Web 2.0 tools can help teach writing to adult English language learners in several ways. Tools like wikis, Google Docs, and blogs allow students to collaborate online on assignments and share work with others. Social media sites like Facebook let students communicate in authentic contexts and connect with people sharing their interests. Other tools such as Slideshare and Wikipedia enable students to develop multimedia presentations and research skills while creating content for a global audience. When used for project-based learning, these Web 2.0 technologies can engage students through meaningful opportunities to develop skills applicable in the modern world.
