In this study, we examined the effect of video-based feedback designed to highlight a peer engaging in effective thinking processes on self-efficacy beliefs and learning outcomes (performance on a delayed quiz). Students in an introductory statistics course participated in an online learning activity where they received feedback in one of three randomly assigned conditions: a video of a peer demonstrating the process of arriving at a correct answer (mastery condition), a peer making mistakes then self-correcting those errors before arriving at a correct answer (coping condition), or a screenshot of a peer's correct worked example (as a control). Results indicated that students who watched the mastery videos, but not the coping videos, rated their self-efficacy higher and scored higher on a class quiz taken more than a day after the feedback intervention than students who viewed a worked example. However, students in the two video conditions did not significantly differ in terms of either self-efficacy and quiz performance. The results of this study, although modest in scope, illustrate how the design of feedback could lead to noticeable differences in student learning.

Feedback is critical to learning, but some feedback is more effective than others (Hattie & Timperley, 2007). In online environments, feedback is typically outcome feedback--feedback that shows whether an answer [...]
