftentimes rely on manual data collection. One major contribution of this paper is an updated overview about indicators which are ready for automat-ic data collection and processing. Following a design science research approach we introduce measures for a consumer side of interactivity and contrast them with a producer’s perspective. For this purpose we contrast two ratio measures ‘viewed posts prior to a statement’ and ‘viewed posts after a statement’ created by a student. In order to evaluate these indicators, we apply them to Pinio, an innovative asynchronous video discussion tool, used in a virtual seminar.

This paper is a report on the findings of a study conducted on the use of the social networking service NING in a cross-location e-learning setting named “Net Economy”. We describe how we implemented NING as a fundamental part of the setting through a special phase concept and team building approach. With the help of user statistics, we examine the value of the implemented social networking service with regard to the need for a social presence, as emphasized by the Community of Inquiry framework. Findings indicate that NING led to a well-meshed network of relationships among the students from the participating locations and that the development of these relationships was fundamentally influenced by the chosen phase concept and team building approach. Further, we show that with the help of social networking services, interconnections between students in virtual teams become more transparent and can be influenced systematically.
