Mentoring conversations are a common aspect of teacher education. This book assesses to what extent the mentor s approach and the student teacher s relationship with his mentor influence the perception of learning in these conversations. The focus is on the student teacher s perceived learning outcomes by measuring his perceived knowledge productivity. In a comparative case-based design 12 couples of student teachers and their mentors are compared. The results show that the mentor s approach in the mentoring conversation does not significantly influence the student teacher s perceived knowledge productivity and that student teachers who have a positive relationship with their mentor have higher perceived knowledge productivity. The findings of this book indicate that the relationship between student teacher and mentor influences the student teacher s perceived learning outcomes. The book is of interest to teacher educators and educational researchers.
