This document discusses several free online tools that teachers can use to engage students, including Edmodo, Kidblog, Edublogs, Collaborize Classroom, SymbalooEDU, TeacherTube, and SchoolTube. Edmodo allows student-teacher interaction and discussion like Facebook but is designed exclusively for education. Kidblog provides a simple way for younger students to collaborate through blogs. Edublogs and Collaborize Classroom support group projects and participation. SymbalooEDU and TeacherTube/SchoolTube provide educational videos that can engage students when other sites are blocked.
