This problem set begins by asking students whether or not they are able to see video content. If they are not, they are removed from the study and given a traditional problem set with text feedback. For students who are able to access video content, they are randomly assigned to receive either video feedback (experimental condition) or text feedback (control condition). Within the experimental condition, students received a video of another student solving the problem. Students only receive this feedback if they answer the problem incorrectly.
