Biographical sketch
With a formal background in mathematics and physics, and with a life-long interest in history, philosophy and language, I specialize today in mathematics education, focusing my research on the intricacies of human learning and creative thinking.
The overarching theme of my work is the constitutive role of language. More specifically, I investigate the implications of the assumption that human thinking as a particular case of communicative activity. In my recent studies, dealing with the question of the origins of mathematical objects and with the issue of transition from operational to structural thinking (reification), I use an approach the roots of which go to semiotics and discourse analysis. The role of metaphor in the development of mathematical discourse and the issue of building a common focus in mathematical communication are among the themes on which I have been working for the last few years. These are also the subjects which have been investigated in a series of studies on learning and teaching introductory algebra I have been conducting in Israel and in Canada. The cognitive role of metaphors and, more generally, investigating cognition through discourse analysis, were the topics of my most recent graduate courses. In addition to my research work, I have been participating for many years in developing new mathematics curricula for Israeli senior secondary schools and serving as the editor of the Israeli Journal for Mathematics Teachers.
