Web 2.0 is essentially an increasing range of software that supports a variety of technologies for open and collaborative communication, learning and creativity. Discuss. Over recent years the internet has undergone an intense transformation. The current technological era has evolved, with second generation technology and software influencing how we access and utilise the internet. This second generation software has resulted from the fairly recent transformation from Web 1.0 to Web 2.0. This essay will look at this transformation by first looking at the difference between Web 1.0 and Web 2.0, and the key characteristics of each. By looking at this transformation first, it will then be feasible to look at the various applications and software examples within the Web 2.0 sphere, and how this has enhanced collaborative communication, learning and creativity, particularly in reference to education. Web 1.0 is often referred to as first generation technology, or the first wave of the World Wide Web or Internet. What this involved is the simple process of extracting information from static sources on the internet. Examples include online encyclopaedias and personal websites. Most things were in plain text and in read-only format; therefore interaction wasn’t a significant aspect. However, in recent years, there has been a development of the internet to Web 2.0, or second generation technology. ‘Web 2.0 refers to a perceived second generation of web-based communities — such as social-networking sites, wikis and folksonomies — which aim to facilitate collaboration and sharing between users’ (Wikipedia, n.d.). This wave of the World Wide Web holds primary importance on online interaction and collaboration as a means of sharing information, as opposed to simply extracting information from static, plain text websites. Examples include blogs and wikis. With increased development of various software tools like these, this new generation of the internet has enforced the idea of an online community, with concepts of constructivism and connectivism, which will be later discussed in this essay. It has been asserted that due to the establishment of the Web 2.0 sphere, the web is now ‘alive’ (Levy & Stone, 2006). Levy & Stone (2006) further state that ‘what makes the Web alive is, quite simply, us’. This implies that we as consumers, online users and participants have played an active role in the development of Web 2.0, as over time there has been an increased need to sharing capabilities. Furthermore, when Web 2.0 was initially developed, one of the founding ideas as indicated by one of the early promoters of Web 2.0 Tim O’Reilly, ‘the central idea is harnessing collective intelligence’ (Levy and Stone 2006). Therefore, by using various software tools to promote learning and creativity, the internet provides a space for users to collectively share and extract information and knowledge, by creating a collaborative environment online. Popular examples of online software tools which epitomise the intent of Web 2.0 are social networking websites like MySpace, Facebook and Flickr. These softwares involve users to create a web page in which they create a profile for themselves, post journal entries, personal information, photos, videos and web links, add friends and receive comments. By having the capability to do all these things, social networking websites establish what is known as online communities. Using Web 2.0 software like MySpace, communities can be established by various users online sharing a common interest and becoming friends. It has been suggested that online communities depend upon social interaction and exchange between users online, and this emphasizes the reciprocity element of the unwritten social contract between community members, as Web 2.0 is essentially characterized by these online communities (Wikipedia, n.d). These online communities thus provide the avenues, and primarily the space, for social collaboration and online sharing between users, which are key characteristics of the Web 2.0 phenomena. Linking on from this idea of communities, is a crucial element of Web 2.0 that can be related specifically to education and learning, that being the notion of social constructivism. As identified by Vygotsky, social constructivism involves a network of social collaboration; in which higher order thinking develops out of social interactions and combined experiences. Tying in all these ideas of social constructivism and online communities, and interesting software tool that would be useful for learning and creativity particularly in relation to education is a blog. The term blog was derived from ‘web log’, in which an individual can create an online space in which to publish thoughts, information and web links. However, what makes a blog different to an ordinary website is that the individual creator constantly updates the content on their blog, and external users or visitors have to ability to view their blog and leave comments for the blog’s creator. This therefore allows online discussions to occur, in which different web users can connect with each other. Creating a blog provides a useful tool for educators and students. ‘Blogging has quickly become one of the most effective learning tools in education today’. (Benzinger 2006). Using a blog for learning and creativity will allow students to post homework and assignments online, and the teacher is able to go to one place to retrieve all the students work. Also, with the comment capabilities, teachers are able to leave students comments on their work. Furthermore, a blog often consists of journal entries, so for the students a blog could be used as a domain for students to engage in reflective activity, which promotes educator Bloom’s theory of higher order thinking. Online communities can also be created through establishment of wiki’s, and can be a very useful tool in the classroom environment. A wiki is computer software that allows users to easily create, edit and link web pages. According to Wikipedia, probably the most popular wiki that has been created, a wiki is a server program that allows users to collaborate in forming the content of a Web site. With a wiki, any user can edit the site content, including other users’ contributions, using a regular Web browser (Wikipedia, n.d). For the purposes of the classroom, a wiki can provide a central place for a teacher to post work done in class, whereby students can access the work in case they miss a class. Homework and Assessment tasks, supplementary links and means of contact can all be posted on the Wiki, which emphasises the idea of information being placed in a central place. It becomes useful for teachers to provide links to online tasks and activities on the wiki, as another means of centralising educational activities into the one place. Furthermore, the wiki can be used as a sharing domain, because as the wiki allows a number of different editors and collaborators, students can post ideas and feedback on the wiki, in which all and the teacher will be able to access. There has been establishment of a new term to describe the advancement of social constructivism in particular relation to Web 2.0, known as ‘connectivism’. According to Siemens (2004), connectivism primarily involves learning and knowledge resting on a variety and diversity of opinions, as well as learning being a process of connected specialised nodes or information sources. So ultimately, connectivism relies upon a mixture of knowledge received from a collaborative and communitarian system, in which Web 2.0 provides the framework for this collaboration to occur. Users have to ability to share information with other users online, as new information is continually being required and these connection enable users to learn more, which are more important than our current state of knowing (Siemens 2004). Sharing information online is another crucial aspect of Web 2.0 in coalition with the idea of online communities and social collaboration. Social bookmarking websites are also crucial for this Web 2.0 principle of sharing information. One such example is del.icio.us. This software tool enables users to save their favourite webpage’s onto the online domain, thus giving them the ability to access their saved webpage’s wherever they have access to the internet. This becomes a useful and significant tool in Web 2.0, as users have the capabilities to save all their information in the one central place for easier accessibility. This placing of information and knowledge into a central place brings into the picture a domain, developed by Google, known as iGoogle. This is an individually customised web page, in which users are able to add web feeds and links, interesting backgrounds, and collectively centralise information to be accessed in the one place. Similar to social bookmarking, iGoogle creates a web page, password enabled, where information can both be saved and streamed into the one place. Furthermore, you can access your documents anywhere at any time and work on them as you normally would.In conclusion, Levy & Stone (2006) provide a useful summary describing how Web 2.0 has transformed the internet and how we utilise its software.
‘Less than a decade ago, when we were first getting used to the idea of an Internet, people described the act of going online as venturing into some foreign realm called cyberspace. But that metaphor no longer applies. MySpace, Flickr and all the other newcomers aren’t places to go, but things to do, ways to express yourself, means to connect with others and extend your own horizons. Cyberspace was somewhere else. The Web is where we live’ (Levy & Stone 2006).
Overall, Web 2.0 has proved to be an innovative and significant transformation to the World Wide Web, in which being online means engaging technologies which require a collective and collaborative effort, promoting learning, communication and activity, and as such, provides useful tool for the future of education.
