摘要：Video is a rich medium that conveys more social cues than text. Use of video in an online discussion forum therefore has the potential to increase social presence in online learning environments. This experimental study compared a group using video for a portion of the required discussion posts to a group using only text in an online undergraduate course. While there was a correlation between perceived social presence and satisfaction with the course, there were no significant differences in perceived social presence or course satisfaction between the two groups. Open‑ended comments revealed a mix of positive and negative reactions to the use of video. This study highlights the need for continuing research on the use of video in online discussion forums to assess the benefits of video relative to its possible negative effect on “anytime, anywhere” flexibility.
