In alignment with the student project–based learning framework of the experimental education program, this class designated the Hsinchu Old City District as a long-term learning and field research site and organized the "Hsinchu Old City Cultural Exploration" activity. Centered on Dongmen Market and the historical development of the old city, students designed bilingual, location-based experiential tour content, leading both partner-country youth and classmates on guided visits throughout the Hsinchu Old City area. Through on-site interpretation and interactive learning activities, participants were guided to understand Hsinchu’s urban development, local beliefs, and market culture, demonstrating the practical outcomes of experimental education that integrates local culture, international exchange, and sustainable learning.
