Searching for the goldilocks zone: Trade-offs in managing online volunteer groups Online volunteer group
Productivity
Trade-off
Wikipedia
Withdrawal
English 2012 Dedicated and productive members who actively contribute to community efforts are crucial to the success of online volunteer groups such as Wikipedia. What predicts member productivity? Do productive members stay longer? How does involvement in multiple projects affect member contribution to the community? In this paper, we analyze data from 648 WikiProjects to address these questions. Our results reveal two critical trade-offs in managing online volunteer groups. First, factors that increase member productivity, measured by the number of edits on Wikipedia articles, also increase likelihood of withdrawal from contributing, perhaps due to feelings of mission accomplished or burnout. Second, individual membership in multiple projects has mixed effects. It decreases the amount of work editors contribute to both the individual projects and Wikipedia as a whole. It increases withdrawal for each individual project yet reduces withdrawal from Wikipedia. We discuss how our findings expand existing theories to fit the online context and inform the design of new tools to improve online volunteer work. 0 0

Proceedings - 2011 International Conference of Information Technology, Computer Engineering and Management Sciences, ICM 2011 English 2011 Lesson-preparing is an important stage in the field of teaching activity. The aim of this paper was to explore the use of Eduwiki as a new effective collaborative lessonpreparing platform to support teachers' collaboration and teaching. Furthermore, to verify and explore how to integrate Eduwiki into teachers' daily lesson-preparing activities, a single-group post-test and interview were used in the experiments. The study showed that Eduwiki was effective in motivating peer-supported collaborative lesson-preparing activity, as well as for teachers' mutual development. School leaders' support was the first important motivator for implementing the experiments in Expriment1 and interested the collaboration support environment was the first important motivators for implementing the experiments in Experiment2. The external condition for teachers participating collaborative lesson-preparing was very easy for operation. It showed that those experienced teachers passed their experiences on to novices using Eduwiki, and made the novices achieved high performance by collaborative lesson-preparing. 0 0

Mentoring in Wikipedia: A clash of cultures Mentoring

Wikipedia
WikiSym 2011 Conference Proceedings - 7th Annual International Symposium on Wikis and Open Collaboration English 2011 The continuous success of Wikipedia depends upon its capability to recruit and engage new editors, especially those with new knowledge and perspectives. Yet Wikipedia over the years has become a complicated bureaucracy that may be difficult for newcomers to navigate. Mentoring is a practice that has been widely used in offline organizations to help new members adjust to their roles. In this paper, we draw insights from the offline mentoring literature to analyze mentoring practices in Wikipedia and how they influence editor behaviors. Our quantitative analysis of the Adopt-a-user program shows mixed success of the program. Communication between adopters and adoptees is correlated with the amount of article editing done by adoptees shortly after adoption. Our qualitative analysis of the communication between adopters and adoptees suggests that several key functions of mentoring are missing or not fulfilled consistently. Most adopters focus on establishing their legitimacy rather than acting proactively to guide, protect, and support the long-term growth of adoptees. We conclude with recommendations of how Wikipedia mentoring programs can evolve to take advantage of offline best practices. 0 2
The effects of diversity on group productivity and member withdrawal in online volunteer groups Diversity

Conference on Human Factors in Computing Systems - Proceedings English 2010 The "wisdom of crowds" argument emphasizes the importance of diversity in online collaborations, such as open source projects and Wikipedia. However, decades of research on diversity in offline work groups have painted an inconclusive picture. On the one hand, the broader range of insights from a diverse group can lead to improved outcomes. On the other hand, individual differences can lead to conflict and diminished performance. In this paper, we examine the effects of group diversity on the amount of work accomplished and on member withdrawal behaviors in the context of WikiProjects. We find that increased diversity in experience with Wikipedia increases group productivity and decreases member withdrawal - up to a point. Beyond that point, group productivity remains high, but members are more likely to withdraw. Strikingly, no such diminishing returns were observed for differences in member interest, which increases productivity and decreases member withdrawal in a linear fashion. Our results suggest that the low visibility of individual differences in online groups may allow them to harvest more of the benefits of diversity while bearing less of the cost. We discuss how our findings can inform further research of online collaboration. 0 0
