Saltelli, rimbalzi e altre acrobazie: come coinvolgere gli studenti nello studio delle oscillazioni

Highschool students studied oscillatory motion using sensors interfaced with graphic calculators. Three kinds of activities were performed: a first activity in the school gym, an extra-curricular laboratory course and a grade 11 lab class. The potentialities of physics investigation starting from the study of phenomena in an informal context are pointed out and the advantages and problems of the use of on line acquisition are discussed.
