This study is a part of an industry-university collaboration project to disseminate Japanese-style education overseas. COVID-19 pandemic led to nationwide school shutdowns around the world in 2020. In the difficult settings, we have tackled developing a five-day online STEAM curriculum for young children in Indonesia that could be conducted from Japan. The theme of the curriculum is ‘vegetables’. Young children are expected to study the shape, color, and size of vegetables; parts and growth of vegetables; and vegetable cooking. They use colored papers and scissors to make paper vegetables, sing and dance vegetable songs, and tell creative stories about vegetables. These curricula are conducted for four year-old young children in Indonesia by Japanese university students, online, with the help of Indonesian teachers, onsite. The daycare & learning center is supported by Human Holdings Co., Ltd. and Human Star Child Co., Ltd. The curriculum consists of five lessons and each lesson is 30 minutes per day for five days. The theme, ‘vegetables,’ is a good example of the STEAM curriculum, especially for ‘A (Art/Agriculture)’ in the context of Asian countries and is connected to the UNDP Sustainable Development Goals (SDGs) such as Goal 1, 2 and 3 to eradicate poverty and realize a healthy sustainable world.
