【摘要】：面对受教育人员的日益增多和师资力量的相对不足，自适应教学系统逐渐发展起来。自适应教学系统中的学生个体在知识背景、能力水平、认知风格等方面存在着很大的差异。因此，要构建自适应教学系统必须弄清楚学生的能力与差异，方可建立起可操作的、合理的、个性化的学生模型，这是本文研究的重点。本文取得的研究成果主要有以下几个方面：（1）分析了国内外在自适应教学系统和学生模型方面的研究现状，，提出了本研究所要针对的问题，明确了本文研究工作的实用价值与理论意义。（2）在自适应教学系统的理论基础等密切相关的环节上下功夫，力求明确自适应教学系统所依据的教育心理学理论基础，阐明了自适应教学系统所依据的原则。根据本研究的功能需求构建了自适应教学系统的框架。（3）归纳了自适应教学系统中学生模型的特征，明确了学生模型的一般建模方法和学生模型的框架。对学生模型规范、学生模型表示的内容、学生模型要素、学生个性信息、学生模型的自适应导航进行了分析，最后对学生模型进行了设计。本文的创新之处为：（1）利用模糊综合评价法对学生模型中不确定性的因素进行推理，总结出一套完整的构建学生模型的方法，从而为学生模型的实现与更新提供重要的依据。（2）对学生模型进行初始化，探讨了学生模型的更新，对时间、学生学习程度、知识内容、学生掌握的知识值和学生偏好进行更新，为系统的设计提供基础。
[Abstract]:In the face of the increasing number of educated personnel and the relative shortage of teachers, the adaptive teaching system is gradually developed. The students in adaptive teaching system have great differences in knowledge background, ability level, cognitive style and so on. Therefore, in order to build an adaptive teaching system, we must find out the students' ability and difference, and then establish an operational, reasonable and individualized student model, which is the focus of this paper. The research results obtained in this paper are as follows: 1) the research status of adaptive teaching system and student model at home and abroad is analyzed, and the problems to be addressed in this study are put forward. The practical value and theoretical significance of the research work in this paper are clarified. (2) to make clear the theoretical basis of educational psychology on which the adaptive teaching system is based, such as the theoretical basis of the adaptive teaching system and other closely related links, and to make sure that the theoretical basis of the adaptive teaching system is based on the theory of educational psychology. The principle of adaptive teaching system is expounded. According to the functional requirements of this study, the framework of the adaptive teaching system is constructed. (3) the characteristics of the student model of the adaptive teaching system are summarized, and the general modeling method of the student model and the framework of the student model are defined. The specification of student model, the content of student model representation, the elements of student model, student personality information and adaptive navigation of student model are analyzed. Finally, the student model is designed. The innovations of this paper are as follows: 1) using the fuzzy comprehensive evaluation method to infer the uncertain factors in the student model, a complete set of methods to construct the student model is summarized. Therefore, it provides an important basis for the realization and updating of the student model. (2) initializing the student model, discussing the updating of the student model, the time, the degree of study, the content of knowledge, and so on. The knowledge value and students' preference are updated to provide the basis for the design of the system.
