Authoring tools for structuring text-based activities

In this paper we present research results and discuss recent directions concerning the structural analysis of science texts and cognitive aspects of text elements, such as causal relationships between text elements. We outline the process of structuring text material for the design of dialogue activities for science text comprehension in the educational environment of ReTuDiS (Reflective Tutorial Dialogue System). The system supports text comprehension using reflective dialogue activities, adapted to learners of different levels and its authoring tool, ReTuDiSAuth, supports users in authoring dialogue activities. © Springer-Verlag Berlin Heidelberg 2007
