An issue in education refers to a topic that emerges from societal development needs, is widely recognized by the public, and requires students to both understand and act upon. Such issues are closely linked to modern life, human development, and social values, and are characterized by timeliness, contextuality, interdisciplinarity, debatability, and dynamism. In Taiwan, 19 key issues—such as gender equality education, human right education—have been incorporated into the national curriculum guidelines. This policy encourages teachers to design diverse, issue-based curricula that foster integration of knowledge and practical application.Since 2014, Taiwan’s Ministry of Education has promoted a medium-to-long-term plan for aesthetic education, implemented in five-year phases. The Pioneering Program for Cross-Disciplinary Aesthetic Education, the largest curriculum development initiative of its kind in Taiwan, emphasizes balanced integration between the arts and other academic domains. It seeks to foster collaboration among teachers in designing arts-centered curricula that are educationally coherent, inspiring, and relevant to students’ lives.Over more than 12 years, the Pioneering Program has accumulated nearly 1,700 curricular units, of which almost 500 identify music as a core subject. This study investigates the status of these music-related curricula. First, it examines their distribution across learning stages (elementary, junior high, and senior high), their integration with non-arts academic domains (e.g., Mathematics, Social Studies), curriculum types (e.g., school-based, issue-integrated), and dimensions of aesthetic literacy (e.g., art exploration and life practice, aesthetic thinking and reflective awareness). Second, through quantitative and qualitative content analysis, the study explores how issues are infused into these 500 curricular plans.Findings indicate that most cross-disciplinary music curricula are concentrated at the elementary school level—approximately four times more than at the junior high or senior high school levels. Music is most frequently integrated with languages, followed by natural science, technology, social studies, integrated activities, mathematics, and health and physical education. The majority of curricula fall into the categories of school-based and activation programs. Regarding competencies, “Artistic Inquiry and Practical Application in Life” is emphasized most, whereas “Artistic Participation and Social Action” is least represented.The five most frequently integrated issues are multicultural education, technology, information, environmental education, and international education, while the least addressed are disaster prevention, safety, legal education, career planning, and energy education.The implications are also discussed, including the need for systematic investigation into the current status of blending between issues and curricular focus, as well as their effects.
