This paper presented ARCode, the system that employed augmented reality (AR) to motivate and help learners with programming. Since programming is an abstract task, many need help with programming, both technically and emotionally. ARCode is the game-based learning system that shows how each command works by using AR animations, and focuses on the logical order of commands. Learners can collaborate in the real world while practicing individually in the application. In our experiment, we found that the treatment group had significantly improved on their scores for all topics except for Selection, while the control group did not. The user satisfaction survey suggested that more than 80% of users accepted our system as a useful, enjoyable, and collaborative learning system. The primary results showed the system's potential to help learners better learn programming with high motivation.
