The document introduces several free Web 2.0 tools that can be used for language learning, including Writeboard for collaborative writing, Google Wave for online discussions, Wikispaces for creating wikis, and Wordle for generating word clouds from texts. It also discusses how teachers can evaluate student participation and work done using these tools, with a focus on completion, content, presentation method, and clarity rather than grammar. Teachers are encouraged to visit Classroom 2.0 to learn from other educators about integrating Web 2.0 tools into classroom instruction.
