Web 2.0 tools in education – UGC NET Question

Web 2.0 is characterised by user participation, interactivity and collaborative content creation. Wikis allow multiple users to create, edit and revise pages collectively, with change histories and discussion features. In education, they support group projects, shared knowledge bases and peer learning. Thus, a wiki platform is a textbook example of a Web 2.0 tool for collaboration.

Option A:
This option identifies wikis as platforms where many users can edit and update content, which fits the essence of Web 2.0. The dynamic, user-generated nature of wiki pages encourages participation and reflection. It transforms students from passive consumers into active co-creators of knowledge. Therefore, this is the most appropriate example in the given list.

Option B:
A static website presents information in a one-way manner with little or no user interaction. It is closer to Web 1.0, where users mainly read content. Since there is no collaborative authoring, it does not represent Web 2.0 features.

Option C:
An offline word processor can support individual document creation but lacks network-based collaboration by itself. Without shared editing or online interaction, it does not qualify as a typical Web 2.0 tool.

Option D:
A PDF document hosted on a server is usually read-only for most users. Unless additional collaborative layers are added, it does not support real-time co-authoring or user-generated content. Thus, it is not a Web 2.0 collaborative tool.
