Weblogs can be used by teachers, students, and parents in a K-12 curriculum. A weblog is a webpage that contains brief, chronological entries and can take the form of a diary or links to other sites. Teachers can use weblogs to post assignments for absent students. Parents can use them to see what their children are learning. Weblogs allow for communication between teachers and parents, such as online meetings. They can be used all day by posting updates and allowing comments. Reasons to use weblogs include sharing information, interacting with others, and expressing opinions. Popular websites for creating educational weblogs include Blogger, Edublogs, and Learnerblogs.
