The learning benefits of peer assessment and providing peer feedback have been widely reported. However, it is still not understood which learning activities most facilitate the acquisition of feedback skills. This study aimed to compare the effect of a modeling example, i.e., a model that demonstrated how to give feedback, on the acquisition of feedback skills. The participants were second-year bachelor students in pedagogical sciences (N = 111). They were assigned randomly to a "practice condition," in which they practiced giving feedback on oral presentations, or a modeling "example condition," in which a teacher demonstrated how to give feedback on a good and a bad presentation. Students then gave feedback to a presenter in a video (direct feedback measure). One week later, they gave each other peer feedback on oral presentations (delayed feedback measure). On the direct feedback measure, students in the modeling example condition used assessment criteria more often in their feedback, and produced significantly more overall feedback, and significantly more positive and negative judgments than students in the practice condition. There was no significant difference in the amount of elaboration and feed-forward between the two conditions. On the delayed feedback measure, there were no significant differences between the two experimental conditions. The results suggest that, at least in the short term, a modeling example can stimulate the use of assessment criteria and judgments in feedback. The results and implications for future research and practice are discussed.
