EVA: an interactive Web-based collaborative learning environment

In this paper, a Web-based learning environment developed within the project called Virtual Learning Spaces (EVA, in Spanish) is presented. The environment is composed of knowledge, collaboration, consulting and experimentation spaces as a collection of agents and conventional software components working over the knowledge domains. All user interfaces are Web pages, generated dynamically by servlets and agents. Each EVA host has an agent associated with it, which can establish links with the other EVA hosts forming shared knowledge and collaboration space of EVA. The article focuses on the description of the system architecture, implementation of particular software modules, and the application results. A companion article describes current EVA applications in the M. Sc. program in Computer Science.
