The relationships between teacher and students are interdependent and rely on their mutual interaction. In the classroom, teaching involves daily face-to-face encounters between students and teachers and therefore could be considered a moral as well as an academic issue. A central question is how the teacher can establish and support a learning community in diverse classrooms where the different learners are recognized as participants, not just as recipients. In this article, a situation from a science lesson has been selected as a case to highlight/illuminate teaching as creating space for participation. The theoretical framework used in this discussion underlines participation as intersubjectively dependent. This perspective points to the ambiguity and uncertainty embedded in teaching and learning situations. It also emphasizes the importance of the teacher's role in inviting students into meaning-making processes. Special attention is paid to essential features of teaching as creating space for participation; "the act of holding back", "the act of passing on" and "the act of non-valuing". Teaching as creating space for participation is also discussed as an issue that needs greater attention in teacher education.
