Web 2.0 refers to the second generation of internet-based services that emphasize user-generated content, interoperability, and collaboration on the World Wide Web. Some key aspects of Web 2.0 include user blogs, wikis, sharing of photos, videos, and podcasts, as well as new ways of interacting via social networking, folksonomies, and APIs. While Web 1.0 focused on static, reader-only websites, Web 2.0 aims to harness the collective intelligence of users by facilitating contribution and interaction between users on the internet.

3. Web 2.0 Web 2.0, a phrase coined by Dale Dougherty in 2003 made famous in a paper called What is Web 2.0: Design Patterns and Business Models for the Next Generation of Software by Tim O’Reilly it is not a set technological standard or protocol it is a term to describe the movement/revolution about the social connection and interaction of the web and services and technologies that sponsor and promote it. the “second phase” of the internet 2006 Time Person of the Year: You

4. Web 2.0 the meaning varies Dave Winer [a software developer and entrepreneur] says: “Web 2.0 is a marketing concept used by venture capitalists and conference promoters to try to call another bubble into existence.” Om Malik [a technology writer] says: “Web 2.0 as a collection of technologies - be it VoIP, Digital Media, XML, RSS, Google Maps… whatever … that leverage the power of always on, high speed connections and treat broadband as a platform, and not just a pipe to connect.” kind of a buzz word

5. What was Web 1.0? Web 1.0 was about reading, Web 2.0 is about writing Web 1.0 was about companies, Web 2.0 is about communities Web 1.0 was about client-server, Web 2.0 is about peer to peer Web 1.0 was about HTML, Web 2.0 is about XML Web 1.0 was about home pages, Web 2.0 is about blogs Web 1.0 was about lectures, Web 2.0 is about conversation Web 1.0 was about advertising, Web 2.0 is about word of mouth Web 1.0 was about services sold over the web, Web 2.0 is about web services From Darren Barefoot, a technology writer modern vs. post-modern ways of thinking

6. Examples of Web 2.0 Blogs Wikis Tagging Multimedia Sharing RSS Podcasting Second Life

7. BLOGS blog or weblog simple webpage consisting of brief postings of opinion, information, etc. blogosphere a collective term encompassing all blogs and their interconnections chronologically ordered exchange of ideas from single author to unlimited readers real time not journal time (ie. daily or weekly) has links and comment fields

9. WIKIS a webpage or set of webpages that can be easily edited by anyone with access collaborative tool now available as an option in major software packages has a history function to view previous versions ease of use vs. malicious editing and vandalism though things can be quickly corrected

10. WIKIS Wikipedia the most well-known wiki accuracy is comparable to a regular encyclopedia disputed though http://www.wikipedia.org/ SFU related wikis: SFU Cognitive Science http://www.zanyt.com/cogs_wiki/index.php?title=Welcome LIDC http://wiki.lidc.sfu.ca/HomePage

11. TAGGING a tag is a keyword attached to a digital object very often used in searches eg. Flickr and YouTube

12. TAGGING searching Flickr for “fat” and “cat” tags will give results showing a overweight cats or other things called “fat cat”, such as the “Fat Cat” pub…

13. MULTIMEDIA SHARING areas and services that facilitate the sharing and storage of digital media eg. Flickr, YouTube, etc. distribution on a massive scale productions are high quality, but on low cost digital media technology

14. RSS RSS = Really Simple Syndication allows a user to subscribe to a “feed” and gain content thru a subscription RSS icon up-to-date information from websites, blogs, etc. without having to go to the original source common in news websites or other websites that are continually updated with information

19. THE SIX BIG IDEAS BEHIND WEB 2.0 from What is Web 2.0? Ideas, technologies and implications for education by Paul Anderson Individual production and User Generated Content Harness the power of the crowd Data on an epic scale Architecture of Participation Network Effects Openness

20. 1. Individual production and User Generated Content content added very easily to media sites eg. MySpace, YouTube, etc. content can be searched with tags people writing blogs and contributing to wikis user generated content also called content self-publishing, personal publishing, self-expression. new, cheap, accessible and quality tools lower entry bar eg. digital cameras, mobile phones with devices, video cameras, etc. similar to computers, printers and paper desktop publishing in early 80s “ everybody can do it, but not anybody can do it” talent still distinguishes

21. 1. Individual production and User Generated Content existing/traditional media sources are threatened and are adapting shows now have podcasts or can be downloaded from iTunes store RadioHead, NIN, etc. now giving away music redefinition/reinterpretation of audience more authors than readers blogs that are never read… contributors are driven by attention rather than financial motives threats to structure and authority traditional media sources are structured, edited and sources verified not like the internet…

22. 2. Harness the power of the crowd collective intelligence information = intelligence (?) as group can be collectively more intelligent than a single individual eg. ask the audience on who wants to be a millionaire hazards: “ groupthink”, lack of a deep level critical thinking, etc. “ crowd sourcing” “was coined by Wired journalist Jeff Howe to conceptualize a process of Web-based out-sourcing for the procurement of media content, small tasks, even solutions to scientific problems from the crowd gathered on the Internet.” eg. websites with stock materials, like shutterstock.com, istockphoto, etc. threat to existing photographic professionals content not good, but good enough eg. websites like Innocentive match scientists with R&D clients

23. 2. Harness the power of the crowd Folksonomy: “ Folksonomy is the result of personal free tagging of information and objects (anything with a URL) for one's own retrieval. The tagging is done in a social environment (shared and open to others). The act of tagging is done by the person consuming the information.” VanderWal, 2005, blog entry. tags are meant to connect, not categorize tags are created in a social context with people using their own vocabulary and meanings (relative to a community) tags are not created in formal taxonomy nor have standard meanings remember the search for “fat” and “cat”…?

24. 2. Harness the power of the crowd example: consider a search on YouTube.com for “evan” this can mean: A trailer for the movie “Evan Almighty” The “Evan” from the movie “SuperBad” And many more “evan”s… each person adding a video to YouTube.com puts an “evan” tag with it…(among other tags) YouTube.com does not control or categorize the content to have a standard meaning for “evan”

25. 3. Data on an epic scale information, data, etc. generated is staggering in its quantity with multiple sources and contributors ‘ datafication’ of the world services exist to collect and manage this data eg. Google the use of these services makes these services smarter data mining techniques eg. the monitoring of collective buying habits to make suggestions to individual users eg. Netflix, Amazon, etc. data becomes a resource privacy issues and implications who owns this data?

26. 4. Architecture of Participation how a website is designed affects the participation eg. pay vs. free eg. classmates.com vs. facebook.com -eg. amount of steps to register with website a website can get better the more a person uses it it adapts to the person eg. recommendations from a website, or a website connecting likeminded people open-source software ie. the sharing of ideas and content for reuse and new combinations

27. 5. Network Effects “ The Network Effect is a general economic term used to describe the increase in value to the existing users of a service in which there is some form of interaction with others, as more and more people start to use it” eg. FaceBook not all users have the same value some are more valuable to user than other eg. family, friends, acquaintances, co-workers, strangers, etc. the flipside: the lock-in to technology as more people use a certain product or service, it becomes difficult to switch to another product or service (that may be better) because there a few people to share with eg. VHS vs. Beta eg. Blu-ray vs HD-DVD it shows the needs for interoperability

28. 5. Network Effects many things on the internet are unequal there are artificial barriers that make it easier for some and extremely difficult for others ie. popularity, promotion, position on search engine, placement on webpage, etc. there is a counter-movement to with the “democratization of the tools of production” as amateurs are able to flood the internet with content

29. 6. Openness “ The development of the Web has seen a wide range of legal, regulatory, political and cultural developments surrounding the control, access and rights of digital content.” you don’t have to pay for stuff now! eg. music, movies, software… web 2.0 stresses openness open standards, open-source software, free data eg. the push for Open Document Format (or ODF) all to be used and reused freely for the common goal of open innovation eg. FireFox and its plug-ins

30. EDUCATIONAL AND INSTRUCTIONAL ISSUES: “ In these scenarios, education is more like a conversation and learning content is something you perform some kind of operation on rather than ‘just’ reading it.“ Problems: users are in a 24/7 environment economic divide among user’s home resources differing skill levels privacy and plagiarism issues of online collaborations shared authorship and assessments the lack of understanding about student learning modes and social aspect of the software

31. EDUCATIONAL AND INSTRUCTIONAL ISSUES: the redefinition of the teacher/student structure from teacher-centered instruction to student-centered learning/creating how does education deal with the traditional hierarchies of knowledge and the new web 2.0 reality?
