There is evidence for recommendations to link mathematics teacher education (MTE) closely to school mathematics and to emphasize proving why rather than proving that when teaching reasoning and proving (R&P) in schools. In spite of that, we suggest not to take the implication that MTE focuses on proving why to extremes. We outline the background, framework and results of a pilot to an intervention study that seeks to address the problems of R&P in MTE. The results suggest that teachers face more problems with R&P than expected and have difficulties selecting classroom situations in need of a mathematical justification, let alone developing justifications and supporting their students’ learning of R&P. This supports our suggestion that a dual emphasis on proving that and proving why is needed in MTE
