Definition
A wiki is a powerful collaborative tool that allows users to add and edit content online. User can also easily create new pages. If necessary it's possible to add some permissions to the pages (lock pages or only identified users can modify the content of a page).
What is a wiki ?
Technical features
On line editing with history
- Explanation by example: This website is powered by a wiki. If you want, you can modify this page, changing words or sentences.
- On most wikis, all modifications (or at least a representative sample) are stored and you can always undo all the modifications.
Editing
- Editing content on a wiki is usually very simple, users have to learn a small syntax
- There is no standard Wiki syntax. Each Wiki Software has its own, although some types of Wikis are very close.
- However, some wikis like this one use an increasingly complex syntax, e.g. for this mediawiki see How to edit a page). Users still have the option to work with a very small subset, as demonstrated in the Wikipedia Chatsheet
Wiki Management
- Generally, most sites require that some editing rules for style are respected. The goal of these rules are to standardize organization of contents within a page or throughout the wiki, in oder to make both knowledge retrieval and production easier.
- Frequently, Wikis also adopt editorial charts. Wiki administrators have to pay attention to both new new users having sometimes difficulties to adapt to the wiki paradigm (everybody can do what they want respecting other's work) and persons that do not easily fit into a local "spirit".
There is an increasing problem with vandalism and therefore many Wikis require at least a login to edit. Educational wikis now tend to exclude externals from editing.
Educational usage
- wiki as tool for inquiry-based learning designs (e.g. Lombard)
- wiki as a collaborative content management system
- wiki for collaborative writing (see collaborative learning, writing-to-learn, CSCL, inquiry-based learning, ABAHCOCOSUCOL)
- wiki as a resource repository
- wiki as a project/class management tool (see project-based learning)
- wiki as a website
- wiki as hypertexts (see cognitive flexibility theory)
Wiki software and installation
Installation
Most Wiki installations require some system administration skills. Usually a Wiki runs as a web-based Internet service and you therefore need to have the following compontents already installed:
- a webserver
- some scripting language, e.g. PHP
- most of the time, a database server like MySQL.
