The purpose of this study is to examine how ontological becoming occurs through various events occurring during community experimentation and relationships with participants in 6 preservice early childhood teachers during the learning community experimentation process. In order to three-dimensionally describe the experience of individual existence who were in the process of becoming a constant existence in the entanglement with the learning community and various existence, the multivocality concept of postmodernism was set as a philosophical point of view of research methods and were used as a method for data collection and interpretation, as well as for composition and description of research results. As a result of the study, the existence-becoming of members started from having positive energy due to the event of a learning community encountered in life and occurred through self-understanding and thinking of members in the relationship between existences. The existence-becoming of members was entangled, connected, and created in an unpredictable encounter. In this way, it is hoped that looking deeply into the meaning of the experiences of members who participated in the learning community experiment from an ontological point of view is the role of a movement that opens up new possibilities for transitioning from preservice early childhood teachers education to being important on learning and existence itself.
