Intuitive Nonexamples: The Case of Triangles
Tsamir, Pessia; Tirosh, Dina; Levenson, Esther
Educational Studies in Mathematics, v69 n2 p81-95 Oct 2008
In this paper we examine the possibility of differentiating between two types of nonexamples. The first type, "intuitive nonexamples," consists of nonexamples which are intuitively accepted as such. That is, children immediately identify them as nonexamples. The second type, "non-intuitive nonexamples," consists of nonexamples that bear a significant similarity to valid examples of the concept, and consequently are more often mistakenly identified as examples. We describe and discuss these notions and present a study regarding kindergarten children's grasp of nonexamples of triangles.
