In this study, we conducted a statistics workshop with the aim of proposing an effective teaching practice curriculum for improving teaching practice related to statistical content based on the statistical inquiry process. As a result, it was considered effective for student teachers to reflect on their own teaching of statistical content by asking themselves how to apply the statistical inquiry process to real-life problems and conduct analysis, and by exchanging opinions with others. Of course, knowledge and understanding of the theory of statistics are necessary, but by experiencing this kind of statistical workshop, not only knowledge, but also practical understanding of statistical content can be deepened, and the difficulties felt by student teachers may be eliminated. In this way, we believe that the statistical inquiry process can serve as a perspective for analysis of each process in the problem-solving process, as well as a viewpoint from which to look at the process as a whole, and to find the significance of "thinking with statistics" from the standpoint of each learner and teacher.
