Why Blog?

A weblog (shortened to blog, occasionally spelled web log or weblog) is a web-based publication consisting primarily of periodic articles.

Often, the word blog or blogs are used to describe an online diary or journal. They are also seen as repositories for information about the state of mind of the blogger and have been very helpful for communication or information dissemination of the nature of his or her work and the day to day activities he or she engages in.

The first weblog was the first website, http://info.cern.ch/ (the domain name no longer exists), the site built by Tim Berners-Lee at CERN. Today, there are many educational applications of blogs. Students can use weblogs as records of their learning and teachers can use weblogs as records of what they taught.

For example, a teacher can blog a course, recording day-by-day what was taught, including links to internet resources, and specifying what homework students are required to carry out.

This application has many advantages: (1) a student can quickly catch-up if they miss a class; (2) the teacher can use the blog as a course plan; and (3) the blog serves as an accurate summary of the course that prospective students or new teachers can refer to. (http://en.wikipedia.org/wiki/blog)
