Abstract: This study explored the use of a mobile learning device as a learning tool to enhance novice learners¡¦ reflective thinking through ¡§reflection in action¡¨ and ¡§reflection on action¡¨ on the problem-solving of the Linux Fedora installation. Instructional simulations of the Fedora system were provided through the mobile device to enhance novice learners¡¦ learning. The learner¡¦s reflective thinking was enhanced by responding to the reflection prompt and summarizing what he/she had learned while encountered a faulty action during the simulations. Learners¡¦ ¡§reflection on action¡¨ was facilitated through reflecting, sharing, and discussion using the web-based discussion forum. The results revealed that learners showed positive attitudes toward using the mobile learning device to enhance IT learning.
