This paper focuses on the use of coteaching between a physics specialist and a primary science teacher in order to promote more relevant pre-service teaching. The paper reports on a project based on an eight weeks preservice physics course in which a university physics teacher and a primary science teacher cotaught a group of primary science student teachers as they worked on practical experiments and problem-solving skills in physics. The student teachers were video recorded during experimental workshops in order to follow their activities and discussions during the experiments. All the experimental workshops were followed up with a seminar, where the physics teacher and the primary science teacher watched the video recording with the student teachers in order to reflect on how concepts were communicated. After the eight weeks of coursework the physicist and the primary teacher were interviewed in order to study what they learned from the coteaching during the seminars. Five of the student teachers were interviewed in order to examine how they perceived the coteaching and how it influenced (or not) their learning of physics. The results provide insight into the effectiveness of coteaching as a way to enhance a more applicable science teaching and learning.
