Abstract |
Traditional learning process involves a series of costs related to the resources used and assumes certain restrictions to the lessons because of the way they are planed and deployed. Technological development has allowed the removal of certain restrictions, but it has also led to additional consequences, inexistent in traditional learning. This paper presents an analysis, in terms of costs and resources, which is needed in the implementation and operation of the systems that provide environments for collaborative learning, by highlighting some designed elements that can lead to reduced costs.
