The paper presents the analysis of an experimental activity, based on the inquiry model, realised with 9-10 years old pupils. The experiment consists of three main phases: 1) submission of a worksheet, 2) individual interviews, 3) communication in class. The worksheet introduces the problem of the equivalence of figures with respect to their surfaces, in a context of ‘fences and sheep’. The pupil is asked to verify and to check his answers in a personal interview. The final discussion in the classroom plays a fundamental role in the experiment. The research reports a qualitative analysis of the results, with particular attention given to difficulties and misconceptions that emerged on the topic.

Abstract

The paper presents the analysis of an experimental activity, based on the inquiry model, realised with 9-10 years old pupils. The experiment consists of three main phases: 1) submission of a worksheet, 2) individual interviews, 3) communication in class. The worksheet introduces the problem of the equivalence of figures with respect to their surfaces, in a context of ‘fences and sheep’. The pupil is asked to verify and to check his answers in a personal interview. The final discussion in the classroom plays a fundamental role in the experiment. The research reports a qualitative analysis of the results, with particular attention given to difficulties and misconceptions that emerged on the topic.
