What's a wiki?
A wiki is a web site that lets any visitor become a participant: you can create or edit the actual site contents without any special technical knowledge or tools. All you need is a computer with an Internet connection. A wiki is continuously “under revision.” It is a living collaboration whose purpose is the sharing of the creative process and product by many. One famous example is Wiki-pedia, an online encyclopedia with no “authors” but millions of contributors and editors. The word "wiki" comes from Hawaiian language, meaning "quick" or "fast."
Who uses wikis?
Wikis are used in the “real world” (outside of K-12 schools) by people collaborating on projects or trying to share things online, such as family information and photos, technical information from users of a product, data from a research and development project, wine expertise, travel journals from abroad, club or specialty information, or projects like collaborative cookbooks.
Sometimes they are used for free expression, such as a youth group online graffiti space. College and university courses seem to be using wikis far more than the K-12 community right now. In K-12 education, wikis are being used by educators to conduct or follow-up after professional development workshops or as a communication tool with parents. The greatest potential, however, lies in student participation in the ongoing creation and evolution of the wiki.

W
hat is the difference between a wiki and a blog?
A blog, or web log, shares writing and multimedia content in the form of “posts” (starting point entries) and “comments” (responses to the posts). While commenting, and even posting, are open to the members of the blog or the general public, no one is able to change a comment or post made by another. The usual format is post-comment-comment-comment, and so on. For this reason, blogs are often the vehicle of choice to express individual opinions.
A wiki has a far more open structure and allows others to change what one person has written. This openness may trump individual opinion with group consensus.

Wiki ideas appropriate for most subjects and grade levels:
  • Study guides made by student groups for themselves and peers: each group prepares the guide for one aspect of the unit or responsibility rotates: one unit guide per semester.
  • Vocabulary lists and examples of the words in use, contributed by students (ongoing throughout the year).
  • The wiki as the organizational and intellectual epicenter of your class- Wiki all assignments, projects, collaboration, rubrics, etc.
  • Products of research projects, especially collaborative group projects: civil war battles, artistic movements, the American electoral process, diseases and prevention, etc. Remember that the products do not have to be simply writing. They can include computer files, images, videos, etc. Creating an organizational structure for the content is an important part if the project.
  • An annotated collection of EXAMPLES from the non-school world for anything: supply/demand, capitalism, entrepreneurship, triangles, alliterations, vertebrates or invertebrates, etc. Include illustrations wherever possible.
  • What I Think Will Be on the Test wiki: a place to log review information for important concepts throughout the year, prior to taking the “high stakes” test, AP test, or final exam. Students add to it throughout the year and even from year to year.
  • An “everything I needed to know I learned in Ms.Teachername’s class” wiki where students add their own observations of ways the class knowledge has spilled over into the “real world.” For example, a student might write about actually using a simple algebraic equation to figure out dimensions for cutting lumber or foam core for a display or write about ways that her friend shows tragic hubris and is heading toward a fall.
  • A travelogue from a field trip or NON-field trip that the class would have liked to take as a culmination of a unit of study: Our (non) trip to the Capital and what we (wish) we saw.
  • Articles by students who miss school for family trips, written about their travels on the class wiki, relating what they see to concepts learned before they left: mammals I saw on the way to Disney, geometric shapes in the Magic Kingdom, the most cost-effective lunches while traveling, etc. Remember: hotels usually have Internet access. Make the world a part of your classroom!
  • An FAQ (or NSFAQ- Not So Frequently Asked Questions) wiki on your current unit topic. Have students post KWL entries and continue adding questions that occur to them as the unit progresses. As other students add their “answers,” the wiki will evolve into a student-created guide to the topic. Example: Civil War FAQ or Biomes FAQ. You may find that the FAQ process can entirely supplant traditional classroom activities, especially if you seed a few questions as the teacher. This would also depend on whether you have consistent computer access on a daily basis, a luxury many schools do not have.
