Learning skills include abilities, habits, understanding, and attitudes which are utilized to achieve learning. Students will not achieve good grades unless they properly manage their limited study time. However, it is not easy for them to organize their own study time and learn how to use it efficiently. Notably, learning analytics has not been used in previous research for time management. Learning analytics provides students with accurate data that they can use to manage their study time. Therefore, in this study, we designed a system based on a learning analytics approach with functions that allow students to make their own learning schedules and reflect on their learning behaviors. The system has visualization, calendars, and reflection functions, which are used by both students and their instructors.
