In this technological age, learning is no longer restricted to physical books. More and more mobile devices are integrated into learning methods. In order to achieve more effective learning, augmented reality supported learning is used as well as mobile devices to boost motivation for learning and make learning more interesting. In this study, we use augmented reality supported learning to boost motivation for learning. This study uses augmented reality alongside 3D graphics and colors. Color & Shape-recognition cards for children are used as the learning material to observe, discuss, and record the Learning Effectiveness and Technology Acceptance Model of augmented reality applied to children. The results of this study show that most students had higher recognition ability towards colors and shapes when using the Color & Shape-recognition cards. After analyzing Technology Acceptance Model test data, the data shows that the fields of perceived usefulness, perceived ease of use, attitude towards using, and intention to use are all higher when learning through the app. After analyzing learning efficiency data, the data shows that all fields show a higher efficiency when learning through the Color & Shape-recognition cards.
