Abstract

The use of examples is a resource that all mathematics teachers bring into play to teach mathematical content. Although the teaching methods might be very different, the exemplification they include may have some features in common and, in this paper, we present two of those features: the variation and the transparency. These two aspects examples have may be combined in a way that generalization and abstraction can be better achieved by students; in particular, we illustrate this symbiosis in the case of the study of the quadratic function.

However, different exemplifications produce also different kind of examples. In the investigation here presented, we found major differences that allowed us to identify two types of very different examples, though with the same propose and equally effective.
