How the process of acquiring and learning new motor skills can be enhanced is one of the basic questions in theoretical and applied movement science, rehabilitation and sport. The Differential Learning (DL) approach is mainly characterized by taking advantage, for the purpose of learning, of fluctuations that occur, without movement repetitions and without corrections during the skill acquisition process. The purpose of this study was to examine the effects of Differential Learning (DL) and Contextual Interference (CI) on the Retention and Transfer of Badminton backhand short serve. Prior to the implementation of the protocol, all participants of the pre-test were taken. Then, each group of research performed for 8 sessions according to the type of training. One day after the completion of the practice protocol, of all participants were taken the tests of Retention and Transfer. The analysis t-test indicated that there was a significant difference between the groups DL and CI in tests Retention and Transfer (p= 0.00). In fact, the results of the research show the effectiveness of the DL approach on the Retention and Transfer of Badminton backhand short serve. Based on the results of the research, the conclusion is that the DL approach is useful for learning skills, and can discover adaptive solutions by creating oscillations in the individual and helped to improve and learning skills.
