Tecniche di apprendimento attivo con esperimenti dimostrativi interattivi (Interactive Lecture Demonstrations – ILD) e l’uso di risponditori individuali (clickers)

Most introductory physics students spend the majority of their time in passive and often crowded lectures. Studies show that students learn little in such classes. The results of education research have led to the design of active learning environments (often making use of computer-assisted data acquisition tools). […]

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. […]

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. […]

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?”. […]

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. […]

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, […]

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 […]

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. […]
