This study examined the effects of mobile apps on the learning motivation, social interaction and study performance of nursing students. A total of 20 students participated in focus group interviews to collect feedback on their use of mobile apps for learning and communicative activities. Two consecutive cohorts of students in a nursing programme, each with about 200 students, were recruited for assessing their learning motivation through a survey and study performance by two tests. The results showed that the students actively used the mobile apps for studying supplementary materials as well as participating in in-class activities and clinical assessments. The students had a relatively high level of motivation for performing and learned well, but relatively low perceived satisfaction and self-efficacy with mobile learning. They showed better study performance after practising mobile learning. The results also suggest that students' perceived intrinsic value with mobile learning has to be enhanced for improving study performance.
