Abstract: We have been developing a smartphone application to support intermittent review activities through micro-learning in blended first-time Chinese classes that combine face-to-face teaching and e-learning review. However, the results of past practice confirmed that although regular repetition is necessary in language learning, many learners often study one item only once for a short period of time just before a deadline and do not obtain the full expected effect. This paper reports on the design and development status of a UI that enables spontaneous, continuous, and natural self-regulated learning, including repetitive learning, in order to ensure learners' learning time and learning volume in this application.
