Wikipedia definition - A weblog (now more commonly know as a blog) is a web-based publication consisting primarily of periodic articles (normally in reverse chronological order).
Merriam-Webster definition – website that contains an online personal journal with reflections, comments and often hyperlinks provided by the writer. The word blog originated from the words “web and log”. The most simplistic view of a blog is that it is an online diary. A user can come to their blog and put in what ever they are thinking about. There are many blogs that are out there that do just that; talk about their day, their pets, job or many other topics.
For education there can be many other opportunities for students. If created and fostered correctly, students can use blogs to journal, write stories, share information. As a teacher or administrator a blog can be used to share information with parents, make announcements or create a forum for discussion.
