Web 2.0

Web 2.0 is a metaphor that implies a paradigm shift in the manner by which web technology is used. Web 2.0 refers to the “read – write Web”; that is, users can not only read what is on the Web, but can also contribute to its contents. Web 2.0 empowers learners to generate ideas and comments online (active learning) rather than simply reading or browsing someone else’s comments (passive learning)


Online “Cloud” Software
This software, often free to use, is accessible through a web browser, and allows many collaborative editing and production functions.

The web log, or blog, is a page on the internet where people can write about anything that they please. Blogs take the form of many things: commentary, reviews, comedy, news articles, political speeches, or just plain everyday rants. The content can be anything that can be coded on a webpage. They work mainly as a personal journal that is accessed online by the writer and anyone who might stumble across the site. Blogs include text, images, links to other websites, and other media the writer wishes to add to the article. The blogs can also be commented on by the readers and reflected on by the writer.

The term Wiki is Hawaiian for quickly. In Web 2.0, wiki systems are social and collaborative platforms which encourage users to quickly edit and create online content with minimal technical knowledge. Wikipedia, the most widely-known encyclopedia around the Web 2.0 tools, is an example of wiki technology.

Because there are generally no user restrictions and no need for advanced technical knowledge or background for users to contribute contents in wikis, they are powerful tools for information sharing and online collaboration. Other useful features in wikis include content navigation, versioning, and searching capabilities. Therefore, many researchers realized the potential of wikis for adding collaborative dimension in online and blended learning environments.

Online communities
An online community is a group of people that primarily interact with each other via internet enabled communication media such as email, discussion forums or chat rooms rather than face to face interaction. In an online community, people come together for a shared purpose and are guided by shared rules and regulations of the community.
