Blogs allow students to collaborate and contribute to a course. There are individual blogs for each student, course blogs for all students, and group blogs that can be shared between group members. To create a blog, go to the Control Panel and select Course Tools > Blogs. You can then add a name, description, and set availability and permissions. Blogs can be used for students to comment on each other's work, and entries can include text, links, images, videos, and attachments.
