The document discusses a study on how teacher librarian candidates use Web 2.0 tools in their personal, professional, and academic lives. A survey of 100 candidates found their learning ecology was limited mainly to social networking, media sharing, and communication tools for personal use. Few used more advanced Web 2.0 tools like social bookmarking and wikis. The study suggests expanding teacher candidates' learning ecologies by incorporating Web 2.0 engagement activities in their programs to increase technology adoption.
