Resumen

Studies of teaching and learning that aim to focus on mathematical thinking generally draw on notions of what might constitute the essence of the thinking of a mathematician. I will examine research that looks at how mathematical thinking is produced in the classroom and at how different ‘forms of pedagogy have different outcomes for different groups of learners. I will report on a number of projects in which I have been engaged that address this theme. | will then consider how sociological and psychological perspectives might combine to inform research on teaching and learning mathematics.
