  • The increasing demand for the distance learning has created a need to explore the implications of the emerging paradigm shift in the learning environment. For the use of information technology to improve learning processes, the pedagogical assumptions underlying the design of information technology for educational purposes must be understood. However, little theoretical development or empirical research has examined learning effectiveness in web-based distance learning. Thus, this paper reviews from research in management communications, education, social psychology, and information systems literatures to develop an conceptual model of influences on web-based corporate education outcomes. The hypotheses empirically examined using survey data from 152 students of 'L' company. The data support the validity and reliability of our constructs. And the hypotheses of this study get partially significant support. Finally, the implications of this survey results are discussed in terms of learning performance.

  • Operating Systems is a discipline which handles complex and concepts related to its components and how an operating system works. However, most of the OS courses have been textbook-oriented theoretical classes. Therefore, many instructors have tried to make use of educational tools to help students understand a lecture and arouse their interests consistently. This paper describes the design and implementation of a web-based page replacement simulator which shows the process of page replacement algorithms visually. The academic achievement evaluation and t-test results for 2010's students and 2011's show that the differences of the correct answer ratios for the exam about page replacement algorithms and the scores between two groups are meaningful. And the results of survey show that a page replacement simulator is useful as an educational tool which causes the interests about operating systems and enhances the understanding of a lecture.

  • The explosive growth of Web-based educational resources requires a new approach for accessing relevant information effectively. Social searching in the context of social navigation is one of several answers to this problem, in the domain of information retrieval. It provides users with not merely a traditional ranked list, but also with visual hints which can guide users to information provided by their colleagues. A personalized and context-dependent social searching system has been implemented on a platform called KnowledgeSea II, an open-corpus Web-based educational support system with multiple access methods. Validity tests were run on a variety of aspects and results have shown that this is an effective way to help users access relevant, essential information.

  • Human-Robot Interaction (HRI), based on already well-researched Human-Computer Interaction (HCI), has been under vigorous scrutiny since recent developments in robot technology. Robots may be more successful in establishing common ground in project-based education or foreign language learning for children than in traditional media. Backed by its strong IT environment and advances in robot technology, Korea has developed the world's first available e-Learning home robot. This has demonstrated the potential for robots to be used as a new educational media - robot-learning, referred to as 'r-Learning'. Robot technology is expected to become more interactive and user-friendly than computers. Also, robots can exhibit various forms of communication such as gestures, motions and facial expressions. This study compared the effects of non-computer based (NCB) media (using a book with audiotape) and Web-Based Instruction (WBI), with the effects of Home Robot-Assisted Learning (HRL) for children. The robot gestured and spoke in English, and children could touch its monitor if it did not recognize their voice command. Compared to other learning programs, the HRL was superior in promoting and improving children's concentration, interest, and academic achievement. In addition, the children felt that a home robot was friendlier than other types of instructional media. The HRL group had longer concentration spans than the other groups, and the p-value demonstrated a significant difference in concentration among the groups. In regard to the children's interest in learning, the HRL group showed the highest level of interest, the NCB group and the WBI group came next in order. Also, academic achievement was the highest in the HRL group, followed by the WBI group and the NCB group respectively. However, a significant difference was also found in the children's academic achievement among the groups. These results suggest that home robots are more effective as regards children's learning concentration, learning interest and academic achievement than other types of instructional media (such as: books with audiotape and WBI) for English as a foreign language.

  • Purpose To meet changing social demands and fulfill the needs of the information and communications technology industry, the curriculum of MIS related department should develop and implement new conceptual frameworks. In response, the purpose of this study was to develop curriculum for students in the Department of e-Business at Kyungnam University. Design/methodology/approach We conducted a demands analysis of educational demanders, NCS(National Competency Standards) based curricular analysis, and benchmarking from other management information systems related departments. The expert panel committee consisting of e-Business department faculty members was held to examine and discuss the student-oriented curriculum developed during this study. Findings Results show that the contents and types of curriculum should be organized so that students can maximize their professional job competency to apply to their core professional tasks. Given these findings, we reconstructed the curriculum with both basic and advanced courses, all systematically organized according to the job requirements they offer toward meeting the industry's needs. We also implemented the web-based JSSS(Job Searching Support System) with which educational demanders can search among 13 job types, estimate their performances, and obtain the information about course registration. In all this study presents specific, practical evidence of the job-related curriculum for students in the Department of e-Business at Kyungnam University.

  • In this paper, I discuss the problems of developing web based adaptive hypermedia for education using extensible Markup Language(XML). Adaptive hypermedia systems are capable of altering the Presentation of the contents of the hypermedia on the basis of a dynamic understanding of the individual student. The student profile is contained in a student model, while the knowledge about the domain can be represented in the form of a concept based domain model. Accordingly, I define two different markup languages using XML. The one structures the domain model and the another describes the student model. These language can be easily extended and authored, with the result of obtaining a simple methodology for data structuring in the field of web based educational adaptive hypermedia.

  • Most of the existing algorithms try to disseminate the multimedia contents of internet service provider(ISP), without taking into account the needs and characteristics of specific websites including e-learning systems with web-based .educational contents. Sometimes the client must select the best one among the replicated repositories. However, this is a less reliable approach because clients' selections are made without prior information on server load capacity. In this paper we propose an agent system inspired by the need of improving QoS of delivering web-based educational multimedia contents without incurring long access delays. This agent system consists of three components, Analyzer, Knowledge Base, and Automaton embedded the capacity algorithm. It analyzes and investigates traffic information collected from individual replicated server by learners' requests, and selects a server which is available and is expected to provide the fastest latency time and the lowest loaded capacity, and achieves high performance by dynamic replicating web resources among multiple repositories.

  • As web technology and educational environments are in rapid progress, web-based cooperative learning systems have gained a lot of interests. Recently some studies have attempted to combine a learning system and simple games that enable learners to actively participate and have high interests in learning. These studies are based on TGT model, a cooperative learning model using games, and mostly remain system design levels. A few implemented systems have many problems because they focus only on pure TGT model. To solve these problems, this paper builds a extended TGT model and a new web-based cooperative learning system using this new model. The extended part contains ideas such as expert learning from Jigsaw II model, improvement scores from STAD model and making game problems by learners. A system using pure TGT model and a suggested system are implemented and used by two classes of middle school students to evaluate our system. The experimental results show that our system outperforms the other system.

  • Web based learning has been used for many educational systems by aid of the development of internet technique. The true process of education includes not only learning contents but also learning process and the evaluation. So far, Web-based evaluation mainly consists of the evaluation of the learning products or the evaluation of the cognitive domain. But, there is lack of the appropriate feedback for learning effects. In this paper, we design and implement an evaluation system for Web-based instruction. In our system, the learners are evaluated during the process of Web-based learning. Our system provides learner-centered instruction for students with instant feedback. The questions made up by teachers are stored in the database and can be searched by a keyword, grade, semester or unit. The evaluation system can also provide the feedback to right or wrong answer for each question. Our system provides the learners with instant feedback after solving the questions and also can improve the quality of learning process using the Web.

  • In the distance education systems, there are limited things while performing educational activities because there are to be problems in structural features of the Web. HTTP, a connection-less protocol, performs requests of client, however, does not hold on the status. Thus, by features of the Web, it is difficult to hold on the connection of learners and trace information asked by learners. Moreover, these problems make impossible not only a learner's connection continuity but also on-line interaction among the learners in the distance education. This thesis developed CHTP, an connection-based hypertext transfer protocol, based on HTTP and a new platform of distance education in order to track activities of learners. The developed web extension platform will make it easy to build up system for being helpful in a distance education because this thesis proposes a standardized way in the protocol.
