As project-based learning becomes increasingly suitable for the learning needs of contemporary high school students, coupled with the proḀciency in multimedia education among teachers and students, exploring the practice of project-based learning in multimedia education has become particularly important. In current Chinese cultural education, the curriculum content is generally based on mainstream national textbooks, with teaching methods in a relatively subordinate position. ἀe Cultural Core Curriculum offered by Guangzhou Foreign Language School’s international program has gained widespread attention for its originality, curriculum completeness, project-based teaching, and diverse outcome presentations. ἀis study employs a mixed-methods approach involving questionnaire surveys and oral interviews to comprehensively investigate and analyze this innovative cultural curriculum, with the aim of enhancing Chinese traditional cultural education, fostering a sense of national pride and cultural conḀdence among high school students. Furthermore, the research proposes strategies and suggestions from the perspectives of curriculum content, teaching media, teaching methods, teaching process, and assessment to create a new type of cultural curriculum that is more profound, conducive to students’ cultural learning, creation, and dissemination.
