Developing a Web 2.0-Based System with User-Authored Content for Community Use and Teacher Education
Education Tech Research Dev DOI 10.1007/s11423-009-9141-x RESEARCH Developing a Web 2.0-based system with user-authored content for community use and teacher education Lauren Cifuentes • Amy Sharp • Sanser Bulu • Mike Benz • Laura M. Stough Ó Association for Educational Communications and Technology 2009 Abstract We report on an investigation into the design, development, implementation, and evaluation of an informational and instructional Website in order to generate guide- lines for instructional designers of read/write Web environments. We describe the process of design and development research, the problem addressed, the theory-based solution, and the evaluation and testing of that solution. Based on our experience, we then identify sixteen guidelines for future designers and developers of read/write Web-based learning environments. The study demonstrates how read/write Web technologies can be used to address general problems that have intrinsic societal importance; examines implementation of a read/write technology in a real-life context, thereby testing distributed cognitions learning theory; informs the design of similar environments; and provides grounded theory for the design and development of read/write Web learning environments. Keywords Design and development research Á Read/write Web Á Web 2.0 Á Distributed cognitions Á Social constructivism The emergence of read/write Web (Web 2.0) technologies such as wikis, Weblogs, Real Simple Syndication, Webcasts, and interactive photo galleries, has empowered users to actively contribute to the content of the Internet. By 2003, 44% of adult Internet users had participated in the interactive capabilities of the Internet by posting in at least one read/ write Web environment (Lenhart et al. -

This subject is considered within the frame- collaborative authoring. work of computer-supported cooperative work (CSCW). Wikis have been around since the mid1990s, though it The author identified thirty-three library wikis and is only recently that they have become ubiquitous.

Knowledge Management by Wikis
Knowledge management by wikis Sander Spek [email protected] Institute for Knowledge and Agent Technology Universiteit Maastricht Abstract Wikis provide a new way of collaboration and knowledge sharing. Wikis are software that allows users to work collectively on a web-based knowledge base. Wikis are characterised by a sense of anarchism, collaboration, connectivity, organic development and self-healing, and they rely on trust. We list several concerns about applying wikis in professional organisation. After these concerns are met, wikis can provide a progessive, new knowledge sharing and collabora- tion tool. 1 Grassroots knowledge sharing During the last decades, the sharing of information and knowledge has gone through an unheard rapidisation. Both the amount of information shared, as well as the speed in which this happens, has taken a huge flight. In many fields of progress, professional organisations were more ad- vanced then ‘amateur knowledge sharers’. Remarkably, in some fields this has changed over the years. On the Internet, many succesful grassroots initiatives have popped up, that still didn’t make it to the somewhat static and controlled environment of professional business organisa- tions. Think of free-software projects, but also of free-information projects, as wikis, weblogs, and open news sites like Indymedia. (Möller, 2005) In this paper, we will examine on of the most popular and upcoming knowledge sharing enablers on the Internet: wikis. Consequently, we will discuss why wikis are not (yet) adequate for a professional environment, and what could be changed to have companies adapt the power of wiki-based knowledge sharing too. 2 Wikis Möller (2005, page vii, translated) defines wikis as “open websites that can be edited by every visitor.”1 We will extend this definition in two ways: (1) we explicitly state that modifying can also include deleting information, and (2) we mention the fact that a wiki is in fact a knowledge base. -
A Buzz Between Rural Cooperation and the Online Swarm
A Buzz between Rural Cooperation and the Online Swarm Andrew Gryf Paterson1 Abstract This article introduces and explores connections between rural traditions and contemporary projects of voluntary cooperation within emergent online network practices. The key examples are mainly from Finland, the Baltic Sea region, and USA. Reflections are made on the emergence of such connections during a trans- disciplinary seminar organised by the author. The main body of the essay mixes social and network culture history, including rural village community support, known as “talkoot” in the Finnish language, its establishment within cooperative development during the 20th century, and the information communications and technology society of contemporary Finland. Discussions of collaborative web platforms such as wikis, the BitTorrent protocol, and “crowd-sourcing” open up questions considering their relation to older cultural traditions. The paper concludes with contemporary examples of where traditions of rural cooperation have conceptually assisted several Finnish entrepreneurial and activist projects. Throughout the paper “the swarm” is identified as a concept worth exploring further to illustrate where the expansive potential of network culture meets concentrated local action. Introduction I write reflecting upon connections which emerged from planning the Alternative Economy Cultures (Alt.Econ.Cult) programme of Pixelache Festival, during winter 2008-2009 and, in particular, the seminar event on April 3, 2009 in Helsinki. To give some contextual background to this event, Pixelache is both a cultural festival and an organized network.2 It brings together people interested in topics such as: electronic arts; participatory cultures and subcultures, including the exploration of grassroots organizing and networks; politics and economics of media/technology; media literacy and engaging environmental issues. -

OVERVIEW Socialization and collaboration technologies are currently reshaping the established enterprise collaboration market as well as creating whole new categories of offerings, especially around private social platforms. In addition, many other enterprise applications such as CRM and unified communications are heavily transformed through the incorporation of new technologies including group messaging & activity feeds, document collaboration, and analytics. Much of this change is being driven by the consumerization of IT and the incorporation of social technologies. As businesses look to leverage the benefits of improved “connecting” and “network building” that employees have experienced with Facebook and other social solutions, a convergence is occurring between the enterprise social software and collaboration markets. -

Public Wikis: Sharing Knowledge Over the Internet
Technical Communication Wiki : Chapter 2 This page last changed on Apr 15, 2009 by kjp15. Public Wikis: Sharing Knowledge over the Internet What is a public wiki? A public wiki refers to a wiki that everyone can edit, that is, it is open to the general public on the Internet with or without a free login. Anyone is welcome to add information to the wiki, but contributors are asked to stay within the subject area, policies, and standards of the particular wiki. Content that does not relate to the subject or is not of good quality can and will be deleted by other users. Also, if a contributor makes a mistake or a typo, other users will eventually correct the error. Open collaboration by anyone means that multiple articles can be written very fast simultaneously. And, while there may be some vandalism or edit wars, quality of the articles will generally improve over time after many editors have contributed. The biggest public wiki in the world, with over 75,000 contributors, is Wikipedia, "the free encyclopedia that anyone can edit" [1]. Wikipedia has over 2.8 million articles in the English version, which includes over 16 million wiki pages, and is one of the top ten most popular websites in the United States [2]. There are versions of Wikipedia in ten different languages, and articles in more than 260 languages. Wikipedia is operated by the non-profit Wikimedia Foundation [3] which pays a small group of employees and depends mainly on donations. There are also over 1,500 volunteer administrators with special powers to keep an eye on editors and make sure they conform to Wikipedia's guidelines and policies.
