The state of emergency declared in April of 2020 in relation to the novel Coronavirus disease presented new challenges for three-dimensional art education. Universities were required to provide activities with practical skills and training, while infection risks were to be avoided. Universities that conducted practical skill classes of three-dimensional works such as sculpture and ceramic art explored practical class contents, preparations and teaching methods with the purpose of providing education that was equivalent to face-to-face class in terms of quality. After trial and error, online courses including practical training were conducted. The author examined the effectiveness of online classes with questionnaire surveys conducted by the Japan Society for Ceramic Art and Education. Consequently, outcomes and challenges of online practical class of three-dimensional art works such as sculpture and ceramic art were elucidated and these findings enhanced the quality of subsequent online classes.
