This study investigates the use of synchronous collaborative wikis in a graduate course for K-12 educators, highlighting their ability to enhance mutual shared cognition and expertise among students. It emphasizes the importance of collaborative learning environments and contrasts synchronous with asynchronous collaboration, noting the benefits of real-time communication in resolving conflicts and developing concepts. The findings suggest that such wikis foster positive collaborative experiences, creating an egalitarian environment and enabling students to effectively share knowledge and ideas.
