Virtual Collaborative Learning: A Comparison between Face-to-Face Tutored Video Instruction (TVI) and Distributed Tutored Video Instruction (DTVI)

Tutored Video Instruction (TVI) is a collaborative learning methodology in which a small group of students studies a videotape of a lecture. We constructed a fully virtual version of TVI called Distributed Tutored Video Instruction (DTVI), in which each student has a networked computer with audio microphone-headset and video camera to support communication within the group. In this report, we compare survey questionnaires, observations of student interactions, and grade outcomes for students in the face-to-face TVI condition with those of students in the DTVI condition. Our analysis also includes comparisons with students in the original lecture. This two and a half year study involved approximately 700 students at two universities. Despite finding a few statistically significant process differences between TVI and DTVI, the interactions were for the most part quite similar. Course grade outcomes for TVI and DTVI were indistinguishable, and these collaborative conditions proved better than lecture. We conclude that this kind of highly interactive virtual collaboration can be an effective way to learn.
