Anno XXVI - n.4 - ottobre/dicembre 1993 Un’esperienza sul campionamento di un segnale.
Exploring signal sampling techniques through an optical experiment. The reconstruction of an optical image of a simple pattern matched to a diffraction grating is proposed as an example of data analysis by digital method. Correspondence between analysis of time dependent digital signals and of spatial digital functions is outlined. […]
Anno XXVIII - n.3 - luglio/settembre 1995 Un’indagine sulle preconoscenze dei ragazzi in merito alla struttura della materia
This paper presents the results of an enquiry on the ideas about Structure of Matter initially held by secondary school students. […]
Anno XXVI - n.3 - luglio/settembre 1993 Un itinerario didattico introduttivo all’insegnamento dell’ottica
We present a recently developed project for teaching optics to 14-15 year old students. Pointing out some shortcomings of the traditional approaches, we take into account the students’ common sense “preconceptions” investigated in various inquiries. The teaching pattern we propose is rooted in everyday experience and the aim is to answer immediately questions such as: “how can we see what we see?”. […]
Anno XLV - n.4 - ottobre/dicembre 2012 Un modello idraulico del ciclo di Carnot
The performance of an ideal hydraulic engine that transfers water between two reservoirs at different heights is compared with that of a reversible Carnot engine. The interest of this analogy between thermodynamic and mechanical quantities for a Karlsruhe type of teaching approach is discussed. […]
Anno XLVI - n.4 - ottobre/dicembre 2013 Un modulo CLIL in Fisica: “La relatività ristretta di A. Einstein”. Sperimentazioni di moduli CLIL nel Liceo Scientifico “E. Fermi” di Brindisi
The teachers ran an 8 hour CLIL course in Physics, specifically looking at Einstein’s Theory of Special Relativity. The students were a final year class at Liceo Scientifico. The article explains the different stages of the project, highlighting the teaching techniques employed, […]
Anno XLVI - n.3 - luglio/settembre 2013 Un nuovo approccio all’ottica geometrica che mette in discussione la distinzione corrente tra immagine reale e virtuale
We here propose a new approach to the didactics of the so-called geometrical optics, an approach which is founded on an experimental basis and is useful in pointing out several common misconceptions. The main consequences of such a path are both the discovery of the real images formed by a plane mirror and the revision of the traditional notion of virtual image […]
Anno XXX - n.3 - luglio/settembre 1997 Un oscillatore non lineare
Non-linear physics is a fairly complex matter to handle. A physical system presenting a bifurcation, a non-linear oscillator, is described here along with the mechanical simulation of its potential, with the aim to offer a method of introduction of non-linear systems in secondary schools. […]
Anno XXXI - n.3 - luglio/settembre 1998 Una diversa soluzione del problema proposto nell’articolo “Chi ha ragione?” della rubrica “Intermezzo” de “La Fisica nella Scuola”
This article presents another solution of a problem proposed in the review (LFNS, 4,1996). […]
