Effective feedback focuses on strengths. I know this, and I try to practice it. Unfortunatly, I still find it quite a challenge to stay strength-focused while trying to discuss areas of weakness. We're taught to "sandwitch" criticism between two compliments. While that may soften the blow, it does nothing to make an effective plan for change. Identifying what the instructor does well needs to be more than a sugar coating; it needs to be part of the plan for improvement. That is an area I need to explore much further.
