Tipi diversi di costanti in fisica e apprendimento significativo della disciplina

Data derived from teaching experience point to some problems referred to the conceptualization of constants that appear in relationship between physical magnitudes. Some significative problems are identified. Two general hypotheses and four derived hypotheses are formulated. In order to get more information some questionnaires are prepared. The students’ answers are analysed in different groups. Some clues are identified trying to explain the observed behaviours. They are useful as a base for the proposal of teaching strategies.
