To enhance users' social embedding within learning networks, we propose to establish ad hoc transient communities. These communities serve a particular goal, exist for a limited period of time and operate according to specific social exchange policies that foster knowledge sharing. This paper explores the theoretical underpinnings of such communities. To(More)
Recommender systems for e-learning demand specific pedagogy-oriented and hybrid recommendation strategies. Current systems are often based on time-consuming, top down information provisioning combined with intensive data-mining collaborative filtering approaches. However, such systems do not seem appropriate for Learning Networks where distributed(More)
A challenging topic in computer-based education is to develop authoring tools that support the creation of personalized learning designs that, on one hand, do not prescribe any learning approach and, on the other, guarantee the reusability and exchangeability of those learning designs. In this paper we argue that Adaptive Educational Hypermedia Systems(More)
Nowadays, we witness a surge of online profiling sites; in them people make their profile available to others with the intention to share it and get in touch with others, find old friends, classmates or colleagues, or look for new opportunities.

Formative feedback can provide information about how learners develop their competences in a knowledge domain. This information can determine learners' progress and is essential in suggesting remedial actions which overcome gaps in knowledge. Finding this information, however, is a time consuming task. This paper elaborates the theoretical background of(More)

One aspect that has an influence on, and is influenced by these dynamics is the social capital of a community. Features of social capital are the social network structure, the sense(More)
