Abstract: This study reports on students’ perceptions and behaviors regarding the use of Wikipedia and EduTechWiki (public wikis) for a collaborative assignment in a graduate level technology and literacy course. The results demonstrated that initial perceptions of public wikis were mostly negative and apprehensive, with students’ expressing anxiety and fear at the thought of contributing to a public document. During the assignment, students commonly reported frustration and difficulty with the wiki interface. After completing the assignment, students’ reactions were overwhelmingly positive, with many recognizing the benefits of public wikis in the K-12 classroom as either a resource or collaborative tool. Pedagogical practices are recommended for successful implementation of teaching training learning activities using public wikis.
