One essential method every competent teacher should know is how to teach by progressions. Take something as simple as learning to remember a phone number. The phone companies long ago discovered that while people could not even remember a local seven digit number, they could readily recall an even longer number if it was broken up into small segments. The brain is better able to assimilate information in small chunks than in one large bite.
People learn better by using progressions, whether in history, mathematics, or any other discipline.
The PTR's teaching method uses progressions of simple building blocks to help students learn biomechanically sound strokes through a series of small, but most importantly, successful steps. The fundamentally sound standard method of teaching allows PTR pros to accommodate differences in the abilities and stroking styles of their students. A quick learner may require fewer progression steps, a slow learner many more, to reach the same level, but both will enjoy a continuous and confident advancement toward their goal. All sound tennis strokes are based on certain laws of physics and biomechanics. This teaching method builds upon the elements that science tells us should be common to all tennis strokes, while allowing for each individual's preference of style.
