This study explore the evolving landscape of Guzheng pedagogy in the "Internet +" era, exploring the integration of traditional teaching methods with digital innovations. Applying Uses and Gratifications Theory (UGT) and social constructivist principles, the research examines how online platforms like "ChinaGuzheng.com" and Douyin cater to learner motivations and facilitate knowledge construction within a community-driven environment. Through a mixed-methods approach, the study analyzes user demographics, satisfaction data, and behavioral engagement metrics from both platforms. Findings reveal that digital platforms effectively address the diverse needs of Guzheng learners, offering flexible learning pathways, fostering social interaction, and promoting cultural preservation. However, challenges remain in terms of platform usability and catering to individual learning styles. The study proposes an integrative enhancement that merges the strengths of both platforms, creating a holistic learning experience that embraces the core principles of UGT and social constructivism. This model has the potential to serve as a blueprint for the future of Guzheng pedagogy, ensuring the instrument's cultural legacy thrives in the digital age.
