针对目前辅导行业的现状,为解决课后辅导的自动化、实时化的问题,分析了学生课后学习掌握知识的过程,提出了一个基于学生课后学习规律的辅导模型,建立了面向问题的多层面知识辅导新模式,构建了基于此模式的网络智能家教系统的框架结构.该系统采用基于知识的自动推理技术使得推理过程得以完整保存来分析后续的多层面辅导信息,采用资源模型分解知识粒度保证抽象度,采用网络服务模式满足用户的实时使用.以学生提出的几何问题为实例,展示了多层面辅导过程,实验结果表明了该模式和系统设计的可行性.%Aiming at the current tutoring industry and to solve the problems of automatic and real-time tutorship, students' learning and mastering knowledge progress after class are analyzed. A tutorship model based on the rules of students' learning after class is proposed. A new pattern of multi-level tutorship is designed. Based on this, a framework of the intelligent intemet tutorship system is constructed. In the system, the integrate system reasoning process is saved by adopting the automatic knowledge-based reasoning technique,and make it possible to analyze consequent multi-level tutorship information. Besides, knowledge granularities are decomposed by adopting resource model to ensure abstract degree, and the internet service mode is applied the system to satisfy user real-time needs. Finally,the process of multi-level tutorship for geometry problems proposed by students is provided as an example to demonstrate the feasibility of the pattern and its system design.
