This is a complicated story. Since I involved the management of SCTNet, I have observed lots of phenomena of teachers¡¦cyber communities. It also extends my social-network, and getting acquainted with many teachers makes me to think about the meanings of teacher cyber community. The views of school-organisation, teachers¡¦ cultures, teacher professional development, educational technology and knowledge management from the literatures construct my comprehensions of teachers¡¦cyber community. But when blog arising, I try to understand: 1. How do teachers use blogs? 2. What do teachers write about in the blogs? And what¡¦s the connection between their daily lives and teaching works? 3. Rethinking how teachers¡¦ cyber community exercises and how it influences teachers. I chose one teachers¡¦blog site as my observation. Interviewing with the site manager Mr. Yu, his story represents the difficulty of advancing teachers¡¦cyber community. Secondly, I observed one of the site users, Ms. Ann, how she used the blog in a whole year. By way of interviewing, five main points were generalized from her teaching journal: blog as the source of teaching creation; the reflection of school routine activities; the assessment shadowed by the basic competence test; writing the student¡¦s anecdote and beginning to concern the life education; from the feedbacks of other internet friends, describing the interactions between Ms. Ann and her friends in order to represent the characteristics of online support group. Finally, according to Ms. Ann¡¦s story, I reflect my participating experiences of teachers¡¦cyber community and give the suggestions of the advancement of teachers¡¦cyber community in the future.

The objective of this thesis is to develop a theoretical understanding of team-based knowledge sharing and creation in professional cyber-communities. In order to provide contextual richness in environmental, information technology, project, organizational, group, and individual contexts, we apply the grounded theory approach to discover essential factors affecting team-based knowledge sharing and creation across organizational boundaries. Moreover, the thesis summarizes five types of processes of team-based knowledge sharing and creation in professional cyber-communities, defined by the sequence of causal conditions, action/interactional strategies, and consequences, and concludes nine main propositions that can be tested empirically in the future research. The research results will support sustained development of professional cyber-communities and be a basis for further studies of team-based knowledge sharing and creation across organizational boundaries.

The present generation lives in the new information age as a result of rapid computer developments and the accessibility of the internet. Therefore, in the 21st century the world has to come to grips with the cyber space culture. Internet connections in South Korea, as in many countries in the world, make access to the world available in every house. Therefore, it is a necessity to understand the internet culture and internet is becoming part of everyday life. However, at the beginning of the 21st century, the most important attribute of the mission is missio Dei: the mission is God’s mission. God is a missionary God and mission has its origin in God. And finally, God also calls people as missionaries to share his love with the world. According to Bosch (1991:368-372), our daily life has become so fast and constantly changing that we cannot use past methods to be effective today. Therefore we need a paradigm shift in our thinking towards missions today, to become more relevant. There is a need for the church to understand this paradigm shift, and implement it into its thinking and practice of mission. Cyber mission is becoming important in the information age, and there are many advantages and disadvantages to it. These advantages are to be managed carefully. It is the church's responsibility to use cyber space to the advantage of God's Kingdom. The opening up of cyber space may prove to be a gift from God to his church today. Many Christians began to share their faith with others in cyber space through the internet and internet evangelism and cyber missions were born. Today, the internet has become one of the available means of sharing and proclaiming the Gospel. It offers us incredible power to share the Good News. The Christian has the great responsibility to the great commission to deliver the gospel to the end of the earth through the cyber Mission. The South Korean church became a strong Christian church, ranking as the second missionary sending country in the world of today. The South Korean church developed the cyber mission, as they realized the power of the internet. Most of the churches have their own web site and they have already started to use the cyber space for church ministry. / Thesis (PhD)--University of Pretoria, 2012. / Science of Religion and Missiology / unrestricted
