Background: Taiwan's higher education institutions prioritize interdisciplinary knowledge and cultural competence in cultural design, emphasizing the value of immersion in the local environment to develop cultural competence. However, challenges arise from the disappearance of traditional local lifestyles and limitations of traditional outdoor lectures such as group size and learning environment. Mobile augmented reality technology serves as a personal learning tool to overcome these challenges, enabling learners to uncover hidden knowledge in scenic locations and improving learning efficiency. Objective: The study utilized learning analytics to investigate the impact of using mobile augmented reality on enhancing learners' cultural competence. Methods: The study used both qualitative and quasi-experimental quantitative research to evaluate the effects of mobile augmented reality on cultural competence. A total of 78 third-year university students participated in the study, with 37 of them using mobile augmented reality to learn about culture. The researchers utilized both the Mann-Whitney U test and interviews to compare the effectiveness of mobile augmented reality with that of a 'real' tour guide in field courses. Results: The experimental results indicate that learners were able to continuously seek and find information about local culture through field exploration with mobile augmented reality, resulting in similar effects to those of attending a live lecture. Conclusions: It showed that incorporating mobile AR into field visits can create gamified and active learning scenarios that enhance immersion and drive active learning in local culture. The results in greater cultural knowledge and understanding, leading to the development of cultural competence in students.
