Which of the following Web 2.0 tools is most effective for collaborative learning in an e-learning platform?

Correct option is A

A Wiki is a collaborative tool where multiple users can contribute to and edit content. It fosters collaboration, allowing students to work together and build knowledge over time. This makes it one of the most effective tools for collaborative learning on an e-learning platform.

Information Booster:
Blogs are used for individual expression and reflection. Podcasts are great for delivering content but lack interactivity. Video conferencing allows real-time communication but is less effective for collaborative content creation.

Additional Knowledge:
Wikis also allow asynchronous collaboration, meaning students can contribute and edit content at their convenience. This makes wikis particularly useful for group projects or research-based assignments. Moreover, tools like Google Docs or Notion also fall into the category of collaborative tools, with added features like real-time editing and comment tracking.
