Role-play is a powerful learning strategy that promotes the learners to broaden their perspectives in various learning subjects - not only in humanity but also in science. In this paper, we will introduce a new possibility of puppetry as a device to facilitate the gaining of various insights into the perspectives of others in collaborative face-to-face role-play - especially for role-play in decision making in complex and ill-structured situations. Using puppetry with multiple puppets creates a psychological distance from the player's identity, allowing the players to play various roles based on their various perspectives. The case study of the puppetry role-play shows that the players can play various roles as though in a realistic situation. The possibility of puppetry as a catalyst interface for face-to-face CSCL systems is discussed.
