In this research, we study on a world model of an intelligent educational system integrating ITS and ILE.We summarized the relation between ITS and ILE and examined the world model which had to become the point to integrate both systems. In ILE,students deal with the imagery world reflecting the world models of educational systems, while they deal with symbolic knowledge about the domain world in ITS.The domain world model should be able to represent various aspects of the world in both imagery way and symbolic way. We investigate the method of representing the world model from various viewpoint. Using our representation, we can construct world models where the points to which the students should pay attention clarify in the both ways. In order to integrate ITS and ILE,a student model is also important. However conventional researches on student models are mainly dealing with student models in ITS.Therefore we proposed a method of constructing student models by observing students' actions in ILE.We take high-school chemistry as a subject in above researches. It is one of a major subject concerning to a concrete domain world. As an example of a subject concerning to abstract worlds, we take programming. We designed a tool for novice learners of Pascal programming. Programs are written to solve some problems in domain worlds, such as a set of numbers to be sorted, a tree structure representing hierarchical relations among some concepts, and so on. By using the tool, they can see the roles of statements, blocks or routines in their programs, not only on the world of data structures which computers directly handle but also on the above mentioned domain worlds. In the future, we will advance the research to construct a learning environment of integrated educational system for programming.

在本研究中，我们研究了一个集成ITS和ILE的智能教育系统的世界模型。我们总结了ITS和ILE之间的关系，并研究了世界模型，它必须成为整合这两个系统的点。在ILE中，学生处理的是反映教育系统世界模型的意象世界，而在ITS中，他们处理的是关于领域世界的符号知识。领域世界模型应该能够以意象和符号两种方式来表示世界的各个方面。我们从不同的角度探讨了世界模型的表示方法。使用我们的表示，我们可以构建世界模型，其中学生应该注意的点以两种方式澄清。为了整合ITS和ILE，学生模式也很重要。然而，传统的学生模型研究主要是针对智能交通系统中的学生模型。因此，我们提出了一种通过观察学生在英语教学中的行为来构建学生模型的方法。在上述研究中，我们将高中化学作为一门学科。它是涉及到具体领域世界的重要学科之一。作为一个与抽象世界有关的学科的例子，我们以编程为例。我们为Pascal编程新手设计了一个工具。编写程序是为了解决领域中的一些问题，例如要排序的一组数字，表示某些概念之间层次关系的树状结构，等等。通过使用该工具，他们可以看到语句、块或例程在程序中的作用，不仅在计算机直接处理的数据结构世界中，而且在上述领域世界中。在未来，我们将进一步研究如何建构程式设计综合教育系统的学习环境。
