The main objective of this study was to investigate the effects of an AR mobile apps on early childhood education students' achievement of learning alphabets. In this study, a total of 60 children at the age of five and six years old from a rural kindergarten were involved. A quasi-experimental research was applied in this study. The results showed that the children in the AR mobile apps group had a statistically significant higher mean score than the regular or non-AR mobile apps group. In conclusion, children learn alphabets better by using AR mobile apps than using the regular mobile apps. Therefore, it is recommended that more studies on AR mobile apps should be conducted in early childhood education as the technology helped children to learn at the early age.
