The purpose of this study was to explore whether pair learning had a positive effect on robot education, and what problems should be paid attention to when using pair learning in project-based learning. We used the seventh and eighth grade students (a total of 42 participants) as the study object, through pairing way to carry out project-based learning. This study included three projects: traffic lights, maze, and line patrol. In the process of the study, teachers, assistants and students recorded the learning process according to the form designed in advance. And in the process of the project, teachers dynamically controlled the matching situation and project progress. The study results revealed that - pair learning had a positive effect on robot education, but the pair method need to be designed more precise; The difficulty of the project could be appropriately reduced to allow for sufficient time of discussion and role exchange.
