In this paper we present ReTuDiSAuth, the authoring tool of the educational system ReTuDiS, as a tool capable to support authors while constructing different versions of texts with text activities in the domain of Informatics, adapted to different learner profiles of text comprehension. Learners are activated to use their background knowledge while reading and more students will have the opportunity to achieve better learning results in learning from texts than reading a single textbook in Informatics targeted at an average reader. © Common Ground, Grammatiki Tsaganou, Maria Grigoriadou.
