چکیده
براساس نظریة پویایی‌های بوم‌شناختی و رویکرد غیرخطی برخاسته از آن، یادگیرنده باید برای کشف راه‌حل‌های حرکتی که متناسب خودش هستند، تشویق شود. هدف از انجام پژوهش حاضر، تعیین اثربخشی رویکرد آموزش غیرخطی بر یادگیری سرویس بک‌هندکوتاه بدمینتون است؛ براین‌اساس، 14 نفر به‌صورت تصادفی به دو گروه خطی و غیرخطی تقسیم شدند. رویکرد خطی را براساس دیدگاه سنتی و مرسوم و رویکرد غیرخطی را با بهره‌گیری از نظریة پویایی‌های بوم‌شناختی طرح‌ریزی و اجرا کردیم. متغیرهای دقت اجرا، الگوی معیار و متغیرهای کینماتیکی محاسبه شدند. یافته‌ها نشان داد که دقت اجرا و الگوی معیار بین هر دو گروه تفاوت معنادار نداشت، اما گروه غیرخطی خوشه‌های بیشتری را در هر دو مرحلة پس‌آزمون و یادداری نشان دادند که به معنی وجود دیجنریسی است. براساس یافته‌های پژوهش، رویکرد آموزش غیرخطی در رسیدن به نتایج تکلیف و خلق الگوهای حرکتی متنوع و متناسب با ویژگی‌های یادگیرندگان مؤثر است، اما ظهور الگوهای اختصاصی به عواملی چون ماهیت تکلیف، هدف و انگیزة یادگیرنده بستگی دارد؛ بنابراین، طراحی دقیق فراهم‌سازها می‌تواند نتایج بهتری را فراهم کند که برای یادگیرنده و تکلیف مناسب‌تر باشد.

چکیده [English]
Based on ecological dynamic theory and its nonlinear approach, a learner should be encouraged to explore various movement solutions to determine the most suitable for them. The purpose of this study was to determine the effectiveness of a Nonlinear Pedagogy approach in the learning of low badminton backhand serve. A total of fourteen subjects were divided randomly into two groups. The Linear approach based on a traditional viewpoint and the Nonlinear Pedagogy approach based on the ecological dynamics theory were planned and conducted. Performance accuracy scores, movement criterion scores and kinematic data were measured. The findings showed that although the accuracy of the performance and the movement criterion between the two groups were insignificant, the nonlinear group showed more clusters in both the post-test and the retention, which indicates the presence of degeneracy. The results of this study indicate that although the nonlinear pedagogy approach is effective in achieving the results of the task and creating different movement patterns that are suitable to the characteristics of the learners, the emergence of specific patterns depend on factors such as the nature of the task, as well as the purpose and motivation of the learner. Therefore, the precise design of the affordances can provide better results that are more appropriate for the learner and the task.
