Sculpture and third-dimensional training course opportunities for art teachers in secondary education evidently show important knowledge acquisitions for students seeking to become teachers. Students are found to have firsthand experience with diverse expressions and materials, a necessary learning objective. Fields of sculpture art and craft art, in particular, have a significant relation between art works and materials. Therefore, it is necessary to have a thorough understanding of the characteristics of these fields. The present study examines works and results of assignment submissions of students who attended the course, focusing on classroom practices, with the theme of public art, “Seminar in Carvings and Sculptures”, that were held by the School of Education, Hiroshima University. Furthermore, the present study found outcomes and challenges, and suggested further possibilities of public art subjects using ceramic materials.
