Συντεταγμένες και ζεύγη: μια πειραματική προσέγγιση μέσα από προβλήματα, που τα επεξεργάστηκαν ομάδες μαθητών στη τάξη

Περίληψη

In this article we present an experimental work with problems on ordered pairs and functions, solved by groups of pupils of the 2d class of Gymnasium (13-14 years of age). The objective of this experiment was to find out whether, and in what extent, the children would be able to «transfer» the idea of an ordered pair, a relation or a function, from the simple (numerical-graphical) form on the plane -with which they were already acquainted- to more complicate situations and problems from everyday life. The results were generally positive, but the solutions and their formulations were at an intuitive level, in which graphical representations played a fundamental role; also children, working in groups, tend to «forget» the formal mathematical language and use more «free» expressions in their activities.
