How Fragile Is Consolidated Knowledge? Ben's Comparisons of Infinite Sets
Tsamir, Pessia; Dreyfus, Tommy
Journal of Mathematical Behavior, v24 n1 p15-38 2005
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 apparently been well-consolidated may become inactive and subordinate to more primitive ones. (Contains 8 figures.)
