Constructing, seeing, and reasoning in geometry: interdependences. (Costruire, vedere e ragionare in geometria: quali rapporti?) (Italian)
Boll. Docenti Mat., No. 41, 9-24 (2000).
Geometry has always been regarded as a distinguished discipline for both the mathematical and the general education. At school it is felt as a hard subject, not only in the way of reasoning or demonstrating, but also in the way of looking at and using figures. How can one find conditions and means to make it a true learning experience for the pupils? Various types of activities are known to be induced whenever one ’does’ geometry: observing, constructing and reasoning. These are the topics this article brings to the reader’s reflection. (orig.)
