This study demonstrates the use of wiki technology (an editable webpage environment) to provide a virtual, asynchronous collaborative-learning environment for students for the purpose of working on course-content-focused study-guide questions. To analyze the effectiveness of this course tool, students' responses to various qualitative and quantitative questions were collected from multiple classes of various levels. Preliminary findings demonstrate that students preferred and were better able to use the wiki cooperative learning group compared with common classroom resources (PowerPoint, videos, in-class group activities, and the textbook).
