<\/a><\/p>\nAbstract<\/h4>\n\nThis PhD is in the context of the \u00ab e-Fran \u00bb national project called ACTIF and deals with the design of pen-based intelligent tutoring system for geometry learning in middle school, called IntuiGeo. The contribution of this work are grouped into two axis.
\nThe first axis focused on the design of a recognition engine capable of on the fly interpretation of Han-drawn geometrical figures. It is based on a generic grammatical formalism, CD-CMG (Context Driven Constraints Multiset Grammar). The challenge being to manage the complexity of the real-time analysis process, the first axis of this work consisted in extending the formalism, without losing its generic aspect.
\nThe second axis of this work addresses the tutorial aspect of our system. We define au author mode where the tutor is able to generate construction exercises from a solution example drawn by the teacher. The problem specific knowledge is represented by a knowledge graph. This representation enables the tutor to consider all possible resolution strategies, and to evaluate the pupil\u2019s production in real-time. Furthermore, we define an expert module, based on a dynamic planning environment, capable of synthesizing resolution strategies. The tutoring system is able to generate guidance and corrective feedbacks that are adapted to the pupil\u2019s resolution state. The results of our experiment conducted in class demonstrate the positive pedagogical impact of the system on the pupils performance, especially in terms of learning transferability between the digital and traditional support.<\/p>\n
