This study investigated how to educate student teachers to develop a focus on student learning during teacher education. The designed learning environment characterized by the use of authentic contexts, authentic tasks and reflective dialogues. The study indicates that it is possible to change student teachers’ conceptions in a relative short period of time, even though there were substantial differences between student teachers. More specifically, six student teachers developed more constructivist and less transmissive conceptions as a result of the designed learning environment. The other four student teachers showed the same change in the drawings, and also developed more or maintained constructivist conceptions as shown in the metaphors, but maintained or showed less constructivist conceptions in the questionnaires.
