本文提出了基于知识的实体关系建模智能导师KERMIT。KERMIT是一个面向大学水平学生的问题解决环境，他们可以在其中使用实体-关系数据模型练习概念数据库设计。KERMIT使用基于约束的建模（CBM）对领域知识建模并生成学生模型。我们以前在教授SQL和英语标点规则的导师中使用过CBM。本文中提出的研究是重要的，因为我们表明CBM可以用来支持学生学习设计任务，这与我们在早期导师中处理的领域非常不同。介绍了系统的结构和功能。该系统观察学生的行为，并与他们的知识和学习能力相适应。KERMIT已经在真实的教学活动中进行了评估。我们提出了两项对数据库课程学生的评估研究结果，表明KERMIT是一个有效的系统。学生们很喜欢这个系统的适应性，并发现它是他们学习的宝贵财富。
The paper presents KERMIT, a Knowledge-based Entity Relationship Modelling Intelligent Tutor. KERMIT is a problem-solving environment for the university-level students, in which they can practise conceptual database design using the Entity-Relationship data model. KERMIT uses Constraint-Based Modelling (CBM) to model the domain knowledge and generate student models. We have used CBM previously in tutors that teach SQL and English punctuation rules. The research presented in this paper is significant because we show that CBM can be used to support students learning design tasks, which are very different from domains we dealt with in earlier tutors. The paper describes the system's architecture and functionality. The system observes students' actions and adapts to their knowledge and learning abilities. KERMIT has been evaluated in the context of genuine teaching activities. We present the results of two evaluation studies with students taking database courses, which show that KERMIT is an effective system. The students have enjoyed the system's adaptability and found it a valuable asset to their learning.
