<![CDATA[This research is initiated by the constraints of static training media in physical education. The purpose is to develop and evaluate a portable rebound board learning media with adaptive angle and distance systems to optimize stroke skills for extracurricular students. The method employed is Research and Development (R&D) following the ten-stage Borg and Gall design. The representative sample was selected using a purposive sampling technique targeting students aged 13–15 with motor coordination limitations. Data collection utilized structured Likert-scale questionnaires validated by learning material and sports product design experts. The results indicate that systematic refinements, reducing the sliding rail to 45 cm and increasing board thickness to 12 mm, successfully eliminated framework vibration. This developed learning media achieved a peak empirical feasibility score of 92% from expert panels. In conclusion, the adaptive rebound board serves as a highly feasible, stable, and valid instructional tool to facilitate independent stroke automation.]]>
