Communities of practice are groups of people who share a concern, a set of problems or a passion about a topic, and who deepen their knowledge and expertise in this area by interacting on an ongoing basis (Wenger et al, 2002). An understanding of why working, technical professionals participate in knowledge- based communities of practice can provide better opportunities to support individual and organizational knowledge management strategies. Online communities of practice were investigated at two global corporations: Xerox and IBM. At Xerox, Eureka is an internal network service designed to support knowledge sharing and problem solving by a community of practice for field service technicians. It allows the submission of problems from field service technicians and the retrieval of validated solutions for use and adaptation, by all members of the global Eureka community. At IBM Corporation, public network based communities of practice were investigated that focused on db2™ and Websphere™ software technology. Unlike the Xerox Eureka community of practice, knowledge contributions at IBM communities of practice are not validated prior to submission and access is open to public participation globally by IBM employees and by independent users of IBM software technology. The purpose of this case study research was to explore and to describe how and why participants became members of communities of practice – what influenced them to join and to participate. We collected survey data from participants in these communities, to examine the relationships among members’ expectations of purpose, their relationship to the community of practice, their attitudes toward information handling, the costs and benefits of membership, the size of the community of practice and the resulting participation behaviour in these knowledge-based communities of practice at Xerox Corporation and IBM Corporation. As one aspect of exploring user behaviour, we investigated the applicability of two theoretical frameworks for understanding user behaviour in these communities, based on propositions from normative and utility theory and from public goods critical mass theory. The research study provides a test for the explanatory power of public goods, utility and normative theories in a new area; namely, online knowledge-based communities of practice in workplace contexts. This analysis provided support for the applicability of utility theory and for some aspects of public goods-based theory/critical mass theory. The findings of the case study point out some differences in the two communities of practice. A majority of the IBM-based community members reported belonging to multiple communities (6-10) and using access to the community to form online social networks and to meet members outside the community at in-person meetings. They reported their participation as being self-directed and on an ad hoc basis. Most respondents were community members for less than 2 years. In contrast, a majority of Eureka members reported belonging only to the Eureka community and do not report forming online social networks in Eureka. Participation in Eureka is seamlessly integrated into prescribed, standard work practices of the company and supported by company management and with resources. Most respondents were community members for over 5 years. The analysis of members’ contributing behaviour in two online communities of practice reaffirms that the majority of members are passive participants with a core group of regular message contributors. Message composition is a careful and deliberate activity requiring communication discipline, time and effort. Members in both settings reported a strong desire to spend more time in their communities (and more time per visit). Communities of practice are dynamic complex entities that present not only a theoretical challenge but also a practical challenge. This study’s results point to the complexity of facilitating communities of practice: benefits dynamics and flow and permanence dynamics of membership can only be externally managed to a limited extent. The participants’ roles need to be conceptualized in ways that support different types of participation while at the same time highlighting the inherently cooperative nature of self-managed communities of practice.

In the era of knowledge economy, more and more people view online communities of practice (CoPs) as wellspring of precious knowledge. Interestingly, many researchers support the notion that CoPs must develop over time; they are not designed or made but grown, however, there is no systematic theory of online community development (Matzat, 2003). Furthermore, when changes with time are specialized concerned, several questions regarding CoPs development remain unanswered. Since online CoPs are formed by groups of people, existing group development models may provide valuable lens for us to understand the driving forces behind. Nevertheless, drawn on the autotrophic and open system of online CoPs, there exist several differences between traditional groups and online CoPs, such as self-select membership, high member fluidity, impossible to know all members in a large member base, unlimited life spans, and no given tasks have to complete. Furthermore, some defects in prior group development studies are also identified. To answer the research question and avoid problems identified in prior group development studies, this study plans to conduct a longitudinal exploratory study on three online CoPs lasting at least three years by overcoming the defects of unreal subjects such as experimental student groups or arranged tasks. Besides, three years of longitudinal study may prevent from the bias drawn from single snapshot and limited life span. Furthermore, we decide to adopt the ecological perspective for several reasons: First, the evolutionary process is akin to the central theme of ecological theory. Therefore the mechanisms of change can be suitably inferred from ecological perspective. Moreover, the ecological perspective is more holistic and macroscopic, and accordingly the problem of high individual member fluidity can be easily tackled. Second, many ecological concepts are used in numerous CoPs-related literatures to describe CoPs. In addition, being immersed in some CoPs for several years, we found that members usually use some ecological terms to describe their CoPs or other members. Third, several studies indicated that the ecological approach provides a powerful framework for understanding complex human social issues. We view each CoP as an ecosystem because ecosystem is the lowest level in the ecological hierarchy that is complete with all the necessary components for function and survival over the long term. This research also adopts the multiple case study approach. Firstly, online CoPs are categorized based on group member interaction statistics. Three categories of online CoPs are identified and three online CoP belonging to these three categories, respectively, are selected as representative cases. Every six months the aggregated data of targeted online CoPs are treating as the unit of analysis. The whole 'lives' of online CoPs under study are analyzed, by the way to avoid the problems of zero-history groups and drawn bias conclusion from observation of groups over different time periods. We attempted to detect and analyze the changes of community structures in the ecosystem using social network analysis tools. Moreover, since quantitative data may fail to capture some interaction modes, this study employs content analysis and semi-structural interviews as complementary vehicles to gain insights into the detailed evolutionary process. Finally, this dissertation follows Yin's (1994) analytic strategy of descriptive framework, and thus uses the metaphor of an ecosystem to integrate and organize sets of dimensions in relation to the evolutionary process of online CoPs. Drawn on Odum¡¦s (1971, 1983, 1993) model of ecosystem, this study proposes a descriptive framework based on ecosystem ecology and network analysis. There are primarily three components: organisms, energy, and nutrients; three types of connections: interactive network, keystone structure, and roles distribution. There are also five categories of constraints on the ecosystem functioning. They serve as dimensions of describing changes within an ecosystem over time. Further, these changes are interpreted from ecological perspectives, where insights into the mechanism governing the development process are generated to postulate the development model of online CoPs.

Teachers are required to constantly change their pedagogy throughout their career, either in response to new theoretical approaches or new technological innovations. It is a profession that is characterised by dynamism and constantly strives to advance its practices to improve outcomes in student learning. However, current professional development programs are seen to be failing to meet the needs of the teachers, students and education policy. Research has shown (Huberman, 1995; Richardson, 1990), there has been little discernible change in teaching practice from current professional development programs, thus an alternative solution is needed. The premise underlying this study is that the use of online communities of practice may present a solution to the failure of current professional development programs in effecting change to teaching practice. Thus it is the intention of this thesis to investigate if online communities of practice can realise this potential. The research was conducted within the paradigm of qualitative analysis. The study was conducted as a multiple explanatory case study also known as a collective case study (Yin, 2003) and this approach reflects the current shift in trends of research in education. As Richardson (1994) stated, it has shifted &quotfrom a focus on effective behaviours toward the hermeneutic purpose of understanding how teachers make sense of teaching and learning" (p. 5). The approach used in this thesis provided insights into the value of online communities as authentic contexts for supporting professional development particularly in relation to relationships, communication and collaboration between teachers around professional inquiry, problem solving and emotional aspects of teaching. The results of the study show that online communities of practice are a valuable source of continuous professional development for teachers. They have the ability to provide support as teachers accommodate the constant changes and the need to acquire new skills and knowledge. The strength of this method of PD lies in its ability to be self-sustaining and generative. Teachers have access to authentic, relevant and flexible learning that is not constrained by time and can be accessed according to members needs.

The aim of the study was to investigate the dynamics of two online communities of practice (oCoP) for preservice teachers. The research process encompassed three main phases. Phase 1 was related to the design and development of online environment. By the help of existing literature and a pilot study, a portal which is called as &ldquo / Professional Development Circle (PDC)&rdquo / was developed. In Phase-2, 28 preservice teachers from three different universities participated to an online course as a part of an undergraduate course. During the term, they discussed on different video cases which were recorded in real classroom environments and produced new lesson plans for these lessons in the light of given suggestions. In the third phase, the same preservice teachers got involved in a different online environment without any grading motivation in the Phase 2. They discussed on some hot topics in mathematics teaching with other preservice teachers, academicians and experienced teachers. This research study was mainly a qualitative study. Two cases of the study were two oCoP which included mandatory or voluntary participation of preservice teachers to discussions. The data were collected through written reflection reports, observations and interviews. In addition, private e-mail exchange with participants and discussion list message history were rich data sources. The data were analyzed according to qualitative data analysis techniques. The design principles and findings of this research study were discussed in the frame of Activity Theory. This study revealed outcomes of two online communities of practice environments in preservice teacher education. In addition, motivators and barriers to be active in oCoP environments were discussed. Some of the motivators were getting more responsibility, self confidance, sociable personality, altruism, sincerity in the environment, and quality of materials while some of the barriers were not wanting to enter a fight, lack of time, the idea &ldquo / max benefit minimum effort&rdquo / , feeling availability of others, and Internet access and computer availability.

Information and communication technologies (ICTs) are having remarkable effects and promise potential solutions to many of the South Pacific islands’ geographic, economic and social challenges. Access to ICTs is also an increasingly important factor for education and training in the region. While the Pacific eLearning Observatory, supported by the University of the South Pacific, has been monitoring the development and access to ICT in education across the 12 university’s campuses, studies that specifically examine the attitudes and understanding of educators working on the islands of the South Pacific towards the use of ICT in their profession, as well as for their professional development, are rare. This study aims at addressing the gap in the literature by examining the professional development of facilitators working in blended learning environment across the remote islands of the Cook Islands. The research outcomes of this study are based on the analysis of in-depth, semi-structured interviews, and the theoretical foundation of this thesis is grounded in the social and situated theory of learning. By closely examining the facilitators’ perceptions, the project sheds new light on the still little recognised concept of online communities of practice in teaching and learning. The central finding of the study is that participation in online communities of practice offers on-going opportunities for learning, development and support, and reduces the feeling of remoteness and isolation associated with the geographical conditions of the South Pacific region.

abstract: A core reform area of President Obama’s Race to the Top (RTT) framework, the Statewide Longitudinal Data Systems (SLDS) program, offered funding to states for the development of their own data systems. As a result, Arizona received funding to build a longitudinal student data system. However the targeted audience—teachers—needed training to move from a state of ‘data rich but information poor’ to one of developing actionable knowledge. In this mixed methods action research study, six teachers from three schools participated in job-embedded data-informed decision making (DIDM) and root cause analysis (RCA) professional development to improve their abilities to employ DIDM and RCA strategies to determine root causes for student achievement gaps. This study was based on the theories of situated learning, specifically the concept of communities of practice (CoP), change theory, and the Concerns-Based Adoption Model (CBAM). Because teachers comprise most of the workforce in a district, it is important to encourage them to shift from working in isolation to effectively implement and sustain changes in practice. To address this concern, an online wiki provided an avenue for participants to interact, reflect, and share experiences across schools as they engaged in the application of new learning. The results from this ten-week study indicated an increase in participant readiness levels to: (a) use and manage data sources, (b) apply strategies, and (c) collaborate with others to solve problems of practice. Results also showed that participants engaged in collaborative conversation using the online wiki when they wanted to share concerns or gain further information to make decisions. The online collaboration results indicated higher levels of online discussion occurred when participants were attempting to solve a problem of practice during the learning process. Overall, participants (a) used collaborative strategies to seek, create, and/or utilize multiple sources of data, not just student learning data, (b) worked through implementation challenges when making changes in practice, and (c) sought further types of data collection to inform their decisions about root causes. Implications from this study warrant further investigation into the use of an online CoP as an avenue for increasing teacher collaboration across schools. / Dissertation/Thesis / Doctoral Dissertation Leadership and Innovation 2016

In recent years there has been growing enthusiasm among researchers for the promotion of online learning communities designed to support professional learning in preservice teacher education. The primary purpose of this qualitative study is to explore the role of such an online community in supporting student teacher learning during the school placement in a Chinese Normal University, and hence to enrich the understanding of student teachers’ learning experiences in an online ecology. The study’s subjects included a cohort of 42 student teachers enrolled on a four-year preservice teacher education programme, along with two university supervisors at one of China’s teacher-training universities. Primary data were collected from six weeks of online threaded discussions and from semi-structured group interviews. Supplementary data were taken from an end-of-school-placement evaluation and web-tracking logs. Data analysis has been informed and illuminated by the theoretical proposition of communities of practice. The findings of the study indicate that the online learning community is a valuable resource for supporting student teachers both personally and professionally. Findings suggest that online communication not only helps student teachers tackle immediate teaching concerns and technical problems, but, more importantly, provides them with opportunities to reflect collectively, to co-construct new teaching ideas, and to gain professional discourse competence through articulating and negotiating their evolving thoughts on teaching as a profession. In this regard, student teachers are found to be more comfortable with online self-disclosure of their personal and professional encounters and critiquing each other than they are with face-to-face communication. The research also shows that university supervisors experience mixed feelings about the fact that student teachers are more able to take ownership of their learning and therefore become less dependent on supervisor guidance as time wears on. Furthermore, these findings provide evidence suggestive of a possibly reciprocal relationship between Chinese view of learning and the building of online learning communities. Based on the results of the study, I provide recommendations as to how the significance of the school placement can be reinforced in fostering distributed student teachers’ professional growth. The results also contribute to a better understanding of the key factors in the design and implementation of effective online learning communities within preservice teacher education in China. Finally, the analytical approach used in this study provides fresh methodological insight into an alternative means of analysing online postings. It thus contributes both to the theorisation of learning communities in the context of computer-mediated communication, and to the further development of concepts drawn from the communities of practice literature.
