Special Issue on Visual Aspects in Technology Enhanced Learning

Technology Enhanced Learning (TEL) is growing towards the integration and support of a variety of tools and technologies, related to learning and teaching activities: authoring tools for learning objects, management and evaluation of the relations holding among the learning objects collected in a repository, management of student models, multifaceted interaction with instructional material, the delivery of practical learning experiences and management of their assessment. This growth extends, nowadays, towards game-based and social-collaborative e-learning, allowing to extend the range of pedagogical approaches tackled in TEL. In parallel with this evolution, the “aspects” related to the visualization of information are growing steadily, in both importance and complexity. They, basically, allow to make conscious use of the variously faceted amount of information collected in a learning system, such as the content of student models, the activity logs, or the performance representation.
