This paper proposes a dialogue based interface for virtual environments of learning with a Multiagent approach. Here, it's shown both aspects involved with the motivation and conception of this interface project, the conceptual and the technological aspect. In the conceptual aspect, the concepts related to distance learning and learning process are presented in the context of interfaces for virtual environment for education. In the technological aspect, it's presented the multi-agent based systems, chatterbots systems and the AIML language applied in the context of the conceptual needs. Finally, based on these concepts and technologies, the paper's contribution is a project for a virtual environment of learning, a middleware architecture based on a multi-agent approach.
