This chapter focuses on a local school development project initiatedby teachers who experienced students’ lack of engagement, passive learning, andabsence from school. In order to achieve more active learning among the students,the teachers built an active learning classroom and set out to develop teaching methodsappropriate for the new classroom. This process turned out to be more complex thanexpected and raised questions not only about the teachers’ teaching, but also abouttheir learning and more specifically about how they as a collective created transformative agency. In this chapter, we highlight how the teachers gained transformativeagency and the situations that characterized this process. Inspired by cultural historical activity theory, we pay attention to stimuli that helped the teachers to bring forthand deal with conflicts of motives that led to break-outs from the teacher-centeredteaching and thereby created transformative agency toward a classroom practicecharacterized by students’ active learning.
