With the increasing demand for precision and personalization in physical education, biomechanics has emerged as a pivotal discipline in enhancing the quality of sports dance instruction. This study investigates the integration of biomechanical analysis and intelligent mobile terminals into sports dance pedagogy. It first proposes a system architecture that leverages wearable devices and multimedia teaching terminals to enable real-time feedback, kinematic analysis, and personalized instructional support. Based on national curriculum standards and pedagogical theory, a hierarchical indicator system comprising 3 primary, 10 secondary, and 32 tertiary teaching strategy indicators was constructed and validated using expert consultation and Kendall’s concordance test (W > 0.75). A weighting system was then applied to rank the importance of each indicator. A case study involving 25 physical dance instructors across six universities was conducted to evaluate current teaching practices and assess the applicability of the proposed strategy framework. Results indicate that most instructors rely heavily on traditional methods such as demonstration and verbal instruction, with limited use of multimedia or theoretical integration.
