Acknowledge students positively
I have found that a student will respond as he is acknowledged. If the instructor has a positive attitude and acknowledges the student pleasantly at all time, in the hall ways or at the door, and even away form the campus. The word gets out and students come in to the class with the expectation that this is going to be a pleasant experience, and they will like the instructor before they have formally met. It is contagious try saying good morning or hello to every one you pass, it will come back around
