This research tests that if it is efficient to use learning-theory in teaching and learning of table tennis. The research adopts the way that makes comparison between a tested boy group and a collated boy group, as well as a comparison between a tested girl group and a collated girl group. It compares the skill level between tested group and collated group, as well as the difference between interest in table tennis class and learning methods, with which it analyses the effects on students given by the using of learning-theory.
