The purpose of this study is to illustrate the interaction in the classroom to contribute to understanding how we can create social participation in a school class. Can we make students involved during the school day and therefore enhance their wellbeing? Sometimes students are excluded in different school situations; these events can happen consciously by other students but also unconsciously by both students and teachers. We, as teachers, need to understand not only what works in social interactions but also why it works. The study is based on video observations, which we conducted in mathematics, sports, Swedish and science on various occasions. The study´s results were produced in a discussion group where three teachers studying filmclips reasoned and reflected on different events. The result shows how teachers with very small changes in teaching, affect the students' social participation. Responsive teachers with a clearly inclusive approach enable interaction.
