A Java based framework for the development of interactive learning environments based on laboratories containing dynamic geometry applets is presented. DGS applets of different types can be integrated into the same laboratory and interact with each other. The framework can be used to enrich interactive DGS constructions and exercises with automated and semi-automated assessment algorithms and allows recordings of learning processes using a capture & replay software. Two exemplary learning environments based on the framework are presented.
