Users usually search for the required information via search engines which contain locations of the information. However. as the amount of data gets large, the result of the search is often not the information that users actually want. In this paper a web guide is proposed in order to resolve this problem. The web guide uses case-based learning method which stores and utilizes cases based on the keywords of user's action and agent's visit. The proposed agent system learns the user's visiting actions following the input of the data to be searched, and then helps rapid searches of the data wanted.

This paper presents web-based virtual laboratory system for electronic and digital circuit experiments. Through our virtual laboratory, the learners will be capable of learning the concepts and theories related to circuit experiments and how to operate virtual experimental equipments such as multimeters, function generators, digital oscilloscopes, DC power suppliers and bread board etc. The proposed virtual laboratory system is composed of important components: Principle Classroom to explain the concepts and theories of electronic and digital circuit operations, Simulation Classroom to provide a web-based simulator to the learners, Virtual Experiment Classroom to provide interactive multimedia contents about the syllabus of off-line laboratory class, Assessment Classroom, and Management System. With the aid of the management System every classroom is organically tied together collaboration to achieve maximum learning efficiency. We have obtained several affirmative effects such as high learning standard, reducing the total experimental hours and the damage rate for experimental equipments.

Web is greatly contributing in providing a variety of information. Especially, as media for the purpose of development and education of human resources, the role of web is important. Furthermore, E-Learning through web plays an important role for each enterprise and an educational institution. Also, above all, fast and various searches are required in order to manage and search a great number of educational contents in web. Therefore, most of present information is composed in HTML, so there are lots of restrictions. As a solution to such restriction, XML a standard of Web document, and its various search functions is being extended and studied variously. This paper proposes a search system able to search XML in E-Learning or var ious contents of non-XML using mobile device PDA.

This research examines how PBL(Problem-based Learning; PBL) system affects to 'Self-directed learning ability', by developing and applying it to the participants of "Science Cyber Conference" - the web based on-line debating learning program - among those students of the Affiliated Institute of Science gifted education of K University, for 16weeks. With this, also the cognizance of learners for the PBL class process are looked into together. After conducting the program applied with the web-based PBL strategy, the participants 'Self-directed learning ability' showed the remarkable change statistically (p<.05). Especially it showed the meaningful changes in six sections (p<.05), among those subdivided seven sections of 'Self-directed learning ability', with the one exception, 'Self-confidence as a Learner'. They also showed the positive response to the class which adopted the web-based PBL strategy.

This paper is preliminary study for developing Web-based instruction material to practice open mathematics education in middle school using Web as educational environment. For this purpose, the (textbook-based) curriculum was analysed and then more flexible and differentiated dynamic (web-based) curriculum was suggested.

Purpose: This study was done to develop a web-based education program on appropriate antibiotic use and test the effects of the program on knowledge and attitudes towards antibiotic use in Korean adolescents. Methods: The web-based education program was developed through an extensive literature review and professional advisory meetings including technical assistance from a web-based education programmer and content experts. A convenience sample of 851 students from middle and high schools participated in the assessment of effects of the program. Knowledge and attitudes of the students towards antibiotic use and satisfaction with the web-based education program were measured. Descriptive statistics and paired t-test were used to analyze the data. Results: There were significant improvements in knowledge and attitudes towards antibiotic use following self-learning via the web-based education program in both middle and high school students. High school students demonstrated higher scores in knowledge and attitudes than middle school students. Conclusion: The results of this study indicate that this web-based education program on appropriate antibiotic use is a convenient and effective medium for self-learning in adolescents. Therefore the web-based program should be put into wide use as an effective and convenient teaching method for health education in secondary schools.

As computer technology is in progress and many educational methods have been emerged, web-based cooperative learning and educational games have gained a lot of interests. Some cooperative learning systems and game-based educational systems have been suggested, but few cooperative learning systems use games. This paper builds a new web-based cooperative learning system using games that enables learners to actively participate and have high interests in learning. In our system, cooperation study is performed in each group and a group member competes with other group members using games. A crossword puzzle game is adopted because of ease to use and fit with cooperative learning scenarios. Our suggested system is implemented and used by two classes of high school students to evaluate this system. The experimental results show that our system effectively improve students' learning interests and increase their academic achievement.

Recent changes in medical environment are based on technology such as internet. As most hospitals require the change and the adaptation of medical, medical information experts are more needed. In this study, we developed web based PBL model and applied it to the students majoring in medical information system. The developed web-PBL model focuses on learner's online learning activities to enhance collaborative learning and self-directed learning by using online learning tools. At the result of the research, We found that the students' course evaluation somewhat increased compared to the previous class and the students positively perceived on PBL model. Moreover, this study showed that using blog as a online learning tool was a good way to enhance cooperative learning.

In this Paper, we Propose an efficient web-based video learning evaluation system that is tailored to individual student's characteristics through the use of user profile-based information filtering. As a means of giving video-based questions, keyframes are extracted based on the location, size, and color information, and question-making intervals are extracted by means of differences in gray-level histograms as well as time windows. In addition, through a combination of the category-based system and the keyword-based system, questions for examination are given in order to ensure efficient evaluation. Therefore, students can enhance school achievement by making up for weak areas while continuing to identify their areas of interest.

A user can use resources on the Semantic Web using a Semantic Web browser. In order to utilize the functions of Semantic Web browsers in education, we compared the functions of well-known Semantic Web browsers such as Tabulator, Contextual Search Browser (CSB), Magpie, and Piggy Bank. In order to utilize Semantic Web browsers in education, a user needs to understand the features of each Semantic Web browser and our work can help both teachers and students. Tabulator is an RDF browser that can help to check whether resources can be used for learning and relevance of resources. CSB can be used to search educational resources using a conrtext file that contains the subjects of learning. It can also help learning by showing semantic web resources in the form of triple set as well as by supporting highlighting function. Magpie can help learners without basic knowledge on learning materials by providing interpretation based on a glossary file and related background knowledge. Piggy Bank supports conversion of web resources into semantic web resources and allows to browse semantic web resources in various views as well as to share semantic web resources.
