One of the more difficult aspects of teaching - in-person or online - is getting learners to accept feedback that can influence future responses. First, to be effective, feedback needs to be rather prompt when the issue is still present in learners' minds. Even so, humans do not generally like to hear corrective comments. The instructor-learner relationship needs to be established so that guidance can be accepted. Learners need to be taught how to offer effective peer feedback. This could lead to self-analysis which is the likely the best feedback.
