The Socio-constructive approach applied by the largely used e-Learning platforms tries to give the learners the ability to build their own knowledge by searching, analyzing and discussing information in a collaborative environment. This approach has known a large success. In this paper, we will look to this approach from an emotional point of view. The idea is to understand the emotional dimension of the collaborative tools that allow the realization of Socio-constructive learning activities. To do so, we have chosen to use a 3D learning environment in a, attempt to understand the link to the isolation emotion which is generally expressed in text-based environments. The main idea is to prove the presence of an emotional dimension in every component of e-Learning platform. If proven, this affirmation could help us to define new design approaches that exploit this emotional dimension and don't need additional emotion-dedicated components.
