The technology of the IoT system components belong to the science and engineering category. However, if composition elements of the IoT system can be configured easily and used for education, students of the liberal arts might construct IoT prototype systems. Students are then expected to create ideas related to specialized fields of the liberal arts using experience obtained the construction. Creation of ideas enables the expansion of application areas of each specialized field, even involving those which are distantly related to the ICT field. This paper proposes an educational curriculum to aim at construction of an IoT prototype system that can be achieved even by students of the liberal arts, and to aim at the creation and dissemination of ideas. In this research, we applied the curriculum to lecture for students of child education and childcare courses, and evaluated the effects.
