The Theory of Objectification: A Vygotskian Perspective on Knowing and Becoming in Mathematics Teaching and Learning presents a new educational theory in which learning is considered a cultural-historical collective process.

Its starting point is that schools do not produce only knowledge; they produce subjectivities too. As a result, learning is conceptualised as a process that is about knowing and becoming. Drawing on the work of Vygotsky and Freire, the theory...

This situation has not significantly changed, as most learning scientists continue to study cognition independent of emotion. In this book, the authors use cultural-historical activity theory as a perspective to investigate cognition, emotion, learning, and teaching in mathematics. Drawing on data from a longitudinal research program about the teaching and learning of algebra in elementary schools, Roth and Radford show (a) how emotions are reproduced and transformed in and...

This volume discusses semiotics in mathematics education as an activity with a formal sign system, in which each sign represents something else. The significance of signs for mathematics education lies in their ubiquitous use in every branch of mathematics.
