Volleyball is traditionally imparted by the coach with tutorials that have the theoretical basis in the cognitive approach. The coach illustrates with following educational tool: tutorial of Partial type, Varied, Randomized and Mental Training. It refers at motor control model of Open Loop, Closed loop and Motor Program Generalized, so the approach or interpretive key to access of knowledge is cognitive. Teaching method of physical activities and sport science is also another approach in opposite way and it is named Ecological-Dynamic. In this approach the coach does not require the tutorials but builds a setting learning environment aimed at variety of learning. It refers to the models for the motor control theory of Motor Imagery, mirror neurons system, and Degrees of Freedom by three consecutive steps: Reduction, Exploration and Capitalization of freedom degrees. Aim is to check the learning of specific volleyball skills. Methods of research is experimental and involves a team of 18 athletes, under 13. It is divided into two phases. The first one where exercises are given half an hour in each training session, the team of 18 athletes will be divided into two groups of 9, diversified for role. The athletes will be evaluated both incoming and outgoing by test the accuracy of three skills: Shot with one hand, Set and Dig. The evaluation of the accuracy are made by the coach during the match with specific descriptors. The second one monitoring through survey forms regarding the 3 skills. A) To implement new environment with exercises related to the three skills. C) change the setting. D) cooperative learning method. E) exercises of "locking" of some general movements in order to reduce the wide range of movement excursions. We expect the results in Phase II (ecological approach) are better than those of phase I (cognitive approach).And then show that the ecological approach, has better educational implications than the cognitive. In conclusions dynamic systems approach, that sees the "man" as a reality able to aerosolized thanks to a "circular randomness", is that a body left to itself will fail to produce appropriate movements even without the practice. It is therefore considered appropriate to investigate the two approaches (cognitive and ecological-dynamic) in order to improve the teaching practices in the light of the findings, considered that there are no direct comparisons documented.
