Application developers need effective reuseable methodology to meet rapidly changes and variety of users requirements. Product Line and CBD(Component Based Development) offer the great benefits on quality and productivity for developing the software that is mainly associate with reusable architectures and components in a specific domain and rapidly changing environments. Product line can dynamically focus on the commonality and variety feature model among the products. The product line uses the feature modeling for discovering, analyzing, and mediating interactions between products. Reusable architectures include many variety plans and mechanisms. In case of those architecture are use in product version for a long time, It is very important in architecture product line context for product line design phase. Application developer need to identify the proper location of architecture changing for variety expression. It is lack of specific variety managements to design the product line architecture until nowdays. In this paper, we define various variety types to identify the proper location of architecture changing for variety expression and to design the reusable architecture. We also propose architecture variety on feature model and describe variety expression on component relations. We implemented the web learning system based on the methodology. We finally describe how these methodology may assist in increasing the efficiency, reusability, productivity and quality to develop an application. In the future, we are going to apply the methodology into various domain and suggest international and domestic's standardization.

Elementary school students have a great deal of interest in Internet games which provide integrated multimedia and so they become to know well the terminology used in network such as game server, Internet service, transfer time, etc. In addition, they are used to understand the technological phenomena occurring in internet. They, however, have difficulty understanding concepts and principles regarding the phenomena mentioned above because the educational contents in elementary school computer textbooks consist of only ICT education and its applications, i.e., tool-based technology. In this paper, we apply educational learning on network concepts which are the basis on the internet to classroom instruction by using problem oriented models. We conclude that the educational contents in elementary school computer education should be transferred to the area with principles and concepts.

The fusion of learning, information, and technology presents dynamic challenges for all librarians, educators and students in 21st century libraries and schools. At the heart of this fusion is the growth of a pervasive, integrated information environment characterized by vast quantities of digital content, open choice, collaborative and participatory digital spaces, and the transition of the web environments from consumption of information to creation of information. This environment heralds important opportunities for librarians and teachers to rethink, re-imagine and recreate a dynamic approaches to information literacy instruction. Drawing on an extensive body of research undertaken through the Center for International Scholarship in School Libraries (CISSL), and published research on both information literacy and constructivist learning, this paper provides a critical examination of the current status of information literacy: its multiple conceptualizations, competing models, viewpoints, and its operationalizations in educational and library environments. The paper will challenge information literacy practices which center on simplistic, reductionist approaches to information literacy development, and the separation of information process and knowledge content. In particular it will address apparent contradictions in espoused conceptions of information literacy which revolve around "knowledge": knowledge construction, critical thinking, problem solving and the development of knowledgeable people; and information literacy practices which revolve around "information": a predominant focus on skills of access and evaluation of resources and with less attention given to engaging with found information to develop deep knowledge and understanding. The paper will present a series of challenges for moving forward with information literacy agendas in libraries and schools.

오늘날과 같이 과학기술과 정보통신 기술의 급속한 발달로 인터넷이 다르게 성장하였으며 이로 인하여 다양한 학습용 사이트가 운영되고 있다. 따라서 웹상의 교육정보가 기하급수적으로 증가되었고, 이러한 교육용 웹 자료를 컴퓨터 보조 학습 매체로 활용하고 있다. 또한 CAI(Computer Assisted Instruction), ICAI(Intelligent CAI) 나 ITS(Intelligent Tutoring System) 등을 통해 컴퓨터를 수업매체로 활용하는 방법도 많이 연구되고 있다. 하지만 현재까지 개발된 대부분의 ITS들은 CAl나 ICAI의 이론적 특징을 살릴 수 있을 만큼 진보되어있지 못한 실정이다. 특히 현행 교육과정이 지향하고 있는 수준별 교육과정에 적합하지 않고 학생들의 능력, 적성, 필요, 흥미에 대한 개인차를 고려하지 않으며, 학생 개개인의 성장 잠재력과 교육의 효율성을 극대화하지 못하고 있다. 그리고 학습자가 원하는 요구를 정확하게 파악하여 학습효과를 향상 시킬 수 있는 방법을 제공하고 있지 않다. 따라서 본 논문에서는 학습자들의 개인차 변인을 파악하여 학습자의 요구나 능력에 맞게 학습자의 학업성취를 평가할 수 있고, 수준별 교육과정에서 학습 능력이 떨어지는 학생의 학습 결손을 예방할 수 있도록 인터페이스 모듈, 학습자 모듈, 교수전략 모듈, 전문가 모듈을 가진 자기 주도적 학습을 위한 웹 기반의 MITS(Multimedia ITS: MITS)를 설계하였으며, MITS의 각 모듈들이 효율적으로 상호작용 할 수 있는 알고리즘을 제안하였다.

This study investigated the effects of the application of a variety of ICTs cause the effects on self-directed learning capability, creativity and problem-solving ability. In order to achieve the above aim, Web-Based Instructions(WBI) and instructions using CD-ROM Titles for the unit of 'the solar system and the galaxy' were applicated and analyzed which belongs to the area of 'the earth' in the subject 'science' for high school students. Instructions using WBI materials and CD-ROM titles were found to be effective on 'self-conception', 'creativity', 'future inclination', 'self-assessment ability', 'openness' and' initiative' improvement all of which belong to self-directed learning characteristics. They did not, however, show meaningful effect on improving 'learning eagemess' and 'responsibility' improvement. On looking into self-directed learning characteristics according to prerequisite learning levels, both groups and these for instruction using CD-ROM learning materials were found to have no effect on interaction. With respect to problem-solving ability improvement which is characteristic of the instruction using ICTs, WBI proved more fruitful than instruction using CD-ROM titles on improving scholastic achievement level. WBI was effective on 'fluency', 'originality' and 'resistance to premature closure'. It on the other hand, was of no use on 'abstraction of titles' and 'elaborateness' These results came from the following characteristics: WBI came into effect on 'fluency' and 'originality' in the areas of variety and vitality, which are characteristic of WBI. In the area of resistance to premature closure WBI was effective on organizing learning contents owing to the animation of picture materials which are variously presented in the web site. As a result of WBI questionnaire about WBI, an excellent effect on the structure of display, quantity of information, indication and instruction, supplementary study and further study were discussed.
