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.

앞으로 전산 시스템에서는 독자적인 사용자의 전산 시스템 이용보다는 조직내의 다수의 작업 참여자간의 의사소통과 정보의 교환 및 공유가 원활히 이루어지도록 할 수 있는 시스템의 지원이 필요하게 되었다. 이러한 전산환경을 CSCW(Computer Supported Cooperative Work)환경이라고 하며 많은 구성원이 공통된 자원을 공유함으로 해서 발생할 수 있는 보안 문제가 발생하게 된다. 이 문제를 해결하기 위한 방안으로 최근 다수의 사용자가 공유자원을 사용하는데 있어 발생할 수 있는 관리의 복잡성을 해결하기 위해 RBAC(Role Based Access Control) 개념이 연구되고 있다. 그러나 CSCW환경과 같이 Work개념이 중요한 환경에서는 기존의 RBAC개념만으로는 공유자원의 접근제어문제 해결에 어려움이 있어 본 논문에서는 Work개념을 RBAC모델에 도입한 CSCW환경 하에서의 RBAC 모델을 제시해 보고자 한다.

There are various kinds of instructional models in the 7th national curriculum. Among them, cooperative learning is given to students in some schools. In cooperative learning, the items for assessing the team members are required in order to evaluate the individual activities for problem solving, and to know the way of objective thinking each student does. Web-based environment is good for cooperative learning. In this paper, as a previous research work of web-based cooperative learning, we propose new assessment items which are based on the outcome D belongs to the set of 11 student learning outcomes design attributed framework developed by ABET EC-2000 and the cognitive categories defined by Bloom's taxonomy. These assessment items consist of self and peer assessment. The self assessment items include the evidence of the students' thought and their own assessment. On the other hand, the peer assessment can give the students the opportunities to participate in their activities enthusiastically, to offer interactive individual feedbacks, and to develop potential through various experiences.

The purpose of this study is to develop a instructive strategy model of cooperative learning for practical class in technical high school. To achieve this purpose, this study has conducted related literature investigation and interviewed with professionals for reconstruction of practice contents. As a result, 15 steps instructional strategy model of cooperative learning was designed and this model based on traditional 4 steps model, Jigsaw and STAD model which have been verified as effect. To complete the final project, all the team members must cooperate themselves and tutor their peers with learning guides which are constructed as a modular system. This instructional strategy model which is correlated with modular instruction, peer tutoring and cooperative learning is expected to enhance students' school work of psychomotor domain as well as cognitive domain and affective domain.

In this study, we proposed the learning activities using open community systems to increase critical thinking and cooperative work. We designed and implemented the Wiki system that is an opened community and general Web-Board system that is a closed community. Then, elementary students had the critical essays activities using these systems. The results of the study are as follows. First, the critical thinking activities were happened more actively at the Wiki system than at the Web-Board system. And we found that the critical thinking dispositions were improved at the Wiki system after students performed the critical writing activities. The critical thinking activities also occurred more actively in cooperative groups than in studying individual groups. In conclusion, when the students learn with the open community like the Wiki system than closed community, it is hoped that they would participate actively and their critical thinking would be improved better.

The success of cooperative learning in small groups heavily depends on how the small groups are set up. When small groups are formed, the factors such as the objectives and characteristics of the work and the capabilities and interests of the group members should be considered to maximize the interaction among the group members. However, it is not easy for teachers to manually divide their class to small groups to satisfy such conditions. In this work, we developed and implemented a student grouping system that divides the class as appropriate as possible, when given multidimensional student data and a set of conditions for forming small groups. The grouping conditions can be heterogeneous, homogeneous, and both. The grouping system can easily be used by teachers since the system can be accessed by clicking a menu button embedded into Microsoft Excel. The system has also a wide range of application areas where object grouping by various conditions is needed.

Since 2010, in general hospital, they can install western medical post, traditional Korean medical post, and dental post. So the environment is made for the Cooperative medical system between traditional Korean medicine(TKM) and western medicine(WM) to be performed. So we found out about how doctors think about TKM and what is needed for TKM & WM cooperative system to work well. When we found out about how recognition changed about TKM during their medical school years and after they became doctors, positive answer increased from 25.6% to 30%, negative answer decreased from 41.9% to 32.0%, severely negative increased from 9.3% to 16%. They changed to positive about TKM after they became doctors. But severely negative also increased. The element they lose faith in TKM is their doubt about the scientific aspects of TKM. On the other hand, severely negative recognition was also raised. 73.8% of respondents thought the most effective treatment of TKM was for myalgia. 33.3% of them answered the chance to encounter TKM was the mass media, indicating its limitation. 60.5% of them considered major reason for negative evaluation of TKM is its non-scientific aspects and only 30.9% said TKM treatment could be recommended to patients at the hospital. Doctors in WM for recognition on TKM is mostly negative and major reason is its non-scientific aspects. As the solution to this problem, scientification of TKM is suggested through research projects. These connections must be resolved to smoothly work interdisciplinary system of TKM and WM.

A computer supported cooperative work(CSCW) system is a collaboration system, which enables cooperative works among various participants through the Internet. A collaborative virtual reality environment(CRVE) can be used in scientific research and cultural research because it can provide users with virtual experiences of three dimensional molecular models in cyberspace. However, general CVRE systems are only focused on synchronous collaborations. We propose a remote collaboration system, which provides synchronous and asynchronous cooperation in collaborative virtual reality environment. The proposed system can be applied to bioscience experiments such as molecular docking process, and crystallography simulation. The proposed system is evaluated in performance comparison with previous approaches.

Cooperative education, a new paradigm of education, is a educational method of combining classroom-based education with practical work experience. To obtain appropriate learning experience during the work period, industrial mentors who provide beneficial advice and instruct students, are needed. Industrial mentors, basically, performs various roles in helping students to make the experiential learning efficiently, and the scope of their role is broad. In this paper, we classified the role of industrial mentors, proposed appropriate operating models and described the detail of their responsibilities.
