The purpose of this study is to design a Minecraft game where players can learn a language by negotiating meanings and constructing knowledge together with other players. In order to achieve this purpose, related theories are explored and an instructional design theory was adopted to provide a background for a game building. After the game was designed, it was implemented to test its feasibility. A further suggestion for re-design of the game as a next step was made. [For the complete proceedings, see ED601080.]
