A blog (shortened form of web log) is an online journal. In a learning context, a blog can be used by learners as a way to reflect on their learning experiences. Depending on how the blog is configured, the postings may be available to be read by fellow learners and/or tutors, who can then add their own comments to any posting. A blog may also be maintained by a tutor, to provide an ongoing commentary, reflecting on events occuring during a course.
