A wiki is a website that allows visitors to easily add, remove, and edit content, making it an effective tool for collaborative authoring which allows students to construct knowledge. There’s no need for software, all you need is an Internet-connected computer to contribute, which makes a wiki a great tool for the classroom that’s open 24/7. Uses in education are abundant. Here are a few examples from our own backyard:
- Regions of the United States, a wiki project starting in January for collaboration between students in 4th grade classrooms in Oak Park and students in classrooms across the US.
- Names of the Constitution, a wiki for middle school students, created by Ashley Kannan
- The Road to Revolution, a wiki for 5th grade students featuring an interactive simulation.

We are excited to study regions with students in other places. Pennsylvania Pals
Good ideas here. Hope to join the projects.
