The classical pendulum experiment is discussed in order to show the approximations leading to possibly significant differences between theory and experiment. The way to minimize uncertainties in the data-taking procedure is also discussed. […]
The Foucault pendulum can be an excellent teaching aid. For example, it can be used to measure the latitude of the place you live in. This article shows how the students and the entire population of a small village were involved in a physics experiment and discusses some modifications to the original design for an updated repetition of the experiment. […]
In order to inquire about knowledge and awareness of young people about the risks connected with the uses of ionizing radiation, we have submitted to various groups of first year university students a questionnaire. Results obtained are examined, also on the light of the different types of secondary school previously attended. […]
A short history of the changes brought in secondary education in Italy by increased school autonomy, with special attention to their consequences on the teachers’ role when teaching physics. […]
Physics textbooks describe electromagnetic induction phenomena with the simple calculation rule called ‘flux law’ but Maxwell’s general law of electromagnetic induction law, based on the vector potential and invariant for Lorentz’s transformations, shows that the induced emf is the consequence of time variations of the vector potential and the motion of electric charges in a magnetic field. […]
Beyond his scientific works and lectures Enrico Fermi left a lot of simple ideas and suggestions that show his unique way of applying the procedures of one science to another science. His idea of using physics to solve the mathematical problem of estimating the value of a definite integral with a sheet of paper and a scale is described and applied to the simple case of estimating π. […]
We show how the illustrations of various natural phenomena visible in Google Earth can be used in school not only for teaching geography and geology but also for introducing the physics of waves. […]
Relativity theory is seldom presented to the Italian highschool pupils. During a Master in Didactics of Physics the author experimented teaching the fundamentals of the theory to adult students in a vocational highschool. The design, the implementation and the results of the experience are described and briefly discussed. […]
Some advantages offered by the conceptual schemes of the irreversible processes thermodynamics in analysing different dissipative phenomena are summarised. The explicit time dependence of all variables and the introduction of new concepts such as the generalized fluxes and forces are the focus of a didactic approach which has been submitted to secondary school students. […]
After the introduction of Joule’s work, his paddle wheel experiment is analysed. The conceptual simplicity of this experimental apparatus makes itself a useful didactic model. Therefore its reproduction, the execution of the experiment and the possible didactic purposes will be described. […]
