An introduction to e-learning, an overview and its applications is provided by (Holmes & Gardner, 2007). They state that most e-learning didactical models are currently centred on the concept of communal constructivism, which include theories of behaviourism, cognitivism ad socio-constructivism together with the contributions of Bruner, Piaget and Vygotsky. In communal constructivism, each member of the community learns with and from each other as well as contributing resources to the learning community. The key-factor is the provision of enhanced communication and the creation of environments within new understandings can be fostered and developed. In recent years constructivism has extended the traditional focus on individual learning to address collaborative and social dimensions of learning.
