The purpose of this paper is to describe the design of the “Workshop Design” course in the School of Social Informatics at Aoyama Gakuin University, and to report the results of the 2022 academic year’s practice. The course has been conducted since the school’s foundation in 2008, with improving through educational design-based research over ten years. The course has been designed to provide an interdisciplinary learning environment with two pillars: “artistic activities” and “communication space.” Many opportunities for learning by crossing boundary experiences are embedded in the curriculum, such as “artistic expression and scholarship,” “various professions,” “teaching assistants’ view,” and “various backgrounds of colleagues.” In the academic year 2022, we tried to extend extra interdisciplinarity to the class by involving five faculty members who specialized in various academic fields. In this paper, after explaining the design concept of the class, five faculty members who were involved in the practice in 2022 reported their multifaceted outcomes from their cross-boundary experiences.
