Feedback has been described as the "cornerstone" of effective teaching (Cantillon, 2008) and is essential for performance improvement. Feedback, whether verbal or written, should include both positive and constructive guidance for maintaining and improving knowledge, skills, and attitudes with an emphasis on improvement strategies. "Without feedback, mistakes go uncorrected, good performance is not reinforced and clinical competence is achieved empirically or not at all" (Ende, 1983).
