학교 교육과정에서 도서관 교육은 학습 내용과 학습 방법 측면에서 방법적 지식과 사고 능력으로서의 성격을 갖는다. 즉 새로운 지식의 생산에 필요한 범교과적 학습 능력으로서의 위상을 갖는다. 문제는 이러한 성격이 교과 교육 과정은 물론 학생 일상생활과의 부단한 연계를 통해서 구현된다는 점이다. 즉 학교도서관 교육의 성공을 위해서는 학교 공동체 내에 학교 도서관 중심의 교육 공동체 구성이 필요하다. 학교도서관 정보화와 순회 사서를 포함한 비정규직 자원 봉사자 확산, 다양한 형태의 업무 대행 서비스 그리고 담당교사의 도서관 운영 연수 확대 속에서 자료 조직과 운영의 일부분은 영역 보편성을 띤지 오래되었다. 따라서 학교도서관 중심의 교육 공동체 구성은 도서관 활용수업으로 대표되는 교과의 자원기반학습과의 연계성에 기반을 두고 발전하는 추세이다. 본고에서는 필자가 개발 책임자로 참여하여 2010년 교육과학기술부와 대구광역시교육청이 공동으로 일선 학교에 보급한 사서교사와 교과교사의 협동수업용 장학 자료집의 주요 내용과 활성화 방안을 살펴보고자 한다.

There is much selective confliction in nature where selfish and rational individuals exists. Iterated Prisoner's Dilemma (IPD) game deals with this problem, and has been used to study on the evolution of cooperation in social, economic and biological systems. So far, there has been much work about the relationship of the number of players and cooperation, strategy learning as a machine learning and the effect of payoff functions to cooperation. In this paper, We attempt to investigate the cooperative coalition size according to payoff functions, and observe the relationship of localization and the evolution of cooperation in NIPD (N-player IPD) game. Experimental results indicate that cooperative coalition size increases as the gradient of the payoff function for cooperation becomes steeper than that of defector's payoff function, or as the minimum coalition size gets smaller, Moreover, the smaller the neighborhood of interaction is, the higher the cooperative coalition emerges through the evolution of population.

This study aims to assure the positive influence of publishing English newspapers on improving English communicative ability and explores possibilities of enforcing an explicitly collaborative and independent learning atmosphere through a cooperative project-based publishing process. The project of publishing first KSA English newspapers has completed with a series of processes adopted from project-based learning and teaching strategies. The project involves the initiative process of selecting student editors based on their English abilities and commitment levels followed by planning subjects, themes and materials, distributing tasks and articles, and integrating and editing the outcome. Throughout the whole process volunteers participated independently and collaboratively with minimum supervision. The survey shows that the successfully published English Newspaper resulted in facilitating volunteers' positive self awareness and independent learning attitude as well as improving general English ability. The study discusses possibilities and advantages of publishing newspapers and magazines not for limited language education only, but for integrated project-based learning and teaching with suggestions for further related studies.

The purpose of this study is to analyze the learning activities which use asexual reproduction learning application(app) of students with special needs through the Cultural Historical Activity(CHAT). The asexual reproduction learning app was developed for students with special needs, and analyzed the learning activities of students with special needs in perspective of CHAT. The app was developed as subsidiary study material for asexual reproduction inquiry learning. Main functions of the app were composed of concept learning, problem solving, video playing, and report writing. According the CHAT analysis, findings indicated that students with special needs as the subject were able to organize division of labor demonstrated in cooperative learning with the object to actively participate in the class by using the tool of an app. This study also showed effective teaching strategy for improvement of learning achievement and task behavior level of student with special needs.

Telemarketing has become the center of marketing action of the industry in the information society. Recently, machine learning has emerged in many areas, especially, financial prediction. Financial data consists of lots of unlabeled data in most parts, and therefore, it is difficult for humans to perform their labeling. In this paper, we propose a fusion method of semi-supervised learning for automatic labeling of unlabeled data to predict telemarketing. Specifically, we integrate labeling results of label propagation and co-training with a decision tree. The data with lower reliabilities are removed, and the data are extracted that have consistent label from two labeling methods. After adding them to the training set, a decision tree is learned with all of them. To confirm the usefulness of the proposed method, we conduct the experiments with a real telemarketing dataset in a Portugal bank. Accuracy of the proposed method is 83.39%, which is 1.82% higher than that of the conventional method, and precision of the proposed method is 19.37%, which is 2.67% higher than that of the conventional method. As a result, we have shown that the proposed method has a better performance as assessed by the t-test.

The importance of small group activity has recently been emphasized in the gifted education in science because of the increased needs to foster the human resources that could explore through the communication and collaboration. In this study, we investigated the characteristics of the verbal interaction according to the learning styles of the gifted-students in science in the small group activity and examined how learning style affected the interaction within a group in order to seek an effective grouping strategy. The competition, cooperative, and dependent students with learning style in the small group 1 and the cooperative, cooperative, dependent students in the small group 2 were assigned by the 6 science high school students. The analyses of the results revealed that the small group 1 showed the asymmetric interaction of the low level, whereas the small group 2 showed the symmetric interaction of the high level. In other words, the frequencies of in-depth interaction in the small group 2 were higher than those in the small group 1, and also students in the small group 2 were equally involved in the activity rather than the small group 1. These results suggested that the grouping by the students' learning styles in the small group activity should affect significantly the participation decision in activity and the level of verbal interaction. Educational implications of theses findings were discussed.

This study was intended to explore the changes in teaching methods when freedom to choose curriculum, instruction, and evaluation methods is allowed and when 'free semesters' are free from entrance examination for high school. For this question, we analyzed free semester education plans of eight sample schools and interviewed 33 teachers and students respectively. The results were as follows. Firstly, all schools planned to use teaching methods for meaningful learning, although they are limited to those exemplified in guidelines for free semester. Secondarily, teaching methods adopted for free semester were characterized as activities enhancing student participation. Thirdly, teaching methods such as career exploration, scientific experimentation, cooperative learning, flipped learning, interdisciplinary learning were used only a couple of times in a semester. Changes in teaching methods were referred to enhance students' interest, confidence, self-regulation, creativity, problem-solving and cooperative learning.

The purpose of this study was to find out the learner's characteristics of students of Korea Science Academy by comparing general high school students and science high school students to Korea Science Academy students in terms of scientific attitude, learning styles, preferred teaching style, and learning environment, and to find out the differences of the learner's characteristics by gnender and school number, and to establish teaching strategies based on the findings. First, scientific attitude level of Korea Science Academy students was similar with science high school students and was high level comparing with general high students. Second, for learning style, the students of Korea Science Academy had many independent, collaborative and participatory types, Third, for the prefered science teaching style, the students of Korea Science Academy had high demands for diversification and thinking at higher levels girl students had open-mindedness and cooperation and voluntariness of higher level in scientific attitude, had more independent types in leraning style, and had higher preference of teacher's support, subject convergence and permissive atmosphere than boy students. there were no difference of student's characteristics and preferences by school number. Based on the findings, we proposed 4 teaching strategies.

In this study, we analyzed verbal interactions among 32 students in 7th graders' science cooperative learning at the levels of turns, interaction units, and conflict behavior units, and compared their verbal interaction patterns between the heterogeneous and homogeneous groups by students' collectivism. The relationships of verbal interactions with the achievement test scores and the increase of the achievement test scores were also investigated. In the analyses of turns, the distributions of the subcategories of the statements related to the task were found to be similar in both groups, and the frequency of 'explain' was highest. The frequencies of interaction units were higher in the homogeneous groups than the heterogeneous groups, and the frequency of 'symmetric interaction' was highest. In the heterogeneous groups, the frequencies of turns and interaction units for the students of high collectivism were higher than those of low collectivism. The frequencies of conflict behavior units were generally low, but the rates were similar in both groups. In the case of the homogeneous groups, the frequencies of 'avoiding' and 'competing' for the students of low collectivism were high, and the frequency of 'cooperating' for the students of high collectivism was high. In addition, the qualitative differences between the two groups were found in the interaction units and conflict behavior units. The achievement test scores and the increase of the achievement test scores were positively related with the sum of the frequencies of the statements related to the task.
