문제해결력 및 의사결정능력 향상이라는 교육 목표를 달성하기 위한 대표적인 방법 중 협동학습은 큰 효과를 보인다. 이러한 협동학습은 학습 환경이 변화함에 따라 오프라인 협동학습에서 웹기반 협동학습으로 발전되었고 요즘은 웹2.0 기반의 협동학습까지 등장하고 있다. 그러나 웹2.0의 '참여, 공유, 개방' 개념의 교육적 활용을 높이기 위해서는 무선네트워크 환경이 필수적이다. 따라서 본 연구는 무선네트워크 환경의 웹2.0 기반의 협동학습 전략을 구안하고 적용함으로서 교육적 요구에 맞는 타당성과 효과성을 검증하였다. 또한 본 연구에서 제안하는 학습전략에서 웹2.0을 통한 온라인 학습지원시스템(WCLS) 활용 방안을 제시하고 이를 통해 협동학습의 효과를 높이기 위한 교사의 역할 모형을 제안한다.

진화이론은 생명체들간의 투쟁과 적자생존의 원칙에 근거를 두고 있다. 그 중 협동으로의 진화는 공생이나 기생관계에 있는 생물들에서 발견되어 사화학, 생물학, 경제학 등의 분야에서 계속적인 관심의 대항이 되어 왔다. 특히 생명체들간에 존재하는 끊임없는 경쟁과 협동의 관계를 시뮬레이션하는 죄수의 딜레마 게임은 지금까지 많은 연구가 진행되어왔다. 죄수의 딜레마 게임이 시작된 근거는 협동으로의 진화에 관한 연구에서 시작되었다고 볼 수 있다. 대부분의 연구가 2명이 하는 죄수의 딜레마 반복게임인 2IPD에 집중되어 있는데 2IPD는 실제 세계에 적용시키는데 한계가 있기 때문에 보다 실세계에 가까운 형태를 모델링하는 N명 죄수의 딜레마 반복 게임(NIPD)에 관한 연구가 진행되고 있다. 이 논문에서는 진화 알고리즘을 이용하여 NIPD게임에서 게임자의 수와 협동으로의 진화와의 관계, 즉 죄수의 수가 증가함에 따라 협동의 정도는 어떻게 나타나는 가에 대해 고찰한다. 여러차례의 반복 시뮬레이션 결과 게임자의 수가 적을때는 대부분이 협동으로 진화하나 게임자의 수가 증가할수록 협동으로의 진화가 어렵다는 사실을 확인할 수 있었다.

The reason why Small enterprise cooperatives are important in the history of cooperatives is that they provide the basis for the development of cooperatives. Small enterprise cooperatives are composed of five or more members of small business owners and has received financial support from the government through the evaluation of the business plan from 2013. In 2018, however, Small enterprise cooperatives must be evaluated for five years of performance. In this study, we surveyed Small enterprise cooperatives members in 2015 to identify motivating factors that affect the sustainability and cooperation of Small enterprise cooperatives. On conclusion, intrinsic motivation has been found to be an independent variable affecting the sustainability and collaboration of Small enterprise cooperatives.

The purpose of this study is to draw the implication for building domestic housing-related co-operatives by understanding activities of housing-related co-operatives from case study and by suggesting the start-up typology for possible domestic housing-related co-operatives and requisites for building them. According to their activities housing-related co-operatives are categorized into three types which are housing supply and operation type, maintain and improve the existing housing type, and design and performance improvement type. National housing policy should be connected to housing co-operatives indirectly. That is, the policy direction ought to be not toward controlling housing co-operatives, letting them supply more houses directly, but toward supporting voluntary co-operatives, showing them the overall housing policy blueprint. Co-operatives cannot be a panacea. Too much protection or support for co-operatives could lead to a reverse discrimination against private companies, and the co-operatives might overuse this kind of prominent position. We need to focus on the possibility of the role of co-operatives as a facilitator for local economy rather than a perfect substitute for the existing economy system.

The Cooperatives Act was enacted. This enabled people to establish easily cooperatives at various fields. A cooperative is an important vehicle for rural community development. Therefore, the enactment of the Cooperatives Act can be a significant chance for rural policy. The Cooperatives Act have made three significant changes. First, cooperatives can start businesses at all the fields except for financial and insurance business. Second, requisites for people to establish cooperatives have been alleviated exceptionaly. Third, the Cooperatives Act introduced a new cooperative organization, social cooperative which aims to serve the socially excluded class. The self-help approach places rural community members at the core of a development process with two goals: to improve the quality of life within the community and to facilitate the community's capacity building. Community cooperatives contribute to accomplish those goals. One of the roles for cooperatives is to provide products and services at competitive prices. Providing a good or service at a competitive price bcomes increasingly important in some rural communities declines. Cooperative development processes have bic impacts on the ablility of community members to increase human asset and social capital. We conducted a survey targeting rural community businesses to grasp inclinations toward establishing cooperatives. The Cooperatives Act has gained low level of recognition. But so many community businesses wanted to establish cooperatives. This means there is a possibility for many community businesses to establish cooperatives without sufficient understanding. We suggested some policy issues for coping with this situation, as followings. First, the governments should provides rural community residents with opportunities to learn about cooperatives. Second, the current legal systems and regulations about business and social service should be reviewed to do away with the possible discrimination between the new cooperatives and the other forms of incoporation. Third, the cooperation of cooperatives should be encouraged and facilitated in rural communities.

We incorporated cooperative learning focusing on the 'Crustal Deformation' in five classes of second grade students, at an all-girls' middle school of Gimje city. The groups of cooperative learning were composed of four members of students each, according to the heterogeneous level. We conducted a pretest on the students' preference before incorporating the cooperative learning. After ten weeks of cooperative school work, the students took a post test with the same questions as the pretest. The result of this method greatly impacted the change on the students' scientific preference. It means that the students showed a positive change in their awareness of and participation in science classes, compared to before. However it is difficult to distinguish the differences in their scientific attitude on the recognition about scientists and habits which make them think scientifically. This resulted from the short period of ten weeks which is not sufficient to carry out the study strategy effectively. Surveys of the students on cooperative learning indicates that the middle level students prefer this method unlike the higher or lower level students. we are convinced that they can learn from the students of higher level and are able to help the lower level with the interaction through cooperative learning. According to the result of the survey, the method has some weaknesses; it arouses the high noise levels and consequent disturbance due to verbal interaction and of conflicts due to disagreements when they discuss the process. On the contrary, advantages are developing the students's interest in science class, helping them to learn, creating positive participation in class, and fostering mutual collaboration with other students through cooperative learning.

In this study, we investigated the perceptions and the educational needs of pre-service primary and secondary teachers on cooperative learning in science. The survey was administered to 102 seniors at the department of science education in three universities of education and 64 seniors at the department of chemistry education in three colleges of education. The results revealed that the pre-service primary and secondary teachers learned the theories and experienced the practices on cooperative learning through various methods in the several subjects, and especially had many difficulties in appling cooperative learning to the demonstrations and/or the actual science classes. The degree of their understanding on cooperative learning was comparatively high, and the perceptions on the advantage/disadvantage of cooperative learning in science, the willingness practicing it, and the outside aids influencing on implementing it were relatively positive. They highly perceived on the necessities of diverse educations related on cooperative learning in science in pre-service teacher education processes. The willingness implementing cooperative learning in science class was significantly correlated with the necessities of diverse educations. These were also significantly correlated with the perceptions on the advantage/disadvantage of cooperative learning in science, the educational assessments on the advantage/disadvantage of it, and the educational assessments on the outside aids influencing on implementing it, respectively. Educational implications of these findings are discussed.

The purpose of this study is to analyze the effect of group co-learning on English reading ability and motivation and the change in group co-learning perception after planning and applying a group co-study class program that can be applied in university liberal arts English class. In order to achieve this goal, the experiment team (34 students) conducted the class from September 2 to December 13, 2019 for 62 freshmen who participated in the compulsory liberal arts English class at the four-year university in North Chungcheong Province, and the control team (28 students) conducted the class as a typical lecture class based on the basis of cooperative learning. The English proficiency of the learners was approached by dividing the area of academic proficiency into English reading skills and the area of justice into English reading motivations. The pre-experimental learners' English reading skills were measured by excerpting the national level educational achievement assessment (high 2). The research results are as follows. First, it was shown that the English reading ability score of a group that applied group cooperative learning and the English reading ability score of a group that did not apply group cooperative learning were statistically significant differences. Second, there was a difference between the English reading motivation score of the group applying the convocation group cooperative learning and the English reading motivation score of the group not applied. Third, the change in the perception of groups applying the convocation group cooperative learning occurred before and after the experiment. This study found that the awareness of English reading, English reading motivation, and cooperative learning increased through cooperative learning among university students during liberal arts English classes, which has a positive effect on self-identity and so on.
