A Fundamental Research for Calligraphic CAI System Utilizing Kowledge Engineering

在这个项目中，我们的目标是开发一个具有相当于专家书法家能力的书法计算机辅助教学系统。(1)书法规则的表示方法。在书法计算机辅助教学系统中，必须有书法规则来指出学生书写的汉字的错误。提出了一种书法规则的表示方法。我们通过书法家与学生之间的对话程序挑选出书法基元。书法规则用一组书法基元来表示。(2)学生模型与教学策略。考虑到书法规则来自楷模字符和错误书法规则来自学生字符的不同，我们将学生掌握的书法技能归类为：(I)学生正确掌握的规则：规则包含在书法规则和书法规则中(Ii)学生错误的规则：规则只包含在学生的汉字中。(Iii)学生不知道的规则：规则只包含在模型字符中。在所提出的方法中，学生模型被定义为学生掌握的三套技能。有效学习的关键不是学习所有错误的规则，而是渐进地学习一部分错误的规则。我们提出了一种利用上述学生模型制定教学策略的方法。教学策略是：(1)从学生模型中提取错误的规则；(2)从学习的优先顺序中确定课程的目的；(3)表现出掌握课程目的的适当品格。

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.
