The education sector needs to improve education quality after the post-pandemic and subsequent decline in educational attainment. Additionally, there has been a heightened reliance on private education, coupled with the projected inflection point of 2070, when the global population will decline. Various solutions have been developed and implemented to support changing educational environments and teaching methods. However, despite these efforts, the problem of a widening educational gap between urban and rural students persists. This is due to difficulties accessing educational resources caused by long distances between schools, and there is an increasing demand for practical measures to make education more inclusive. In this case study, we analyzed the building and operation of a teaching-learning platform. We interviewed stakeholders to prepare a preemptive response to social issues that education will face in the future. Through this, we derived considerations for an exchange learning-based teaching-learning platform (that supports teachers' exchange learning lesson designs) and proposed a design plan platform. The results of this study are expected to minimize the learning gap between urban and rural areas, support the development of educational programs that consider students' interests, and adjust the educational difficulty to a suitable level for each student. It is also believed to help develop and utilize an AI-based, learner-customized learning platform.
