Learning-theory has an apparent improving effect on students" learning the basic skill of table-tennis. In the comparison between tested group and compared group, an obvious difference appears; it also has a positive effect on students" learning interest, for it can make students keep more interest in learning; using learning-theory is able to improve students learning method of table-tennis. Based on the similar initial learning level of tested group and compared group, and through a one-term teaching experiment, apparent difference of learning method between tested group and compared group arrears, and the learning method of tested group is better than that of compared group.
