Teachers have always been expected to develop active and interactive methods of learning and enhance their teaching skills accordingly in daily practice. In many cases, however, they don’t have enough experience of the kind of methods nor enough time to train themselves. This study aims to explore redesigning the methods through exchanging cognitions between teaching and monitoring teachers using a mobile application, Instant Messenger, to improve their teaching skills within a limited time frame. In this paper, the process of lesson study conducted with the application in a teacher-training course was reported. As a result, it is found that getting a better understanding of teaching aims and sharing the bases of multiple interpretations on the spot are essential to make best use of differing views of teachers, which should contribute to more efficient redesign based on cognitions in class.
