  • This study analyzed the effects of dynamic assessment in terms of scaffolding group types and young children's measurement ability levels. Participants were five-year-old children in Busan divided into 2 experimental groups and control groups. The Assessment Tools for Young Children's Measurement Ability (Ko & Hwang, 2008) consisted of 4 sub tests for ‘length', 'width', and 'weight' concepts. Data were analyzed by t-test and ANOVA. Results showed significant differences between experimental and control groups in post-test scores, but no significant differences between individual and peer collaboration groups in amount of scaffolding. Significant improvements showed in all of the measurement ability level groups : individual higher, individual lower, peer collaboration higher and peer collaboration lower level scaffolding groups.

  • This study investigates the potential components for academic research collaboration, and the factors that make it possible to achieve higher academic productivity. The components include collaboration factors and a collaboration model. We use two major collaboration factors to develop a framework for understanding the mechanisms that influence academic research collaborations: motivational factors and mediating factors. Motivational factors include self-motivation and trust whereas mediating factors are collaboration orientation and peer support. We analyze the effect for use of e-collaboration with research performance, reward, and satisfaction with e-research output. A survey of academicians was conducted, and by using the factor analysis and the structural equation model with SPSS 20 AMOS, we illustrate the possible influence of these factors on research performance and satisfaction. We discovered that both motivational and mediating factors play important roles on the success of academic research. This study offers several implications for academicians. We develop a parsimonious research model, which is related to e-collaboration in academic research. This unique model offers academicians to achieve good publication output from the research team. The motivational factor, self-motivation and trust, are important factors which has received positive impact of mediating factor collaboration orientation and peer support. Our research sheds light on the crucial factors for use of e-collaboration which offer the ultimate effect on performance and satisfaction with e-research output. Satisfaction motivates people to work more and more on the field of their interest, thereby influencing the performance of academicians. Rewards should be distributed according to performance of the individual, which will motivate the person to become more enthusiastic for his work of interest. Our evidence suggests that in understating the collaborative process, one must account for the context in which the collaboration occurs, the motivation of the collaborators, the scope and nature of the project, the roles and activities undertaken, and interpersonal processes such as trust. Researchers' motivations for engaging in collaboration were both instrumental and intrinsic.

  • For evaluating participation in collaboration project, the peer assement method is mostly used and various scoring methods have been proposed. But, the reliability and validity of the peer assessment method are still doubted for all most method. In order to overcome these weaknesss, some guidelines and training methods have been recommended. In this article, however, statistical technique is proposed for measuring individual contributions to collaboration projects considering each assessor's reliability. The gist of our proposed algorithm is that an assessor's reliability depends on the evaluation policy, and this reliability is evaluated by an analysis of variance of the scores assigned by the assessor. We also show that the proposed method is very efficient by case study in university class.

  • In recent years, peer-to-peer network have a greate deal of attention for distributed computing or collaborative application, and work of ID-based public key systems have been focusing on the area of cryptography. In this paper, we propose ID-based group key management protocols for secure communication in autonomous peer group. Each member obtains his public/private key pair derived from his identification string from Private Key Generator. No central server participates in group key management protocol instead, all group members share the burden of group key management by the collaboration of themselves, so that our scheme avoids the single point of failure problem. In addition, our scheme considers the nature of dynamic peer group such as frequent joining and leaving of a member.

  • This study intended to identify different level of teacher-efficacy, perception of principals' leadership and peer collaboration as it pertains to a teachers' job stress and job satisfaction in Elementary school. Samples include 1,031 teachers in elementary school from Korean Children & Youth Panel Survey(KCYPS) and data were analyzed using Latent Class Analysis(LCA) to identify different patterns of teacher-efficacy and perception of principals' leadership and peer collaboration. Multivariate analysis of variance were employed to identify the influence of predictors for classification of teachers' job stress and job satisfaction among latent classes. The study found three latent classes at risk class, middle-level adaptive class, and adaptive class and results showed that each distinctive class can be identified by some of predictors. Teachers at adaptive class showed higher teacher-efficacy and positive perception of principals' leadership and peer collaboration than teachers at risk and middle-level adaptive class. Also, teachers at adaptive class showed lower job stress and higher job satisfaction than teachers at two other classes. The study suggests that help teachers based on personal profile are effective rather teacher-efficacy and perception of principals' leadership and peer collaboration.

  • This paper presents a real-time collaborative system for distributed design. The aim of the system is to provide designers with a virtual workspace where they can collaborate and exchange their design knowledge in distributed environment. The system consists of two subsequent modules. One is for the visualization of design data including CAD data, documents, images, and the other is real-time collaboration module. They make it possible for distributed designers to review the design data collaboratively and to share their design knowledge. The system was implemented by using the Internet protocols such as TCP/IP and IP multicast on the peer-to-peer based network. An example is presented and discussed to validate the proposed system.

  • Objectives: This paper aims to give a review on the concept, the type, and the purpose of intersectoral collaboration, to provide a framework of intersectoral collaboration, and to review the effectiveness of intersectoral collaboration. Methods: Peer-reviewed journals were searched in Pubmed using the terms of 'intersectoral collaboration,' 'multi-sector policy,' 'intersectoral partnership,' and 'cross-sector collaboration.' In total, 240 papers were identified. After reviewing the abstracts of these papers, 59 papers were chosen to be reviewed in full-text. Contents were extracted from these papers that were pertinent to the research questions. Results: Intersectoral collaboration has been advocated since Alma Ata Declaration. However, it has been largely ignored in practice. Various factors including context, support, task, team, interactional process, individual, and overarching factors can affect the success and the failure of intersectoral collaboration. Conclusions: Some strategies to facilitate intersectoral collaboration activities and future research agenda were suggested.

  • This study investigates the influence of school cultures, specifically culture of teachers' collaboration, principals' leadership, students' peer relation, on school satisfaction of school members such as students, parents, teachers, and principals. To achieve the goal, this study analyzed the data from the survey for the Seoul education longitudinal analysis during 2010 and 2011, and conducted the following statistical meth5ods: descriptive statistics, correlation, and multiple regression. There were significant effects of students' peer relations and culture of teachers' collaboration on students' and parents' school satisfaction. This study found two implications. Culture of teachers' collaboration is the common factor to effect students' parents', and teachers' school satisfaction. Overall, this study attempted to review school satisfaction and school culture at the same time from students', parents', teachers', and principals' perspectives, even though previous literature on school satisfaction has generally focused on each groups' perspective separately.

  • The influence of peer collaboration on children's analogical abilities was studied with 120 9-year-old participants. After the pre-test, which determined the analogical level of the children, each child was assigned to 1 of 4 different learning conditions: cued/non-cued peer collaborative learning, or cued/non-cued individual learning conditions. The post-test showed changes in their analogical abilities. That is, results showed that cued peer collaborative learned improved the analogical abilities of the children, but the pattern of improvement was different by prior level of analogical abilities. We explained improvement in analogical ability by the context effect of peer collaborative learning and by the interactive effect of context with basic cognitive abilities of the children. We suggested implications of the present results for educational practice.

  • This paper discusses the relationship between debt literacy, peer-to-peer lending, and over-indebtedness in Indonesia. It is essential because the number of loans on this platform continues to increase, both legal and illegal. Data was collected online in collaboration with commercial market research firms, JajakPendapat.net. Debt literacy and over-indebtedness were measured by self-assessment with questions from Lusardi and Tufano (2009a). Questions for debt literacy are about interest compounding, debt interest, and the application of time value of money in payment options. The question for over-indebtedness is about the amount of debt and the conditions resulting from that debt. By using descriptive methods, it is clear that the majority of respondents, both borrowers and non-peer-to-peer lending borrowers are debt illiterate, and those who have poor debt literacy have huge debt. Overall, only 1.85% of the respondents were debt literate. Those who live on the island of Java have better literacy because they are the center of economic growth in Indonesia. Debt from peer-to-peer (P2P) lending also has the potential to create problems, namely over-indebtedness. P2P lending borrowers also have very poor debt literacy. However, there is no difference in debt literacy between P2P lending borrowers and non-P2P lending borrowers.
