Hi Betty: For me, assuring the course objectives, student learning objectives, and skill check-offs are met with as close to mastery as possible. These days, so much is compacted into tighter time periods, I think a lost "art" is the benefit of repetition Ookay, practice). Whatever the term, I think as often as possible, students should be given opportnity to demonstrate and repeat demonstration of all essential skills. Repetition builds performance mastery. This is also helpful for recall oriented facts. Regards, Barry
