Wikipedia

Wikipedia is a free online encyclopaedia and is a great example of a Web 2.0 tool. This site allows individuals to post or share their knowledge and to expand on what others say.

This is a great tool in education because it allows students to look up new words, people, or ideas and have a quick, simple understanding of the subject. This web 2.0 tools would best benefit learners such as, solitary learners, learners with mid to high reading levels, as well as learners that are reading and understanding above their grade level. This tool would benefit division two students (grades 4-6) in the elementary level most, but has no age restriction.
