Blog

Definition

• A blog or weblog is a web-based application where authors write regularly some articles such as in a journal or diary. Entries are displayed in reverse chronological order.

• "Weblogs provide a format for critiques of other Web materials along with various personal touches. They are structured like journals, with their segments identified by time and date. . . . The weblog format allows developers (often known as "bloggers") to work either alone or in teams. It supports a wide range of personal expression and interaction as individuals access and comment on one another's weblogs.. . . Along with critiques of various articles and web sites, weblog development can also incorporate "day-in-the-life" narratives and other forms of personal information." (Jo An Oravec)

Types of blogs

• Typical single user blogs (see below)
• Embedded blogs in portals (e.g. in C3MS, LMS or CMS systems
• Collective blogs, e.g. news engines or the default module displayed in a C3MS

Architecture of a typical single-user blog

Generally a weblog is composed by different elements:

Articles

A weblog engine enables the possibility to enter a new article via a web form. User can write a title, an excerpt and the body of the article. He can also choose the categories in wich he will fill the new article. The user can always modify or edit the previous articles. The visitors can post comments to articles.

Each article (or post) is generally composed by different elements:

• Title
• Date of writing/posting
• Author
• Content
• Permalink of the article, i.e. the URL of the full article.

Most better blogs also include:

• Categorie(s)
• Number of comments plus a links to open them. Note however, that due to spamming problems, many bloggers have commenting disabled.
• Trackback (and/or number of trackbacks), i.e. links to other sites that refer to this entry

TrackBack “is a mechanism for communication between blogs: if a blogger writes a new entry commenting on, or referring to, an entry found at another blog, and both blogging tools support the TrackBack protocol, then the commenting blogger can notify the other blog with a "TrackBack ping"; the receiving blog will typically display summaries of, and links to, all the commenting entries below the original entry. This allows for conversations spanning several blogs that readers can easily follow.” ([1])

Main page

Recent Articles (main block)

The main page displays the most recent articles sorted into a reverse chronological order. A variant or similar application are news engines where only the trailers of articles are displayed.

Sidemenu

Generally, depending on the layout choosen, we can find several navigational links:

• monthly archives
• category archives
• search form
• blogroll (a list of blogs that the author reads)
• Sometimes RSS feeds from other blogs (usually just the title)
• An "RSS" button that provides the URL of the blog's RSS export(s).
• A button that lists blogs that link to this blog (e.g. via Technorati search)

How To / Installation

If you have a hosting, you can install a standalone plateform (we have dressed a small list of the most important Open Source blogging tools). You can also open a blog without any installation. You can find a lot of commercial solutions (Google is your friend).

Popular open source softwares

1. WordPress: based on PHP/MySQL is one of the best blog engines. The new version of WordPress integrates a small CMS
2. MU WordPress: based on WordPress this version enhance some functionalities. The administrators can create more blogs with one installation. WordPress permits to have only one blog at time
3. TextPattern: based on PHP/MySQL
4. DotClear: french blog engine
5. b2evolution: like MU WordPress
6. Nucleus: multi-blog-CMS like MU WordPress (PHP/MySQL)
7. Roller Weblogger: like MU WordPress but based on Java

Search engines

• Traditional search engines like Google web search rather do a bad job with blogs (since blogs are focused on what is new and not contents that are referred to by many sites over a very long times). Therefore rather use specialized services like:
• Technorati, see Wikipedia:Technorati
• Feedster, see Wikipedia:Feedster
• Goggle Blog Search

Educational Usages

Draft

• Technically speaking, there is a difference between using a blog among other tools within a design, or wether it is the "center stage" medium. DSchneider uses blogs in his own teaching just as little reflection tool within his C3MS project-based learning model.

• A blog can be given to individual students, to groups or to the class as a whole. Note: if students use multiple blogs, make sure to understand how the "blogsphere works" (i.e. learn about how blogs connect with RSS and trackback mechanisms, e.g. see the [Wikipedia article] for technical details.

Typical educational use includes, for example:

• as a note taking tool in classes
• to collect resources and ideas (with small comments and reflections). That is actually what most "academic" blogs do. E.g. a very fine "world class" example is Pasta & Vinegar.
• as note taking tools for (before/during/after) field trips, e.g. to write down questions, observations, reflections, etc. See inquiry learning.
• as a (class or project) management tool (instead of a forum or any other writing tool).
• as a collaborative tool {{comment | this is too vague ..}
• as a news tool for a school or even a class
• as a website (instead of a CMS tool or HTML pages)
• as reflection tool
• as discussion tool (either via the comment tool or within a multi-blog setup with trackbacks)
