Based on Ecological dynamics (ecological psychology and dynamic system), Motor learning or the acquisition of coordination is a process of searching for stable functional coordination patterns, into which a system can settle during a task or sport skills. Sport skills is a complex system and every learner has tendencies and intrinsic dynamics. This tendencies can Shape the coordination patterns of learners in dynamic context of sports. So learning process needs to takes into account this dynamics and helps the learner to develop adaptive functional behaviors. Based on the above-mentioned explanations, the present study aimed to investigate the effectiveness of a Nonlinear Pedagogy approach in learning the sports skills. Totally, ۱۴ learners were randomly divided into two groups and participated in a ۳-week intervention in order to learn the badminton short backhand serve. To this end, the linear approach was conducted based on traditional viewpoint using the descriptive methods and repetitive instructions. In contrast and Nonlinear Pedagogy approach in line with ecological dynamics theory using manipulation of task constraints especially task constraints (including equipment and rules) Planned and conducted. Performance accuracy scores, movement criterion scores and kinematic data were measured during pre-intervention, post-intervention and retention tests. The findings showed that, two groups represented no significant differences regarding the accuracy and quality of the performance. However, individuals in the nonlinear group demonstrated more clusters due to the emergence of degeneracy. In addition, the findings revealed that the nonlinear group achieved the results of the task, indicating that this approach was effective in considering the intrinsic dynamics of learners by guiding them towards the emergence of individual patterns. Furthermore, factors such as the type of task and learner motivation contribute to the emergence of these diverse motor patterns. In general, more accurate design of the affordances increases the learners accessibility and helps them to achieve better results.
