In recent years, parents of students and government have been taking a growing interest in education for the gifted students and there are many research reports about the gifted education. Most of the reports, however, focuses on the conceptional feature of the gifted education program such as organization, operation, management, evaluation, etc,. In other words, there are very few researches on instructional materials for gifted students even though the materials is a critical factor for successful education programs. So, this paper introduces a lecture notes used in a personal education for gifted students to contribute in developing education contents in computer science area. The instructional materials titled as "The Necessity and Application of Matrix in Computer Science" is based on linear equation to usher the students into creative problem recognition and groping for solutions. Also, the instructional materials is useful for students to understand the tight mathematics-computer science relationship and the basic concept of liner algebra.

The recent advances of the information technology have motivated lots of research efforts to develop new computer-aided teaching and learning methodologies on various computer science topics, such as data structures, operating system, computer networks, and computer architecture. However, there have been only few studies to educate the database subject although it is one of the most important topics in the computer science. Specifically, among the various issues in the database subject, a learner often suffers to understand the mechanism of the concurrency control and recovery of database transaction in the database because it highly interacts with other functions in the database. Obviously, an intelligent visualization tool can help a learner to understand the process of the concurrency control and the recovery of database transaction. The purpose of this study is to develop an efficient visualization tool which can help users understand the two phase locking protocol (2PLP)-based concurrency control. Specifically, this visualization tool is designed to encourage a users' participation and raise their interest by visualizing the process of transactions and allowing users to specify and manipulate their own transactions.

This study aimed to analyze the level of professors' understanding and perception of adaptive learning and proposed how college can implement successful adaptive learning in college classes. For research purposes, online survey was conducted by 162 professors of A university in capital region. As a result, professors seemed to feel pressure to provide students personalized feedback and gave concerned that students don't study enough in advance before participating in class. It was also found that professors realized that they have low level of understanding about adaptive learning, while they revealed intention to make use of adaptive learning in their class. They also answered that adaptive learning system is the most helpful support for encouraging professors to apply adaptive learning in real class. We proposed what is required to encourage professor to implement adaptive learning in their class.

Development of Learning system and learning activity based on web in accedence with development of information communication technology are active. From teaming system with web, teaching-teaming data for student's leaning level is not systematic and interactions between students and teachers are insufficiency. Only result of teaming evaluation is showed not supply reason what is correct or not and there is no relationship or linking deeping teaming. In this paper, we tried to improve the interaction between teachers and students by analyzing study system through virtual system on high school's Introduction to computer science. And we designed and implemented the WBI system Using ASP, the system is maximize the effect of study related to further study. It will improve the feedback between the teachers and the students and help the learners enlarge the faculty of comprehension ability.

본 논문에서는 on-line을 통한 교육방법의 하나인 e-learning(Web Based Instruction)을 활용한 음악과 수업모형을 개발하여 교육적 활용 효과를 검증하였다. 웹 기반 교수학습 자료를 구축하고 각종 학습 자료를 탑재하여 수업에 활용하였으며, 교육 효과를 보다 정확히 알아보기 위해 수준별(상,중,하) 3개 그룹으로 나누어 e-learning 기법을 적용 사전평가 및 사후평가를 통하여 얻어진 결과를 통계 처리하여 검증하였다. 본 논문에서는 학습자의 능력과 필요에 따라 능동적인 학습이 이루어지도록 하였다. 개별학습, 반복학습 및 자기주도적 학습을 진행할 수 있도록 구성하였으며, 그 결과 구체적이고 실질적인 학습 효과를 얻을 수 있었다. e-learning 활용수업을 실시한 실험 집단 전체에서 off-line 수업을 실시한 통제집단보다 학습 성취도에 있어서 효과적인 것을 확인할 수 있었다. 상위, 중위 그룹의 학생들에게는 웹 기반 교수학습 활용수업이 학습효과에 있어서 큰 차이가 없었지만 하위 그룹의 학생들에게는 크게 효과적인 것으로 나타났다.

Opensource LMS Moodle consists of module of various forms and can mount learning materials of various forms. We can mount the number of contents on the Web in Moodle. In doing so, We can configure effective courses for teaching-learning activity. Moodle can reflect course design of a wide variety of teacher using a variety of learning resources and learning activities. The results of operating during 1 semester, all faculty or students were satisfied with course using Moodle. Class in the classroom is interactive systems of teacher and students, but class has one-way system in reality. E-learning can be used to complement this phenomenon. Moodle gives a free and powerful features in designing e-learning courses. In this reserch we made up course applying typical teaching-learning of design and model the process of Glaser. We analyed teaching - learning activity case of Understanding and Application of Information science course of 2010year 1 semester in Seoul national University of Education using LMS Moodle and pursued future expansion plan of Moodle.

The purpose of this study has been found to be effective using ICT teaching-learning than traditional teaching-learning method on academic achievement applying the meta-analysis method. This study set the following questions to be answered. 1. The 85% subject of analysis of ICT-using teaching-learning selected in this study turned out to be clear effective than traditional teaching-learning method in academic achievement of students. 2. ICT-using teaching-learning is more effective for academic achievement of elementary school students and university students than for middle school students and high school students relatively. 3. ICT-using teaching-learning is a most effective method in subject of art and physical education and social subject but less effective in mathematics subject.

A more interactive teaching-learning system is increasingly necessary in the consumer-oriented environment of distance education. This article would like to suggest a more spontaneous system which is learners at various levels. The suggested system keynotes its efficiency with the introduction of a "mobile agent" concept through which learners are able to network and complete their assignments despite their dispersed environments. This article also suggests some managerial techniques for the systematic management of agent-based learners possessing diverse characteristics. Through this study, we expect more highly effect by offer data adapted to learning goal to learner's ability, get out of uniform web-based teaching-learning.
