Wikis combine technology and collaboration. Having this combination is not only just essential for the educational environment, but for everyday life as well. Collaboration allows for a greater perspective on a topic, as well an expansion of ideas. It allows students to develop teamwork skills, something that is vital for their futures. Building a wiki with your class allows your students to work together, creating a site that covers the material in a way that is helpful to them and that they can be proud of.
In addition to building teamwork skills, a class-built wiki allows students to present information in a way that they can understand. It is also an effective tool for students to use a reference guide, both throughout the school year, but also in later course work. And because of the collaborative effort, students will also be exposed to different view points, allowing for a deeper, richer understanding of the material.
As with all technology-based classroom activities, there are some concerns. Richardson mentions that with the use of wikis, the role of the teacher becomes a bit vague. It can also be difficult to assess student work, since any of the students can add to or edit a wiki entry. Content becomes an issue. It can be difficult to find a balance between allowing students to explore and create, but also ensure that they are creating entries that are relevant to the class.
