Recently, as more web-based applications are widely used, various methods for education are developed in practical areas. As a result, in many organizations, virtual educations such as WBI learning. CAI, and distance learning are offered actively. With the advantages of web-based education, in order to achieve feasible and efficient effects on education. a new web-based instruction model that considers the abilities, the interests, and the aptitudes of students individually is required. In this paper, a new web-based instruction model, called a hybrid model, is proposed and implemented. And then, two model - the stepwise model and the hybrid model- are applied to a computer accounting class of a vocational high school. Students attend the web-based class in a computer center for 100 minutes autonomously. After the classes, a questionnaire is made in order to analyze both the effect on that class and the learning fulfillment of the proposed instruction model.

The effect of Web-based project learning on the science achievement and attitude of middle school students was investigated. Four classes of 9th grade at a coed middle school were divided into control and experimental groups. Web-based project instruction in which students utilized the Web to interactively carry out their projects was put into practice with the experimental group, while traditional instruction was employed with the control group. Pre- and post-test achievement and attitude scores were estimated through an analysis of covariance. Web-based project instruction was seen to be more effective in enhancing students’ science achievement and attitude than traditional instruction. In particular, the former instruction was most useful for improving higher level students’ achievement and attitude among the higher, middle, and lower level students of both groups, based on their academic achievement. The effect of Web-based project may result in eradicating negative cognition about gender difference.

With the advance of computer and communication technologies, a lot of virtual schools provide web-based classes that provide learning environments out of temporal and spatial constraints and many research works on the web-based classes have been proposed. Various techniques are required to build the virtual schools efficiently. One of them is the scheme for transaction management. However, existing transaction management schemes have inappropriate features for supporting web-based classes. In this paper, we propose a new locking-based transaction processing protocol that satisfies the requirements after presenting the requirements for transaction management to support web-based classes. In the protocol, a new method, called mark, is adopted to satisfy the requirements. The proposed protocol also eliminates unnecessary delays or abortions and thus, the proposed protocol can improve the performance of database systems.

The purpose of the study was to investigate how to improve students' information literacy and problem solving abilities in the computer subject. A web-based problem-based learning (PBL) for computer subject for the 8th graders in middle school are designed and developed. In addition. the process of learners' problem solving on problems produced from PBL model was analysed 10 investigate the way how to evaluate learners' responses and products during two semester.

Cooperative web-based learning is an teaching strategy in which small teams, each of students with different levels of ability, use a variety of learning activities to improve their understanding of a subject via the web. The objective of this paper is to propose new assessment items for evaluating students fairly in cooperative web-based learning. As a result, improved academic achievement, improved behavior and attendance, and increased self-confidence can be made in cooperative web-based learning due to the fair assessment, In this paper, the environment and instructional strategies for successful learning are firstly examined. In addition, the existing evaluation items in traditional classroom are also analyzed in order to develop new evaluation criteria in the web. Based on these analyzed items, we propose new evaluation items for cooperative web-based learning. In addition, the proposed items related to participant ratio, cooperability, and accountability are analyzed according to team organization styles and instructional models.

학생들이 스스로 문제를 해결하는데 필요한 과정과 기술을 강조하는 STS 교육의 특징에 비추어 볼 때, 인터넷을 이용하여 의사소통과 정보 수집을 하고 자료를 의미 있게 종합할 수 있는 웹기반 교육을 적용하면 효과적일 것이다. 또한 학생의 창의성이나 문제해결력 등 고등사고 기능을 파악하고 신장시키기 위한 수행평가 또한 STS의 수업 목표를 달성하는데 효과적일 것이다. 이에 일반적인 STS 수업을 적용한 학급과 웹기반 교육의 장점과 수행평가를 가미한 STS수업을 적용한 학급의 학업성취도를 비교 분석하여 STS학습에서 웹기반 수행평가의 효과를 검증하고자 STS 학습을 지원하는 수행평가 시스템을 설계하였다.

In the web- based educational system, how to improve interaction among learners are very important by the Internet. Therefore interpersonal interaction is essential for a good educational environment. In this paper, a web-based PBL(Problem-Based Learning) system is designed and implemented to improve learner's interaction. I investigated how the method for improving interaction affect PBL activities and how students perceive the web-based PBL learning experience. The result of experiment showed that the suggested system facilitated learners' self-directed learning process and interaction.

The purpose of this study is to compare the reading effects of face-to-face reading discussion with those of web-based leading discussion. For doing this, 1 made experimental processes: firstly, to select two discussion methods(face-to-face and web-based) on the reading discussion, secondly to apply each of those methods to experimental groups(2 classrooms, 72 middle school students). The results were that there were no differences from both discussion methods in the understanding the book, in the performance degree on discussion process among higher level groups, but the web-based reading discussion model had an impact on the attitude degree of the reading discussion, the preference degree of reading, the attendance degree of reading discussion, and especially, in the lower level groups, the web-based reading discussion method was better for the attendance degree of leading discussion, the attitude of reading discussion than the face-to-face reading discussion.

The purpose of this investigation was to help university professors for making their systematic design of instruction easily and scientifically. To increase of learner's studying ability, the systemic instructional design is imperative. But most of university professors could not get proper experiences to know develop instructional design system, specially to develop web-based system. This new system made it possible to select the proper instructional methods and the media type suitable for the corresponding data. And also every professor who is involved to know this system, can put informations for the target learners, learning contents and learning objectives, and present the proper media types and the many different conditions in the process of the each instructional design process. Finally, the results of the learner's study will be effective and professors showed their positive opinions for the using of the system.
