This document discusses the evolution of the World Wide Web from Web 1.0 to Web 2.0. Web 1.0 (1994-2004) allowed for basic HTML publishing of read-only content that was updated by webmasters. Web 2.0 (2006-present) enables creativity, communication, and user-generated content through social media platforms, user-uploaded content, and greater interactivity. The document also provides examples of online tools that can be used to teach English, such as Wordle for vocabulary, ImageChef for images, and Skype for video calls. It emphasizes that teachers should facilitate student-centered and hands-on learning using these new technologies.
