This presentation will introduce a long-term research project on extensive reading jointly run by three different universities in Japan. We organized a reading circle in 2021, which is formed of 40 students from four departments in three different universities who volunteered to join. The project will last until 2023 and during the three years, the participants are recommended to read as many books as possible using Xreading and attend periodical meetings and group activities that are intended to raise or maintain their motivation to read. It is an educational practice as well as a research project. As an educational practice, we are interested in how we can manage the learning community to make extensive reading successful. As a research project, we are interested in what kind of psychological transformation will occur over the long term. The presentation will focus on the project scheme and the outcomes of the first year.
