What feedback explains both the error and how to correct it for the student?

The choice of prescriptive KP (Knowledge of Performance) as the correct answer is significant because it provides both an understanding of what went wrong (the error) and clear guidance on how to fix it. When a student receives prescriptive feedback, they not only learn about their mistake in technique or execution, but they also gain specific instructions on the adjustments needed to improve their performance.

Prescriptive KP is tailored to help learners by identifying the exact aspects of their performance that require change, which creates a constructive learning environment. This approach is critical when teaching complex skills, as it directly addresses the individual needs of the learner and allows for focused practice on their weaknesses.

Other types of feedback, such as descriptive KP, might outline the error without offering concrete steps to improve. Terminal feedback provides information after a performance, but it may not support immediate corrections during skill execution. Relevant feedback, while useful, does not inherently indicate how to correct mistakes. Therefore, prescriptive KP stands out as the most effective form of feedback for fostering skill development by combining error identification with actionable solutions.
