Anno L - n.4 - ottobre/dicembre 2017 Il pendolo fisico: teoria, simulazione, esperimento
We propose a new tool for laboratory curricula based on computer-aided data acquisition and analysis. A pendulum coupled to a low-friction rotary sensor offers variable length, variable mass, and two different kind of damping torque: “dynamic friction” (almost constant) and “viscous” friction proportional to the angular velocity. […]
Anno L - n.4 - ottobre/dicembre 2017 Un’espressione analitica per la costante di Wien
With the help of Planck’s formula for the black body radiation, it is possible to deduce Wien’s and Stefan-Boltzmann’s laws by means of the usual mathematical methods of secondary school. In particular, we can obtain an excellent approximation of Wien’s constant in terms of the physical constants h, […]
Anno L - n.4 - ottobre/dicembre 2017 Nuovi indirizzi per l’insegnamento della fisica?
We examine some “new trends” of didactics – such as constructivism, competence, expert-level (or authentic) tests – focusing on the teaching of Physics in Italian upper secondary schools. We try to define the meaning of these terms, on the basis of texts published by experts (pedagogists, […]
