The purpose of study is to develop the web-contents for web based instruction (WBI) with the Science Fiction Movie (SF) and investigate the effects of application to the science learning. The results are as follows. 1) Science fiction movies for the earth science classes of middle school were selected, that is the Armageddon, the Apollo13 and the Total Recall. They are related to the chapters, the Earth and the Stars in the 8th grade science textbook. 2) The developed WBI materials were applied to the science classes of the 2nd grade in middle school through the Internet Line. and then the changes of attitude on science and recognition on using the science fiction movies to the class were analyzed. The results show that the science fiction movies have so much related to the contents of science learning and the developed WBI materials are effective to the science classes(p<0.05), but no meaningful (p>0.05) to the attitude on the science excluding the students' interest to science learning.

최근, 컴포넌트 기술의 발전에 따라 웹 기반 교육 시스템에서도 이를 응용하여 다양한 교육 컨텐츠의 제공 및 활용하려는 연구가 진행되고 있다. 또한, EJB는 웹 기반 컴포넌트 모델로서 웹 기반응용 시스템부분에서 많은 관심을 받고 있다 그러나, 컴포넌트 기반 웹-코스웨어는 이용 가능한 상용 컴포넌트와 인식부족으로 아직까지 실용화되지 못하고 있는 실정이며 분석에 관한 정형화도 이루어지지 않고 있다. 따라서, 본 연구에서는 EJB 컴포넌트를 이용한 웹 코스웨어를 분석 및 구현을 하였다. 컴포넌트들 사이의 메시지 흐름에 대한 정형적인 명세 분석을 위하여 페트리 넷을 이용하였으며, 각 기능에 따라 무상태 세션 빈의 형식으로 EJB 시스템을 구현하였다.

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.

Web-based distance teacher training should focus on increasing self-directed problem solving skills of trainers by problem-based instruction(PBL). Performance assessment evaluates achievement of learning goals through the practical performance learning to solve problems in the real situation. This study proposes a web-based performance assessment model for the distance teacher training. It reflects fairness and objectiveness issues of performance assessment which elementary teachers are concerned about through the survey on distance teacher training, and relieves instructors from overload of managing and scoring performance tests. The proposed model provides problem-based learning situations, interactions between individuals and groups, and web-based cooperative evaluation and the peer evaluation.

The purpose of this research is to suggest the direction of using blog in e-PBL. In this research we used blog for supporting individual self-regulated learning activity. We distributed space for individual learning and collaborative learning by using blog and community. 39 students participated during the 16 weeks, which includes 8 weeks of traditional e-PBL and 8 weeks of Blog based e-PBL. We conducted questionnaires and interviews, and analyzed learners' reflection notes. Data show learners feel comfortable with using blog in their independent learning activity. And blog activated learners' reflective activity and motivated their self-regulated learning.

There are two purposes of this study; 1) to identify the perception about Web accessibility of students with disabilities and their Web-based Instructional personnel (WBI personnel) in higher education, and 2) to find out effective WBI design strategies actually used by WBI personnel to design and develop accessible Web-Based instruction for students with disabilites. Sixteen students with disabilites and their WBI personnel at a mid-western university in US were recruited for individual interviews. The results showed that WBI personnel did not know about Web accessibility and were not well prepared to make their WBI accessible. They have to provide the equality and quality of life to students with disabilites by making their instruction accessible. They felt that they could not guarantee whether their WBI was accessible even after meeting current standards and guidelines. WBI personnel also suggested that they had to provide students with disabilites with various methods and use appropriate instructional design strategies in order to address their needs. Finally, some effective instructional design used by WBI personnel in order to make WBI accessible were listed.

웹 기반의 교육의 활성화로 이를 학습에 응용하기 위한 노력으로 GVA(Global Virtual Academy) 등과 같은 학습 보조 도구가 많이 발표하고 있는 설정이다. 대부분의 학습 보조 도구들은 각각의 특성들만 제시할 뿐 통합된 표준호가 되어 있지 않다. 최근 가상교육에서 학습기술이 상호운용성에 기반한 표준화의 일반적인 필요성을 인식하게 됨에 다라 가상교육의 국제표준을 소개하고 체계적으로 AICC(Aviation Industry CBT Committee), IMS Global Learning Consortium, ADL(Advanced Distributed Learning)을 중심으로 진행되어 오고 있다. 웹 기반의 교육을 통한 질의 응답의 학습방법을 고려한 도구가 없으므로 질의 응답 학습 도구(QALT)지원을 위한 표준화된 LTSA(Learning Technology Standard Architecture) 기반 시스템을 학습 객체에 대한 질의 응답과 개방형 단순 질의 응답 측면으로 구현한다. 그러므로 개방형 단순 질의 응답 측면을 구현하기 위해 학습 기술의 표준화로 제시되어 있는 LOM(Learning Object Metadata)을 통해 설계 자체를 체계화하고 전체적으로 명세 작업을 가능하게 하여 일관성을 유지하는 정련화된 문서로 질의 응답할 수 있도록 한다. 또한, Web 상에서의 Network delivery와 DTD(Document Type Definition)와 Stylesheet를 사용자가 쉽게 수정 가능하며 다양한 Linking Type을 제공하므로 단순 질의 응답 문서의 형식을 XML로 한다

The purpose of this study was to develop the level-defferentiated Web Based Instruction(WBI) program, to examine its effects on the science achievement self-directed learning characteristics, and the students’ perceptions on the WBI learning. For this purpose, the advanced and complementary WBI program of level-differentiated curriculum was developed to adapt to class fields and examine instruction facilitating efficiency. Designed and developed the WBI program make it possible to teach students according to the level-differentiated learning for the chapter, ‘weather and climate’ in high school science curriculum. The results of this study are as follows: First, level-differentiated WBI was effective to encourage self-concept, learning eagerness, future-oriented self-apprehension, creativity, self-assessment of the student’s self-directed teaming characteristics. There was no interaction effect of treatment and students’ learning ability at the self-directed learning characteristics. Second, the scores of science achievement of WBI group were significantly higher than those of conventional lecture group. There was interaction effect of treatment and students’ learning ability. However level-differentiated WBI has no effect on openness, initiative, responsibility of the student’s self-directed learning characteristics. There was interaction effect of treatment and students’ learning ability at the science achievement, Third, in the perception questionnaire of WBI teaming, many students showed the WBI teaming was good in terms of causing interaction between learners and web based learning materials including various images and animations. However there are several students who showed learning difficulties. For example they wonder which part is more important and what order is proper to study in hypertext environment.

최근에 웹 기반 교육 시스템으로서 다양한 온라인 학습에 대한 새로운 교수 모형이 제시되고 있다. 또한, 학습자의 요구에 맞는 코스웨어의 주문이 증가되고 있는 추세이며 그에 따라 웹 기반 교육 시스템에 효율적이고 자동화된 교육 에이전트의 필요성이 인식되고 있다. 그러나 현재 연구되고 있는 많은 교육 시스템들은 학습자 성향에 맞는 코스를 적절히 서비스해 주지 못할 뿐 아니라 지속적인 피드백과 학습자가 코스를 학습함에 있어서 취약한 부분을 재학습 할 수 있도록 도와주는 서비스를 원활히 제공하지 못하고 있다. 본 논문에서는 취약성 분석 알고리즘을 이용한 학습자 중심의 코스 스케쥴링 멀티 에이전트 시스템을 제안한다. 제안한 시스템은 먼저 학습자의 학습을 지속적으로 모니터링하고 평가하여 개인 학습자의 학습 성취도를 계산하며, 이 성취도를 에이전트의 스케쥴에 적용하여 학습자에게 적합한 코스를 제공하고, 학습자는 이러한 코스에 따라 능력에 맞는 반복된 학습을 통하여 적극적인 완전학습을 수행하게 된다.

인터넷 환경 아래에서 멀티미디어 매체 및 컴퓨터 통신 기술의 발전은 사회전반의 변혁을 가속화하게 되었다. 교육에 있어서도 수동적인 자료 중심으로 상호작용하고 시간과 공간을 초월하는 새로운 구조에 대한 연구가 활발히 진행되어 왔다. 새로운 교수-학습 활동의 형태로 웹을 기반으로 한 교육(WBI : Web-Based Instruction)이라는 모형이 제시되고 있다. 또한, 학습자의 필요에 응하는 코스웨어의 제공이 요구되고 있으며 이에 따라 웹 기반 교육 시스템에 효율적이고 자동화된 교육 에이전트의 필요성이 인식되고 있다. 그러나 현재 연구되고 있는 많은 교육 시스템들은 학습자가 원하는 코스를 적절히 제공하지 못하고, 계속적인 피드백과 부족한 부분을 적절히 반복 학습할 수 있도록 인도하지 못하고 있다. 본 논문에서는 학습자의 성취도 생성 알고리즘을 이용한 코스 스케줄링 멀티 에이전트 시스템을 설계하고 구현함으로써 보다 효율적인 학습을 유도한다. 제안한 시스템은 학습자의 학습활동을 지속적으로 모니터링하고 평가하여 개인 학습자의 학습 성취도를 계산하며, 이 성취도를 에이전트의 스케줄에 적용하여 학습자에게 적합한 코스를 제공하고, 학습자는 이러한 코스에 따라 능력에 맞는 반복된 학습을 통하여 적극적인 완전학습을 수행하게 된다.
