This document discusses using wikis in the classroom. It notes that wikis can improve learning by putting learning in students' hands with guidance and encouraging collaboration and engagement. Wikis allow for multiple authors, sharing, and collaboration. Students generally like wikis as they allow 24/7 access to materials and a sense of ownership. Some challenges are that students may be uncomfortable with collaboration, self-directed work, or critiquing peers. Best practices include providing training, clear expectations, modeling collaboration, and choosing a multifunctional platform.
