What is the most appropriate time to provide feedback to a group of students who are making non-lethal errors during a scenario?

Providing feedback immediately after the errors is the most effective approach because it allows the instructor to address the specific actions while they are still fresh in the students' minds. This timing leverages the “teachable moment,” where students can directly correlate the feedback with their actions during the scenario.

Instructors can clarify what went wrong and guide students in understanding the correct procedures or techniques. Immediate feedback also helps reinforce learning by allowing students to reflect on their decisions while they are still engaged in the learning process. This method keeps the learning contextual and relevant, which can enhance retention and application in future scenarios.

Feedback at the beginning of the class does not allow for specific engagement with the students' current experiences or mistakes, which could make it less effective. Offering feedback during the practice sessions could interrupt the flow of learning and may distract students from completing the exercise. Providing feedback after they’ve finished the scenario can delay the learning experience and may result in less impactful corrections, as students might not recall the details of their actions as vividly.
