Hi Joseph, By letting the students know from the very beginning of the class what the expectations are and the work that they have to do to get through successfully you have set goals for the students. By using the individual approach you are enabling the students to learn within their comfort range while developing the their skill in the area of polishing. I am interested in your comment about each person developing his/her own stroke or pressure in polishing. In your field is this a characteristic of a top polisher? Do student develop stroke and pressure skills that set them apart? If so it sounds like their work could be recognized by finish polish they put on their work? This would be if you will like their signature. Sounds like you have many challenges as an instructor as you facilitate the development of the expertise of your students. Keep exploring new ways of presenting the content and skill development and you will do well in the classroom. Gary
