With progress of informationalization, education has been transformed from traditional uni-direction education to bi-directional and consumer-oriented education, which is performed by learner's self study and interactive education of multiple dimension between a learner and contents, between a learner and a teacher, and between a learner and a learner irrespective of space-time. According to this trend, a new education method has been required. Therefore, in this paper, we will propose real-time consumer-oriented distance education system of making interaction maximum using WBI. In this system, a learner can participate in an individual study case by multiple interaction with a learner's designing and plaining study, and also participate in group study case by way of discussion and conversation among participants.

This research aims to investigate e-Learning behavior and its different features which may vary depending on learners' characteristics and their prior e-Learning experiences. For this purpose, a survey was conducted for adult learners who had e-Learning experiences. It included various questions including place, time and process of e-Learning. The result showed that features of e-Learning behavior varies according to learner characteristics, such as gender, educational background, and their work experiences. It also revealed that work environment and the nature of e-Learning courses are influential factors for their learning behavior.

The Internet have increased the number of digital web documents related to the history and traditions of Korean Culture. However, users who search for creators or materials related to traditional cultures are not able to get the information they want and the results are not enough. Document classification is required to access this effective information. In the past, document classification has been difficult to manually and manually classify documents, but it has recently been difficult to spend a lot of time and money. Therefore, this paper develops an automatic text classification model of traditional cultural contents based on the data of the Korean information culture field composed of systematic classifications of traditional cultural contents. This study applied TF-IDF model, Bag-of-Words model, and TF-IDF/Bag-of-Words combined model to extract word frequencies for 'Korea Traditional Culture' data. And we developed the automatic text classification model of traditional cultural contents using Support Vector Machine classification algorithm.

Problem-Based Learning(PBL) is one of constructionism's model which is learner-centered learning. In this paper, a role-play base PBL using character is proposed to study importance of information security. It is different from the other PBL models in that it reflects the characteristics of learners, learning task. And it is learning support system which the learners preside their own learning activities using Internet and mobile devices. By experimental result showed that proposed method was more effective than traditional teacher-oriented teaching method about information security in self-directed learning, cooperative learning, contents-making and attraction.

Abstract characteristic of algorithm may disturb improving learners' motivation and learning. Therefore, a design of teaching and learning method requires to minimize the learner's intrinsic cognitive load and to maximize the learning motivation. We developed an algorithm learning program by playing to enhance learning motivation and achievement for vocational high school students. And then, we implemented the developed program in vocational high school classes and analysed the educational effects of the developed program. We found that the developed program was helpful in enhancing learners' learning motivation and achievement level. It means that doing the activities, such as playing games, helps learners to acquire an algorithm concept that has abstract nature and is difficult to understand.

최근 들어 점차 지능형 서비스 로봇들이 인간의 실생활 속으로 들어옴에 따라, 로봇 스스로 다양한 물체들을 효과적으로 조작할 수 있는 지식을 습득하는 기계 학습 기술들이 매우 주목을 받고 있다. 전통적으로 로봇 행위 학습 분야에는 강화 학습 혹은 심층 강화 학습 기술들이 주로 많이 적용되어 왔으나, 이들은 대부분 물체 조작 작업과 같이 다차원 연속 상태 공간과 행동 공간에서 최적의 행동 정책을 학습하는데 여러가지 한계점을 가지고 있다. 따라서 본 논문에서는 전문가의 데모 데이터를 활용해 보다 효율적으로 물체 조작 행위들을 학습할 수 있는 모방 학습과 강화 학습의 통합 프레임워크를 제안한다. 이 통합 프레임워크는 학습의 효율성을 향상시키기 위해, 기존의 GAIL 학습 체계를 토대로 PPO 기반 강화 학습 단계의 도입, 보상 함수의 확장, 상태 유사도 기반 데모 선택 전략의 채용 등을 새롭게 시도한 것이다. 다양한 성능 비교 실험들을 통해, 본 논문에서 제안한 통합 학습 프레임워크인 PGAIL의 우수성을 확인할 수 있었다.

Objectives: The purpose of this study is to compare educational effects between traditional classroom instruction and video self-instruction (VSI) for cardiopulmonary resuscitation (CPR) in boy's high school students. Methods: This study was carried out targeting totally 96 boy students(47 people for experimental group, 49 people for control group) in the second grade of high school where is located in G city of G province from July 9-10, 2009. The experimental group and control group were arbitrarily selected two classes in the second grade. One class was assigned to the experimental group. another class was assigned to the control group. The experimental group was educated with VSI for CPR. The control group was educated with traditional classroom instructions for CPR. The analysis was performed with SPSS WIN (version 12.0) program using frequency chi-square($x^2$) test, independent samples t-test, and paired t-test. Results: After instructions, the knowledge, attitude, self-confidence, and skill performance accuracy scores on CPR increased statistically in both group. The increases of self-confidence ($2.40{\pm}0.73$) and skill performance accuracy score ($2.67{\pm}0.29$) in the experiment group were significantly higher than those ($2.01{\pm}0.96$ and $2.54{\pm}0.31$) in the control group, respectively. Conclusion: This study suggested that VSI was more effective than traditional classroom education for self-confidence and skill-performance accuracy in CPR. To confirm it, more studies are warranted.

Although cooperative learning strategies in many subject areas have been found to be effective, the effect of cooperative learning on academic achievement in science laboratory setting is not clear. Reported results on the effects of the strategies for higher achieving students are not also consistent. In this study, the cooperative learning strategies emphasizing student-centered learning which included higher order thinking activities were used in a elementary school science course. The cooperative and traditional learning groups were selected from fifth-grade classes, and taught about dissolution and solution for 16 class periods. The effects of the cooperative learning strategies upon students' academic achievement, science process skill, the attitude toward science instruction, and the perceptions of classroom environment were investigated. Two-way ANCOVA results revealed that the test scores of academic achievement and science process skill for the cooperative learning group were significantly higher than those of the traditional learning group. No interaction between the instruction and the level of previous achievement was found. The perceptions of confliction were higher in cooperative learning group. In the attitude toward science instruction and the perceptions of participation, however, no significant difference between the two groups was found. Educational implications are discussed.

The purpose of this research is to compare the effect of unplugged learning method with traditional lecture method on intellectual disability students' informatics education achievement. For this goal, we developed a new unplugged learning method and new appropriate teach-learning materials that can improve the intellectual disability students' informatics education achievement. We randomly divided special school specialized course freshman into the experimental group and the control group. We applied unplugged learning method to the experimental group and lecture teaching method to the control group. According to these results, Intellectual disability students participated in task interestingly and spontaneously. It has been proved that the teaching-learning materials applied unplugged learning method were helpful for intellectual disability students' informatics education achievement.

현대사회는 산업사회의 발달에 따른 물질 만능주의로 인해 이기적이고 배타적인 사회풍조가 사회 전반으로 점차 확산되면서 전통적 가치관이 경시되고 공동체 의식이 퇴색되어 가고 있는 실정이다. 그러나 인터넷의 발달은 시공간을 초월하여 가정과 학교가 가상의 공간에서 정보의 공유와 상호작용을 할 수 있게 해 줌으로써 웹을 활용한 인성교육이 가능해졌다. 본 논문에서는 이러한 웹의 특성을 활용하여 학습자가 다양한 체험활동 중심의 인성교육을 마을 단위로 실천하도록 한 후 웹 상에 구축된 인성교육 시스템을 이용하여 자신이 체득했던 체험활동 정보를 서로 공유하고 학생, 교사, 학부모가 상호 작용하게 함으로써 학습자가 지속적으로 인성 교육에 관심과 흥미를 갖고 참여할 수 있도록 하는 공동체 의식 함양을 위한 인성교육 시스템을 설계하였다. 더 나아가 웹기반 인성교육 시스템을 통해 마을을 사랑하는 마음과 공동체 의식을 함양하여 마을에 대한 긍지와 자부심을 갖고 상부상조하는 전통을 가꾸어 나가는데 도움을 주고자 한다.
