There was another version of this eBook, it may even exist, it had nice introductions for each of the articles and a different introduction, but as I write it is lost, and so here is the 2012 version of my 2004 works, a slightly different grouping of papers, but the same content, the same changes. 2004 was for me the year the network theory of learning came together. It was a significant year for me as I spent a month in Australia and found it, not in the red centre at Uluru, as I had expected, but in the rock paintings at Kakadu and the 2,000 year-old cedars on the west coast of Tasmania. It was also the year educational blogging became mainstream and Open Content was capturing the imaginations of people. This collection of papers and transcripts varies from the technical to the expository to the polemic. What we have here are not the broad strokes of a network theory of learning – these would require more time to articulate – but the details, the structures and systems that comprise such a system. From the Semantic Social Network, which lays out the different types of networks at play, to learning in communities, to content networks and resource repositories, to the idea of distributed digital rights, cascades and connectivity, the framework of the theory is put into place, bit by bit. Moncton, May 18, 2012 An Introduction to RSS for Educational Designers Introduction RSS stands for ?Rich Site Summary? and is a type of XML document used to share news headlines and other types of web content. Originally designed by Netscape to create content ?channels? for its My Netscape pages, RSS has been adopted by news syndication services, weblogs, and other online information services. Because it is one of the simplest uses of XML, RSS has become widely distributed. Content developers use RSS to create an XML description of their web site. The RSS file can include a logo, a site link, an input box, and multiple news items. Each news item consists of a URL, a title, and a summary. Content developers make their RSS files available by placing them on their web server. In this way, RSS ?aggregators? are able to read the RSS files and therefore to collect data about the website. These aggregators place the site information into a larger database and use this database to allow for structured searches of a large number of content providers. Because the data is in XML, and not a display language like HTML, RSS information can be flowed into a large number of devices. In addition to being used to create news summary web pages, RSS can be fed into stand-alone news browsers or headline viewers, PDAs, cell phones, email ticklers and even voice updates. The strength of RSS is its simplicity. It is exceptionally easy to syndicate website content using RSS. It is also very easy to use RSS headline feeds, either by viewing a news summary web page or by downloading one of many free headline viewers. Though most RSS feeds list web based resources, several feeds link to audio files, video files and other multimedia. Why RSS is Important for Educational Designers RSS is the first working example of an XML data network. As such, and in this world of learning objects and metadata files, RSS is the first working example of what such a network will look like for educational designers. Just as news resources are indexed and distributed in the RSS network, so also educational resources can be indexed and distributed in a similar learning object network. The model provided by RSS is very different from the model provided today by learning content management systems (LCMSs). In the world of the LCMS, everything is contained in one very large software application. Insofar as content is distributed at all, it is distributed in bundled content libraries. This means that educational institutions must make a major investment in software and expertise in order to access learning content. RSS, by contrast, is not centralized. It is distributed. Content is not distributed in bundles, it is distributed one item at a time. There is no central store, repository or library of RSS content; it is all over the internet. To access and use RSS content in a viewer or in a web page, you do not need a large software application. A simple RSS reader will do the trick. For this reason, the distribution of educational content over the internet will look a lot more like an RSS network than it will an enterprise content management system. Many more people will use a distributed learning object network not only because it’s easier and cheaper, but because they can access much more content for much less money. As a result, the concept of syndicated educational content can really come into play. While there will always be a need for reusable learning objects (RLOs), anything that can have an educational application ? including

  • CHAPTER 12 Making Your Web Site Mashable
    CHAPTER 12 Making Your Web Site Mashable This chapter is a guide to content producers who want to make their web sites friendly to mashups. That is, this chapter answers the question, how would you as a content producer make your digital content most effectively remixable and mashable to users and developers? Most of this book is addressed to creators of mashups who are therefore consumers of data and services. Why then should I shift in this chapter to addressing producers of data and services? Well, you have already seen aspects of APIs and web content that make it either easier or harder to remix, and you’ve seen what makes APIs easy and enjoyable to use. Showing content and data producers what would make life easier for consumers of their content provides useful guidance to service providers who might not be fully aware of what it’s like for consumers. The main audience for the book—as consumers (as opposed to producers) of services—should still find this chapter a helpful distillation of best practices for creating mashups. In some ways, this chapter is a review of Chapters 1–11 and a preview of Chapters 13–19. Chapters 1–11 prepared you for how to create mashups in general. I presented a lot of the technologies and showed how to build a reasonably sophisticated mashup with PHP and JavaScript as well as using mashup tools. Some of the discussion in this chapter will be amplified by in-depth discussions in Chapters 13–19. For example, I’ll refer to topics such as geoRSS, iCalendar, and microformats that I discuss in greater detail in those later chapters.

With greater connectivity and interactivity enabled via web technologies, SNSs provide communication platforms for individuals to bridge geographical and temporal differences when making friends, sharing experiences, socializing with others and much more. This thesis therefore endeavors to shed light on this problem by decomposing members’ motives for participating within SNSs into identity-based, bond-based and comparison- based attachments. Each of these forms of attachment in turn affects members’ cooperative and competitive mentality towards participation within SNSs. In addition, it is further posited in this thesis that members’ identity-based, bond-based and comparison- based attachment within SNSs can be induced through the presence of deindividuation, personalization and tournament technologies respectively.

Taking a network perspective, this exploratory research examines community-level social capital outcomes of a government-led intervention.

  • YOUTH PROGRAMS AS BUILDERS of SOCIAL CAPITAL Community Development to Help Us Better Understand How the Two Are Interconnected
    Through the lens of social capital, service-learning takes on greater meaning for rural youth, adults, and communities. 5 A community development approach to service-learning: Building social capital between rural youth and adults Steven A. Henness, Anna L. Ball, MaryJo Moncheski social capital brings something new to youth and community development perspectives that has not yet been fully explained by other approaches. By shifting the focus from the individual to the community, social capital allows us to better understand the broad public value of education and youth programs. Because social capi- tal is not age specifi c, it provides insights into cross-generational networks and connections that support building more inclusive communities. Social capital can help explain why some youth are more likely to get by or get ahead, why some adults are more effec- tive within leadership roles or professions, and why some commu- nities are better able to address poverty, bounce back from natural disasters, or seize new economic opportunities. In these ways, social capital can be a bridge between youth development and The opinions, fi ndings, conclusions, or recommendations expressed in this article are those of the authors and do not necessarily refl ect the view of the U.S. Department of Agriculture.
