Some instructors may choose to grade wiki assignments on participation only, while others may want a more detailed process: setting criteria, creating rubrics, and assessing each student's work and participation.
Assessing collaborative work is historically difficult to assess, since it is impossible to know which student contributed what material. It is possible to break down the group assignent into parts, of course, but that makes for a process that is not truly collaborative.
Wikis help solve this problem by making iterative development of the document visible to instructors. While this might make take more time, the instructor can review the history of each page to determine both individual contributions and to supervise the writing and revision process.
Moreover, wikis also provide a way for students to document the writing process and make this visible to instructors. Outlines, timelines, task lists, and group deliberations can all be kept parallel to the content pages of the wiki. This makes it possible for instructors to assess the process of writing as well as the product. Indeed, a wiki may be used only
to support the teamwork process.
The assessment process may also include rounds of peer- and self-assessment that require students to reflect on both the products and the process of their collaborative work.
Assessment rubrics are most effective when created with specific learning goals in mind. These examples should be used as guidelines for creating rubrics, and not as actual scoring rubrics.
