Web 2.0 is characterized by the following themes: • The Read/Write Web: In which the Web is seen as a two-way medium, where people are both readers and writers. The main catalyst for this is social software, allowing communication and collaboration between two or more people. The Web as Platform: In which the Web is seen as a programming platform upon which developers create software applications (*like Writely—have you seen it yet?). The main catalyst for this is Application Programming Interfaces, or APIs, allowing communication between two or more software applications. • • Constantly changing and evolving—and always will From Joshua Porter’s Introduction to Web 2.0, 2006; http://www.squidoo.com/introtoweb20 Social Networking: MySpace and Facebook MySpace Professor at Texas Tech: Wesley, continued Former BCTC Student: What One Librarian is Doing • Bennington’s Crossett Library—librarian looks at students’ Favorites list for books and movies in MySpace. If the library doesn’t own the titles, she’ll order and send a message to the student telling them she’s ordered the title(s) for the library See: meredith.wolfwater.com Facebook • One librarian found that Facebook gets ―about the same usage by our students as our university portal‖ (maisonbisson.com/blog/post/11115) • Educause states that 80-90% of US college students have a Facebook profile (http://www.educause.edu/ir/library/pdf/ELI7025.pdf) • Must be Friends before you can view any profile (much stricter privacy policy) • Applications aren’t necessarily, or even primarily, written by Facebook Steve’s Profile Steve, continued Applications Not quite MySpace or Facebook, but…: Medieval Space (Richard III) (originally, it looked like this) [from: http://burchi501.files.wordpress.com/2007/02/4kjikc.jpeg] MySpace and Facebook for You • Not just a static page • Use these as ways to reach out to students: this is where your students are • Make your pages useable—if you want students to use this as a means of contact, make sure it’s easy and accessible to do so. If you want them to check blog postings, make sure they can. Why? • ―By opening itself to virtually anyone, Facebook has become a model for how communities—of learners, of workers, of any group with a common interest—can come together, define standards for interaction, and collaboratively create an environment that suits the needs of the members.‖ • For many, a central part of the college years is ―learning to be‖—experimenting with different personas, engaging with a variety of groups, and developing a set of core values. By allowing users a range of tools to negotiate and inhabit online networks, Facebook and sites like it can be an important part of this developmental process.‖ (http://www.educause.edu/ir/library/pdf/ELI7025.pdf) Join our Facebook group! http://kctcs.facebook.com/group.php?gid=6858064615 Del.icio.us A social bookmarking service Wikipedia defines Social Bookmarking as: ―… a web based service, where shared lists of user-created internet bookmarks are displayed.‖ Some Background • How long has it been around? Founded by Joshua Schachter in late 2003, bought by Yahoo in Dec. 2005 for $15-30 million • How many (and who) uses it? Traffic reached 100,000 posts per week in April 2006 (Rethlefsen, 2006) How does it Work? • Non- Hierarchical keyword categorization • No controlled vocabulary • Users ―tag‖ their bookmarks with keywords they choose themselves • All tags are PUBLIC, viewable and searchable by default – No expectation of privacy (but you can set to private) Some Common Uses for Del.icio.us • Storing bookmarks online so they can be accessed from any internet connect computer • Consolidating bookmark collections to eliminate the confusion of attempting to locate bookmarks stored on multiple computers • Personal interests – shopping, vacations, hobbies, etc. • Academic Pursuits – keeping track of online source materials in one protected location • Sharing – Bookmarks are public • Expertise Mining – all bookmarks on del.icio.us have been chosen by a human being. Exploring the results of their previous searches is a great labor saver Some Advantages • • • • • Easy to learn and use Web based Searchable Facilitates the development of communities of interest and expertise – can see who else is interested in your ―topic‖ and the sites they have bookmarked. Semantically classified tags – tags are chosen by human beings who understand the content and rank the bookmarks by their perceived utility as opposed to search engine algorithms used by internet search engines Excellent way to locate ―communities of expertise‖ ―Bundling‖ – The ability to group related tags under a category heading chosen by the user Metcalfe’s Law (or Network Effect) - The value of a service increases proportionally with the number of users. • • • Disadvantages • No controlled vocabulary! -- Lack of precision • Most social bookmark applications are relatively new • Changes quickly – new features are added all the time, so it can be challenging to keep up to date How does Del.icio.us Fit in the Classroom? • Useful for creating web-based bibliographies • Create your own taxonomies • Trend spotting • Exploratory research • Sharing tags with students to facilitate active learning Web Sites of Interest • Del.icio.us website: http://del.icio.us/ • ―The Several Habits of Wildly Successful del.icio.us Users‖. http://slackermanager.com/2005/12/the_several_hab.ht ml • Us.ef.ul A beginner's guide to The Next Big Thing http://www.beelerspace.com/index.php?p=890 • Interview with Joshua Schachter : http://www.podtech.net/technology/1030 • The Del.icio.us blog: http://blog.del.icio.us/ • del.icio.us A-to-Z by Functions : All 150+ hacks: http://www.econsultant.com/delicious-byfunction/index.html References • Etches-Johnson, Amanda.

(and annotate it?) • Or share your power point slides (and links to your blog) Second Life • What is Second Life? • The Electric Sheep Company OnRez Viewer promises a simplified interface. Implications for education? Learning styles • • • Auditory learning occurs through hearing the spoken word. Kinesthetic learning occurs through doing, touching and interacting. Visual learning occurs through images, demonstrations and body language. In such models, the term multi-modal describes people who have more than one strong learning style. Second Life may not work for every student, but neither does CMS or lecture. It will not replace these other modes of instruction; rather Second Life will compliment them. Cons • steep learning curve for non-gamers • sexually oriented regions • technical difficulties – software crashes, requires high bandwidth and powerful computers • Where can you learn more? RSS = Really Simple Syndication - RSS 2.0 RDF (Resource Description Framework) Site Summary - RSS 1.0 and RSS 0.90 Rich Site Summary - RSS 0.91 We are really just talking about FEEDS How does RSS work? Syndication is where a section of a website is made available for other sites to utilize. XML (Extensible Markup Language) is a general-purpose markup language which allows the user to define their own tags to facilitate the sharing of structured data across the web. Aggregators are client software which gather and organize syndicated web content. RSS Web 2.0 is evolving rapidly. RSS is an essential tool for keeping up with the changes! Web 3.0 What does it mean? Thanks— This important discussion obviously needs to continue…why not in our Facebook group? http://kctcs.facebook.com/group.php?gid=6858064 615
