This research investigated factors that predict preservice teachers’ intentions to use Web 2.0 technologies in their future classrooms. Results indicate that positive attitudes and perceptions of perceived usefulness are significant predictors of preservice teachers’ intentions to use Web 2.0 technologies. Additional findings indicate that preservice teachers intend to use blogs, wikis, and social networking in their future classrooms to improve student learning, student-student and student-teacher interaction, collaborative learning, student writing ability, and sharing content knowledge.
