Abstract: In this study, we use augmented reality supported learning to boost motivation for learning. This study uses
augmented reality alongside 3D graphics and colors. Shape-recogniztion cards for children are used as the learning
material to discuss the Learning Effectiveness of augmented reality applied to children. The results can serve as guidence
for future mobile learning designers. This study uses two methods of teaching for two different classes to act as the
treatment group and control groups respectively. A pre-test and post-test is held for both groups. The results of this test
show that most children after using CoShaper will have learned more efficiently in terms of identifying shapes and colors.
In addition after analyzing Learning Effectiveness statistics, a high acceptance towards learning through apps is
