Blogs can be used as a place for collaborative learning on projects. Not only can each student in the group contribute to the blog, experts from the global community can also contribute, deeply enhancing the curriculum. The Secret Life of Bees is a great example of highschool students using a blog to study a novel and contacting the author for her answer to their questions.
At first, I thought this collaborative use of blogs for learning would be beyond early primary students because their typing, reading and writing skills are still limited. I wonder though, could Kindergarten and grade one teachers begin this type of blogging using one blog for the class, with the teacher making entries as they would typically do on chart paper?
I think that with the teacher using a projector and screen, the students could follow the writing, while the teacher types the students' questions, thoughts and responses. Students could ask their teacher to post links they have explored as a class and could comment on those links. They could be guided to give reflective responses to be posted. They could summarize what they have learned in a unit of study. Perhaps the intended audience could go beyond other students in the class to include parents, authors, science experts, other classes in the school (perhaps their buddy class), the community or classrooms in other parts of the world. It would be exciting to receive comments and continue the conversation.
It would be important to begin by explaining the process to parents and obtaining permission for students to participate. Protecting students' identity would be necessary. See some samples of information letters and permission forms at Blogging Parent letters - Bud the Teacher's Wiki
