A blog can be viewed as an online journal of a particular owner/author. It is updated whenever the author has something to share (weekly, daily, hourly). Blogs do have spaces for opinions of readers to be posted, but readers do not alter the initial post.
A wiki is a website that is meant for multiple people to update in real time from all around the world. Wiki entries/articles represent a consensus, but again there is an area for discussion and comments.
Wiki's can host a blog, but not vice versa.
Blogs:
- Usually a single author. Sometimes can have multiple contributors,
- Author posts, user comments,
- Opinion Sharing ,
- One-to-many content.
Wiki:
- Multiple Authors,
- Edited by a group or team,
- Contains links to other Wiki pages,
- Continuousy changing and growing rapidly,
- Many-to-many communication.
Both blogs and wikis can be used in online courses. This blog was started to serve my journal while discovering new tools to use for online learning in my Tech Tools ION course. It follows along as I learn more on the topic.
Wikis are probably more useful for group projects. I place to share material created by group members as well as a place for discussion and editing to occur.
I personally really like blogger for blogs, mainly because I familiar with the tool plus it is linked to my google account. For wikis I use pbworks, another very intuitive tool.
This article, by Bill Ferriter is a great resource to find out how to use blogs and wikis in education.
I have not really used blogs and wikis for educational purposes (except as a student, with mixed results). Some problems I see with this technology is that it takes a student away from the main course website, in addition if the group working on the wiki is large it can become quite cumbersome. I will post more on this topic later when I have more experience actually using it as an instructor.
