Anno XXIII - n.1 - gennaio/marzo 1990 Le rappresentazioni degli studenti nell’insegnamento della fisica – un programma didattico (traduzione di A. Fichera)
In recent years work on students’ conceptions attracted the attention of people engaged in doing research on difficulties in learning physics. This paper shows that the origin of this kind of work can be traced back to a didactical programme starting many tears ago. […]
Anno LVI - n.2 - aprile/giugno 2023 Lente cilindrica e misura dell’indice di rifrazione dell’acqua
Geometric optics, even in the simple paraxial approximation, has significant explanatory capabilities across various phenomena. As an example of its predictive power, we present a measurement of the water refraction index by studying the focal properties of a cylindrical lens realized with readily available materials. […]
Anno XLIII - n.2 - aprile/giugno 2010 Magnetismo, effetto relativistico
Following a high-school teaching method we propose the subject-matters used in 1905 by A. Einstein to explain the relativistic effect of a magnetic field. Following the Lorentz-Einstein transforms in time and space, we show that what appears as an electric field in an inertial reference system can be seen in another relativistically equivalent system as a magnetic field. […]
Anno XXXI - n.2 - aprile/giugno 1998 Mappe concettuali come strumenti per accertare l’apprendimento in fisica
Quantitative measures of concept maps drawn by senior high-school students are shown to be useful in assessing the understanding of relationships between the concepts required for multistep problem solving. […]
Anno XXIX - n.4 - ottobre/dicembre 1996 Massa inerziale e gravitazionale: aspetti storici e didattici
In the study of Mechanics, both at secondary school and university levels, the conceptual distinction between inertial and gravitational mass is often hurriedly discussed with the aim of unifying the two quantities as soon as possible. Fundamental contributions to the clarification of the distinction between the two quantities and to increasing the accuracy of the experiments to check their proportionality were given by great physicists as Newton and Einstein, […]
Anno XXVII - n.1 - gennaio/marzo 1994 Migliorare l’insegnamento valutandone l’efficacia
The article is an introduction to Prof. Wilkinson’s paper which is published in this same issue. It discusses the writing of questionnaires to find out how students evaluate their classroom situations, and briefly compares the international and Italian researches in this field. […]
Anno LIV – n.4 – ottobre/dicembre 2021 Misure del coefficiente di temperatura di resistenza con Arduino
A Wheatstone bridge with digital readout system is discussed and used to measure the temperature coefficient of various types of resistors. The system could also be considered as a linear responsivity thermometer. […]
Anno XXVIII - n.3 - luglio/settembre 1995 Moti composti in presenza di attrito
This article analyses the rigid body motion in presence of friction […]
