保育者の専門性が発揮される保育の場の検討―私立F幼稚園におけるチーム保育の事例から―, 西山, 萌, お茶の水女子大学子ども学研究紀要, 9, 23, 34, 2021年06月30日, お茶の水女子大学子ども学研究会, In order to improve the expertise of ECEC teachers, it is necessary to not only consider their acquisition of knowledge and skills as an individual, but also the demonstration of such skills in an organization. In this study, we focused on team ECEC, in which all the teachers work together, and examined the kind of organization in which the expertise of teachers can be demonstrated. The method used entailed participant observation undertaken at F kindergarten. The results were as follows: First, from the analysis of the case study, it was thought that the teachers' demonstration of their expertise was the action "understanding" and "action" took place simultaneously. Next, as gleaned from the interview analysis, it was shown that team ECEC is practiced based on beliefs and systems. In addition, it became clear that the system is important for teachers to demonstrate their expertise. The system was to create a form of ECEC where children and teachers could mix, an open structure, and time for teachers to discuss with each other.
