Advances in information and telecommunication technology increasingly reveal the potential of computer supported education. However, most computer supported learning systems until recently did not pay much attention to different characteristics of individual learners. Intelligent learning environments adaptive to learner's preferences and tasks are desired. Each learner has different preferences and needs, so it is very crucial to provide the different styles of learners with different learning environments that are more preferred and more efficient to them. This paper reports a study of the intelligent learning environment where the learner's preferences are diagnosed using learner models, and then user interfaces are customized in an adaptive manner to accommodate the preferences. In this research, the learning user interfaces were designed based on a learning-style model by Felder & Silverman, so that different learner preferences are revealed through user interactions with the system. Then, a learning style modeling is done from learner behavior patterns using Decision Tree and Neural Network approaches. In this way, an intelligent learning system adaptive to learning styles can be built. Further research efforts are being made to accommodate various other kinds of learner characteristics such as emotion and motivation as well as learning mastery in providing adaptive learning support.

Der Computer kann ein nutzliches, herausforderndes und kreatives Werkzeug und Hilfsmittel beim Sprachenlernen darstellen. Bei der Anwendung auf die Situation des Grammatiklernens sind die analytischen und interaktiven $F\"{a}higkeiten$ des Computers mit gutem Erfolg eingesetzt worden. Eine der attraktivsten Eigenschaften des Computers ist nun seine $F\"{a}higkeit$, mit dem Schiller zu interagieren. Gute Computerprogramme $erm\"{o}glichen$ eine ausgedehnte Interaktion zwischen Computer und $Sch\"{u}ler$. Die Computerprogramme zum Sprachenlemen befassen sich mit Grammtik. Hier habe ich ein Lemprogramm des Intelligent Tutoring Systems $f\"{u}r$ die Grammatik Perfekt programmiert. Das Intelligent Tutoring System ist ein Computerlehrer. Wenn dem $Sch\'{u}ler$ Fehler unterlaufen, gibt ein guter Lehrer nicht nur die richtige Antwort, sondern hilft dem Schiller auch, seinen Fehler zu erkennen, ihn zu analysieren und zur richtigen Antwort zu finden. Das ist eine Funktion des Intelligent Tutoring Systems. Die Programme geben die Fehlermeldung richtig oder falsch. Dem Schuler werden Aufgaben vorgelegt, die sich aus mehreren Schritten und Prozessen zusammensetzen, wobei der Computer als Werkzeug bei der Suche nach einer $L\"{o}sung$ dient In guten $Probleml\"{o}sungsprogrammen$ verfolgt der Computer den $L\"{o}sungsansatz$ des $Sch\"{u}lers$ und analysiert seine Fehler. Wenn der Schuler bei der $\"{U}bung$ die richtige Antwort $ausw\"{a}hlt$, lauft das nachste Lernprogrammn des Computers. Die $\"{U}bungstyp$ kann auf dem Computer angereichert werden, indem $pr\"{a}zise$ und hilfreiche Kommentare $f\"{u}r$ jede $Auswahlm\"{o}glichkeit$ geboten werden.

This paper describes a novel approach to adaptive courseware generation. This approach adopts its structure from existing intelligent tutoring systems and introduces a new component called pedagogical scenario model to support pedagogical flexibility in the adaptation process of courseware generation system. The adaptation is carried out using Dynamic Constraint Satisfaction Problem framework, which is a variant of classical Constraint Satisfaction Problem, to deliver courseware tailored to individual learner. Such a framework provides a high level of expressiveness to deal with the particular characteristics of courseware generation problem. Further, it automatically designs a sound courseware satisfying the design constraints imposed by the domain, the pedagogical scenario and learner models.

웹 기반 교수 시스템들은 대체로 수동적이며 정적인 하이퍼텍스트 위주이기 때문에, 학습자 개개인의 학습 능력에 따른 적응력 있는 학습 환경을 제공할 수 없다. 본 연구에서는 학습자들의 학습 상황을 효과적으로 파악하고, 학습 결과에 따라 학습자 개개인의 특성에 맞는 동적인 학습 내용을 구성하여 제공할 수 있는 지능형 교수 시스템을 제안한다. 본 시스템은 에이젼트를 기반으로 설계되었으며, 학습을 위한 코스웨어 지식을 효과적으로 구성하여 학습 평가에 따른 적절한 피드백을 추론하여 학습자에게 지원하도록 하고 있다.

The most effective tutoring method is one-on-one, face-to-face in-person human tutoring. However, due to the limited availability of human tutors, computer-based alternatives have been developed. These software based alternatives are called Intelligent Tutoring Systems (ITS) which are used to tutor students in different domains. Although ITS performance is inferior to that of human teachers, the field is growing and has recently become very popular. User interfaces play key role in usability perspective of ITS. Even though ITS research has advanced, the majority of the work has concentrated on learning sciences while mostly disregarding user interfaces. Because of this, the present ITS includes effective learning modules but a less effective interface design. Usability is one approach to gauge a software's performance, while "ease of use" is one way to assess a software's quality. This paper measures the usability effectiveness of an ITS which is designed to teach Object-Oriented (OO) analysis and design concepts using Unified Modeling Language (UML). Computer Supported Usability Questionnaire (CSUQ) survey was conducted for usability evaluation of UML-ITS. According to participants' responses to the system's usability survey, all responses lie between 1 to 3 scale points which indicate that the participants were satisfied and comfortable with most of the system's interface features.

Until now, most Intelligent Tutoring Systems are lacking in the modularity, the extensibility of the system, and the flexibility in the dynamic environment due to the static exchanges of knowledge among modules. To overcome these flexibility in the dynamic due to the static exchanges of knowledge among modules. To overcome these problems, we will suggest, in this paper, a Distance Intelligent Tutoring Framework, called DELFOM, based on the multiagent to cope with the various and complicated learner's requests. We could make different types of learning systems by simply changing the contents of DELFOM External that is variant part of DELFOM. This framework, therefore, provides software reuse and the extensibility based on object-oriented paradigm. And we will propose two different distance learning systems using DELFOM. Therefore this framework gives the developer/the learner the effective and easy development/learning environment. DELFOM is implemented using CORBA and Java for the network transparency and platform independence.

The major limitation of the traditional Intelligent Tutoring Systems (ITS) is that interface is mainly focused on the cognitive factors. However, the new direction of ITS is shifting form the cognitive perspectives to the motivational perspectives reflecting the individual differences. In this study, the specific design guidelines for motivational interface of ITS are proposed to promote learner's motivation to learn during the interaction with the ITS. First, ITS should be able to reflect individual differences in cognitive abilities, interest and motivation, and ongoing changes of the interestingness and comprehensibility during learning activities. Second, it is essential for ITS to guarantee learner controllability, diverse learning activities, curiosity, self-relevance, and challenge to enhance the level of motivation and situational interest. Third, the game-like properties are also needed to maximize the motivational effect of learning with ITS.
