Anno XXXII - n.4 - ottobre/dicembre 1999 Il macroscopio:una versione didattica del microscopio a scansione di forza
We describe an home-made device simulating, at macroscopic level, the behavior of a scanning force microscope, that we suggest to use for didactic purposes aimed at clarify genesis and meaning of the electronic images, frequently found in textbooks. […]
Anno XXIII - n.2 (speciale: L'elaboratore nella didattica della fisica) - aprile/giugno 1990 Il microelaboratore nella scuola (traduzione di S. Pugliese Jona)
Starting from a general discussion of the role of models and the dangers of dogmas, the article deals with the prospects computers open in school education. It is shown how important it is to give pupils the possibility of exploring alternative models of reality, […]
Anno XLII - n.3 - luglio/settembre 2009 Il microscopio ottico a proiezione come modello per introdurre la microscopia elettronica in trasmissione
An optical projection microscope is used to introduce highschool students to the working of the electronic transmission microscope. The sequence of the lab activities and computer simulations is programmed in close in analogy with what actually happens when using the electronic microscope, […]
Anno XXVII - n.2 - aprile/giugno 1994 Il Mistero del forellino negativo. (traduzione da The Physics Teacher, novembre 1991, a cura di Silvano Sgrignoli)
“Negative pinholes” – black spots which are an optical reverse-counterpart for small holes – are a nice idea indeed and a good benchmark for the effectiveness of ray-tracing techniques. The article shows how an intriguing paradox raised by negative-pin-hole images can be turned into an interesting classroom activity. […]
Anno LVI - n.1 - gennaio/marzo 2023 Il moto browniano tra didattica e arte
I show how to create a chaotic sculpture starting from Brownian motion. […]
Anno XXIV - n.1 - gennaio/marzo 1991 Il moto dei corpi in un fluido viscoso: un’esperienza per valutare la resistenza del mezzo
This work describes an experiment, carried out with rather simple devices, on the quantitative study of the motion of some spheres, made of different materials, freely falling in water. We also propose a simulation program, written in Pascal language, allowing to compare the results of a theoretical model with the experimental data. […]
Anno XXXIV - n.1 - gennaio/marzo 2001 Il moto dell’altalena: un gioco antico studiato con tecnica moderna
See-saw motion is investigated using an on-line data acquisition system made of TI89, CBL, and a motion sensor (sonar). Two cases are considered: the twin-edges pivot and the round pivot. We discuss the different behaviours that lead either to strongly anharmonic or to nearly harmonic motions. […]
