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)
This article argues that the TENC ePortfolio definition should integrate rhetorical, pedagogical, social, and technical perspectives. The rhetorical perspective is needed to show the learner´s competences, achievements and history; the pedagogical perspective aims at supporting learner´s self-reflection, through the definition of competences mastered,(More)
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)

Lifelong learners who select learning activities to attain certain learning goals need to know which are suitable and in which sequence they should be performed. Learners need support in this way-finding process, and we argue that this could be provided by using Personalised Recommender Systems (PRSs). To enable personalisation, collaborative filtering(More)
In online learning, communities can help to enhance learning. However, because of the dynamic nature of communities, attaining and sustaining these communities can be difficult. 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)
Learners, particularly lifelong learners, often find it difficult to determine the scope of their expertise. Formative feedback could help them do so. To use this feedback productively, it is essential to then suggest to them the remedial actions they need to overcome the gaps in their knowledge. This paper presents the design considerations of a support(More)
