Kathy, You've touched on an important area. One great attribute an instructor can possess and project is that of being approachable. When students feel they can ask questions freely (and repeat the same question again if they don't understand), or ask for help, or seek and receive advice, or freely communicate, the open channel to reaching students has been improved. No one is ever at 100% of approachability, but it's worthwhile to commit to improvement, if we see value in doing so. Barry Westling
