  1. Set Clear Expectations
    Before setting wiki guidelines and sharing them with your students, consult your school’s policies on social media. Provide students with written guidelines that must be adhered to. Let students know that if they publish inappropriate content, there will be consequences. Asking students to sign a contract is also an option.
  2. Start Small
    Take baby steps. Everyone will benefit from gradually increasing wiki use in the classroom. By starting small, teacher’s can stay on top of monitoring classroom wiki, thus remaining in control.
  3. Ask for Help
    Although wiki is fairly easy to use, there are times when you’ll run into stumbling blocks. Ask for help when you don’t understand something. You’d be surprised at much your students and colleagues might know about wiki.
  4. Read other Wikis
    As a class and individually, explore other classroom wikis. This will give you ideas and inspirations for your own wiki pages.
  5. Let Wiki Work for You
    Wiki is more than just a learning tool for students; it’s a communication tool for teachers. Use wiki to keep parents informed and post assignments and other class related content. Your wiki page is easily edited and updated so there’s no more need for a last minute trip to the copy machine.
  6. School-wide Wikis
    Use wikis to showcase field trips, class events and school-wide events, such as the prom or last week’s football game.
  7. Pinterest
    This site has a wealth of information on wiki for the classroom. Simply type in a search term such as "wiki tips for the classroom".  If you don’t already have a Pinterest account, learn more about it through sims 3 cc finds tumblr.
  8. Collaborate
    Do lots and lots of group work. Create assignments that require students to work together, continuously communicating as part of team as they would in the real world.  For example, a media class can work in teams to create an advertisement for a product of their choice that involves print and/or video.  For a science class, have students work together as a research team investigating the sudden drop in the local wolf population.

    Using a written set of guidelines, teachers post topics that students can argue by using wiki online forums. Teachers will monitor the discussions/debates while students learn online debate etiquette.
  4. Create a Collaborative Story
    Start with one sentence pulled from a hat, “The girl looked beyond the dusty field and saw a team of horses approaching, their riders hands tied behind their backs.” From here, students add and edit text to create a story. Set a minimum amount of words each student must submit. Chances are, you’ll actually have to set a maximum amount of words.

  10. Fact Checking
    The reason why wikis is often blacklisted as a reputable source is because not everyone who contributes to a wiki page is an expert. Keep your students on their toes by assigning them to fact check each other’s work.
