摘要：In laboratory study environments, dialogue-videos, or videos of a tutor and a tutee solving problems together, have been shown to more effectively improve student learning than monologue-videos, or videos of tutors solving problems alone. Yet, few studies have replicated these findings in the context of authentic university classrooms. Here, we investigate the impact of dialogue-videos, and more specifically the effect of errors made by tutees in dialogue-videos, on student learning in the context of an undergraduate biology course. To understand why, we investigated students’ effort spent on watching videos, perceived influence of dialogue-videos, and worksheet completion rates. We found that higher-performing students perceived that they used the dialogue-videos to review content. We also found that higher-performing, but not lower-performing, students learned better from dialogue videos where tutees made errors. We also discuss the complexities of replicating laboratory studies in the classroom and implications of our findings.
