The purpose with this study is to investigate how the intersubjectivity between the children and the pedagogue is displayed in large children groups in the hall. To investigate this, we have performed a qualitative study where observations and interviews have been made at three different preschools, and following questions was asked; How is the pedagogue dealing with obstacles and opportunities to co-operate together with children in large children groups in the hall. What strategies uses and develops the pedagogue in order to make the hall a place where interactions between children and pedagogues can be placed. The study takes into account Bronfenbrenner's developmental ecological system theory where is pinpointed, the relational and punctual perspective and the concept of intersubjectivity. Previous research shows that educators who is working in large children's groups experience their work as stressful and that they feel insufficient and unable to see each individual child. Research also shows that the younger children learn the best in interaction with a challenging teacher. The results of the study show that the educational work in the hall in large children's groups is first and foremost guided by the prerequisites of the educators. In order for there to be interaction between children and educators, it is necessary for teachers to work on the basis of certain strategies such as institutional arrangements. The results of the study also show that teachers' work in the hall is very vulnerable, as it is enough for an educator to be sick to cope with the conditions and thus affect the situation in the hall.
