The degree to which people share knowledge has major impacts on the effectiveness of virtual community of practice (VCoP). As an extension to the previous study which investigated the effect of individual cooperative types (cooperator, reciprocator, and free rider) on knowledge sharing, it is investigated how much increase in the degree of cooperation will enhance knowledge sharing when there are more knowledge contributors and strong ties exist across the community. Simulation method is adopted to measure the effect of the cooperative type and tie strength on knowledge sharing. The results reveal that the tie strength positively affects knowledge contribution in VCoP and strongly tied VCoP generates equivalent level of knowledge contribution as that of weakly-tied VCoP with 5% more contributors.

The purpose of this study was to develop cooperative learning model by utilizing mind practice to build mutual understandings and reliability among team members at the early stage of cooperative learning model That is to say, mind practice was applied to make the team members understanding one another and building the member's mutual confidences. The study was performed by dividing into two stages. First, the draft of mind practice based on cooperative learning model was proposed by performing a literature survey and a case study. Second, the draft model was applied to actual classrooms. And the draft was modified and developed to the final model on the basis of the draft model's strength and improvement founded during the procedure of the actual application. This draft model was implemented to 46 students who were the sophomore of department of education and enrolled the profession class of "Education methodology and Education engineering" at J college in J city for 5 weeks. From the implementation result of the model, it was obtained that there was the positive reaction on applying mind practice to the beginning stage of cooperative learning. Adding of "Re-building team" step in the original steps was suggested. The final model was modified and issued based on the research result. In summary, it was concluded that cooperative learning model based on mind practice could not only provide the harmonious interactions among team members at the step of "building the team members" but also have a positive effect on refreshing learning atmosphere of the team.

Objectives : The purpose of this study was to examine the educational effect of cooperative learning, which enables learners to make portfolio by taking advantage of their knowledge and skills acquired through practice, on an oral prophylaxis practice course in an attempt to stir up the spontaneous learning of learners, their learning interest and problem-solving skills. Methods : The selected dental hygiene students engaged in cooperative learning in oral prophylaxis practice III class in the second semester of their sophomore year by utilizing portfolio that was prepared by altering an inclusive dental hygiene practice model. They completed all the 15-week practice course, and then their portfolio was evaluated. They were divided into eight nonequivalent groups whose members were all different in academic standing, and their learning strategies and academic self-efficacy were checked before and after the instruction was provided. And their satisfaction with the class was investigated after the instruction was provided. Results : 1. There were significant gaps to $0.36{\pm}0.07$ in the charge of learning strategies after they engaged in cooperative learning(p<0.01). There were the broadest differences in cognitive strategies to 3.61, followed by metacognitive strategies to 3.19, and significant differences were found in all the subfactors(p<0.01). 2. There were significant gaps in the charge of self-efficancy to $0.13{\pm}0.06$ after they engaged in cooperative learning(p<0.01). There were the widest differences in self-regulating efficancy to 3.49, followed by confidence to 3.03 and task difficulty preference to 2.97, and significant differences were found in all the subfactors(p<0.01). 3. When their satisfaction level was analyzed after engaging in cooperative learning, there were significant gaps to 3.94 in the satisfaction level with all of the lectures(p<0.01). There were significant gaps in the satisfaction level with lecture to 4.20, with ensuring academic achievement to 4.13 and with cooperative learning to 3.48 (p<0.01). Conclusions : The above-mentioned findings indicated that cooperative learning had a positive impact on the learning strategies, academic self-efficacy and class satisfaction of the learners, and this study is expected to lay the foundation for the development of new teaching methods for dental hygiene.

This thesis has a research focus in effectively Practicing cooperative instruction where teacher-librarians play a role. The cooperative Instruction means to practice cooperatively with the subject teachers and teacher-librarians, in teaching subject matters(Korean, English, Social studies. Science, History, and so forth), using the school library. This thesis presents three steps by theory-model-support for a practice method through developing a cooperative instruction model. This is based on curriculum which is an axis of school education and an instructional design theory which is a base theory for subject matters.

The purpose of this study is to evaluate the effect of PBL program for cooperative practice between western and korean medicine. Third and fourth grade medical and Korean medical school students (experimental group: 16 students, respectively) in the Pusan National University were included in the study. Teaching methods was Problem-Based Learning (PBL) which was consist of 4 western and 4 korean medical students and 2 tutors. Modules have been developed by 8 subject experts or educational experts, who have also participated in the PBL as tutor. The program has been proceeded for 4 weeks, where two face-to-face discussions and self-directed learning were done in each module. In experimental group, students' perceptions about the other medicine were surveyed before and after the program and students' and tutors' satisfaction on the program was investigated. The perception survey was also done in the control group at the beginning of the study. The students who participated in this program had more positive perceptions about the other medicine, compared with control group. There were only significant increases on the items of 'understanding of the other medicine' between before and after the program, where no statistical differences were not observed in 'perception of the other medicine or cooperative practice'. Satisfaction in the program was positive.The PBL program enabled students to understand the other medicine, but it didn't lead changes of their perception. To improve students' perception, the program need to be kept steadily.

Recently, the educational community has attempted to implement the theory of multiple intelligences. In approaching multiple intelligences, teachers have applied the same structural approach which has been so successful with cooperative learning. Cooperative learning is easy to learn and implement, fun for teachers and students, and produce profoundly positive outcomes along a remarkable number of dimensions. Different structures are designed for different outcomes, including enhanced mastery of subject matter, improved thinking skills, team building, class building, development of social character and social skills, communication skills, classroom management, classroom discipline, and development of and engagement of each of the multiple intelligences. Cooperative learning is becoming an increasingly popular teaching strategy. In this study, it is aimed to clarify the application of cooperative learning in health education. Cooperative Learning in health education enhances student learning by: 1) providing a shared cognitive set of information between students, 2) motivating students to learn the material, 3) ensuring that students construct their own health knowledge, 4) providing formative feedback, 5) developing social and health group skills necessary for success outside the classroom, and 6) promoting positive interaction between members of different cultural and socio-economic groups. Cooperative Learning structures and techniques in health education are following. Flash Card, Focused Listing, Structured Problem-solving, Paired Annotations, Structured Learning Team Group Roles, Send-A-Problem, Value Line, Uncommon Commonalities, Team Expectations, Double Entry Journal, Guided Reciprocal Peer Questioning, What if. Because the purpose of health education is the practice, therefore health specialists have to guide powerful and effective teaching method The application of cooperative learning in health education may improve its effectiveness.

A cooperative model is presented to enable sharing of the spectrum with secondary users. Compared with the optimal model and competitive model, the cooperative model could reach the maximum total profit for secondary users with better fairness. The cooperative model is built based on the Nash equilibrium. Then a conceding factor is introduced so that the total spectrum required from secondary users will decrease. It also results in a decrease in cost which the primary user charges to the secondary users. The optimum solution, which is the maximum total profit for the secondary users, is called the collusion state. It is possible that secondary users may leave the collusion state to pursue the maximum of individual profit. The stability of the algorithm is discussed by introducing a vindictive factor to inhabit the motive of deviation. In practice, the number of secondary users may change. Adaptive methods have been used to deal with the changing number of secondary users. Both the total profit and fairness are considered in the spectrum allocating. The shared spectrum is 11.3893 with a total profit of 65.2378 in the competitive model. In the cooperative model, the shared spectrum is 8.5856 with the total profit of 73.4963. The numerical results reveal the effectiveness of the cooperative model.

Purpose: The purpose of this study was to identify the effects of applying jigsaw cooperative learning to basic nursing practicums on self-directed learning ability, self-efficacy, and learning outcomes. Methods: This study was based on a non-equivalent control group design, and the subjects were nursing students. The study allocated 30 people in the experimental group and 30 people in the control group, and jigsaw cooperative learning was applied to the experimental group for 2 hours every week for a total of 8 weeks. The traditional educational method was applied to the control group. The collected data were analyzed using SPSS v26.0. Results: The experimental group to which jigsaw cooperative learning was applied showed statistically significant differences in self-directed learning ability (F=4.49, p=.038), self-efficacy (F=6.15, p=.016), and learning outcomes (F=19.48, p<.001) compared to the control group. Conclusion: By applying jigsaw cooperative learning to basic nursing practicums, this study confirmed its effect not only on the effective domain such as self-directed learning ability and self-efficacy, but also on learning outcomes in the practical domain. We propose future studies apply jigsaw cooperative learning to various practice classes to achieve learning outcomes that focus on cultivating students' practical capabilities.
