Anyone with any instructional time at all knows that every new pilot looks at the panel too much and has to be taught how to scan outside. It's perfectly normal and looking out is just another one of the skills needed to be learned.
If the instructor teaches them attitudes and movements properly and their relationship to controlling the path of the airplane correctly they will look outside for almost all of their visual clues.
Looking at the instrument panel as their main clues for airplane attitude is not perfectly normal unless they came to their first lessons with an understanding of the relationship of each instrument to the attitude or performance change of the airplane.
Until they have at least reached the solo stage of flying the only instruments they should have available to look at is the airspeed, altimeter and the T&B or turn co-ordinator.
