Using mobile technologies in education has a lot of potential to take learners outside of their regular classrooms and mediate learning scenarios that are related to real-life situations. Mobile outdoor learning could help students to establish connections between learned concepts and their everyday life. To find out if mobile outdoor learning could be used to shift students' scientific understandings and to facilitate their knowledge transfer, i.e. students use their acquired knowledge in everyday life, an action research was conducted with 158 students (age 14-16). The results indicated that students gain knowledge during mobile outdoor learning and develop a conceptual change. Furthermore, the results showed that a learning scenario focusing on a socio-environmental problem had a bigger impact on students' transformative experience towards science learning than a more biologically specific topic.
