This article builds on two previous ones in which we presented the processes of construction and consolidation of one student's knowledge structures about comparisons of infinite sets, according to a recently proposed theory of abstraction. In the present article, we show that under slight variations of context, knowledge structures that have…

The processes by which conceptual knowledge is constructed during mathematical problem solving were studied, focusing on the cognitive activity of learners (i.e., the ways they elaborate, reorganize, and reconceptualize their solution activity). Underlying this research is the view that learners' mathematical conceptions evolve from their activity…

This paper describes a study of the connections between beliefs about mathematics, autonomy, and knowledge structures in mathematics. Assumptions underlying the study were (1) that students' beliefs and knowledge are constructs of the individual and play a dynamic role in the learning and doing of mathematics; and (2) that autonomy theoretically…
