What? • Termed first coined in 2005 by Tim O’Reilly. • Different things to different people.
Before Web 2.0 • The earlier web is usually one-way. • There was a distinct difference between ‘the publishers’ and ‘the consumers’. • Tools available for the users are limited in features and interactivity.
So what exactly is Web 2.0 • Is it technology? • Is it social and cultural? • Is it both? If so how?
Key Ideas of Web 2.0 • Users create the contents. • The power of the crowd. • Epic Data • Architecture of Participation • Network Effects • Openness
User Contents • Movement towards allowing users to create their own contents for publications. • This trend is noticeable in media and music. • Who has the authority ‘to say’ and ‘to know’? • Motivation? Is it money or reputation? • Advantages and disadvantages? Discuss in your tutorial.
Power of the Crowd • There is wisdom in the crowd. More heads are better than one. • Is it? • This idea is supported or refined by concepts such as crowd-sourcing and folksonomy.
Data on Epic Scale • Production of consumer contents mean data is no longer ‘small’. • Companies like Google has core competencies in area of data management and networking. • These data can be shared via APIs – application programming interfaces. • Huge, sharable and ‘mash’-able data. • What are the issues in collecting data etc?
Architecture of Participation • Web 2.0 encourages community, collaboration and sharing. • Example is Wikipedia. • Equal emphasis on ‘architecture’ and ‘participation’. One supports the other and vice-versa.
Network Effects • Network effects – the more people use a Web 2.0 tool, the more its value. • Scale and topology considered by many to be key factor in the success of the internet. • This architecture connects people to their contents, people to people and contents to contents.
Openness • Related to epic data and participation. • Data is open, but to get value you have to build intelligence to make sense of the data. • Turns data into information into knowledge. • Issues such as open source, open publishing.
The Technology • A quiet revolution towards open source and independent methodologies and tools. • These are some of the words normally associated with Web 2.0: AJAX, REST, lightweight programming, APIs. • The browser is the main access point to services and tools.
Web 2.0 and Education • Sharing is a powerful method to learn. • Constructing something for others to learn is itself a very effective method to learn. • Constructionism. • The ability to synthesis is a goal in higher education, one that is normally missing in our universities. • Web 2.0 provides the tools required for this to happen.
The Tools and Services • Google is your best friend. • Find and present one Web 2.0 tool that can be used for education. • Different tool for each student. Post your tool/service name and brief description in iFolio discussion.
