Mobile and ubiquitous technologies have been applied to a wide range of learning fields such as science, social science, history and language learning. Many researchers have been investigating the development of ubiquitous learning environments; nevertheless, to date, there have not been enough research works related to the reflection, analysis and traces of learners' activities in the history of ubiquitous learning environment. Therefore this paper presents a research on the design and development of a dashboard function which proposes new opportunity for ubiquitous learning. The dashboard captures, analyzes and visualizes traces of learning activities in order to promote awareness and enables learners to reflect on their own activity and helps to recall what they have learned. An initial evaluation has been conducted with 14 international students. Results indicate that the dashboard is a useful tool for self-reflection on activities and recall what learners have learned by repeated quizzes.
