In this project, our goal is do develop a calligraphic CAI system which has equivalent abilty to an expert calligrapher. We have investigated the following two topics.(1) A representation method for the calligraphic rules.In the calligraphic CAI system, it must have calligrahic rules for pointing out the mistakes in the chinese characters written by students. We proposed a representation method for the calligraphic rules. We pick out the calligraphic primitives by the conversation procedure between calligrapher and student. The calligraphic rules are represented with a set of the calligraphic primitives.(2) A student model and pedagogical strategy.Considering the difference between calligraphic rules from the model characters and mistaken calli-graphic rules from the student characters, we classify the skill, mastered by student, as follows ;(i) The rules which the student masters correctly : the rules are included in the both calligraphic rules(ii) The rules which the student mistakes : the rules are included in only student character.(iii) The rules which the student doesn't know : the rules are included in only model character.In the proposed method, the student model is defined as the three set of the mastered skill by student.What is important for effective learning is not to learn all mistaken rules, but to learn a part of mistaken rules incrementally. We proposed a method for making pedagogical strategy using the student model as mentioned above. The pedagogical strategy is as follows.(i) Extracting mistaken rules from student model.(ii) Making the aim of a lesson from the priority to be learned.(iii) Showing an appropriate character for mastering the aim of a lesson.
