Anno XXXI - n.2 - aprile/giugno 1998 Come valorizzare un antico esperimento didattico con la tecnica MBL: la macchina di Atwood per condurre una ricerca sperimentale sul moto
Atwood’s machine is a device born in the XVIII century as an aid for teaching mechanics; a reduced and simplified version of such device still appears in physics textbooks, as an application of Newton’s second law. An Atwood’s machine interfaced to a PC by means of position and force sensors becomes a device for a detailed investigation on the motion of bodies subject to forces that change with position. […]
Anno XXXI - n.2 - aprile/giugno 1998 Comportamenti casuali di un sistema deterministico
After some brief remarks about determinism and randomness, a simulation program is illustrated which points out how chance and necessity do coexist in classical physics. Actually, a gas of N = 1000 interacting disks in a box neatly head for the Maxwell-Boltzmann distribution just in some ten collisions. […]
Anno XXXII - n.1 - gennaio/marzo 1999 Comunicazioni in rete telematica e costruzione collaborativa di concetti scientifici: le precipitazioni atmosferiche
In this paper we present some of the results of a research project, carried on since 1990, to evaluate the potentiality offered by the new information and communication technologies, to the innovation of science teaching (physics in particular) in school. Eight Italian middle school classes, […]
Anno XXIII - n.4 - ottobre/dicembre 1990 Conoscenza della Fisica all’ingresso e all’uscita dei corsi universitari di base
The article reports the results of an investigation on the knowledge of physics related to common sense patterns of knowledge of Italian students in the first year of University. The results were communicated both to the students and to the teachers of the courses. […]
Anno XLV - n.4 - ottobre/dicembre 2012 Costruire un’unità didattica secondo metodologia CLIL: testimonianza di un’esperienza
A teacher reports his experience in an integrated ‘physics plus english’ course promoted by the CLIL (Content and Language Integrated Learning) project that introduces mixed teaching of institutional courses and foreign languages in secondary schools. […]
Anno XLVII - n.1 - gennaio/marzo 2014 Dare significato alla fisica
High school pupils? interest in physics and their understanding of the subject is disappointing if the teacher follows a teaching tradition that treats the subject as a bare technique that doesn?t motivate the learners and is unable to introduce them to critical thought. […]
Anno XXXI - n.4 - ottobre/dicembre 1998 Determinazione della retta di regressione nel caso di incertezze su entrambi le variabili
The article describes a numerical method to determine the parameters of the linear regression when are present errors in both coordinates. […]
Anno XXIV - n.2 - aprile/giugno 1991 Deviazione dei gravi verso oriente
The deviation to the east of a falling body is examined in the hypothesis that the body is dropped at the equator and the distance fallen is small so that the variation of gravity with height and air resistance may be neglected. […]
Anno XXX - n.1 - gennaio/marzo 1997 Difficoltà di apprendimento in cinematica di studenti del I anno del Corso di Laurea in Matematica
The skills of freshmen mathematics majors, in interpreting graphs of basic mathematical functions, kinematical graphs and the language of motion were investigated by means of three multiple choice questionnaires with open comments. The unidimensional analyses of each student’s answers and their correlations show context-dependence of skills: in particular the malhematical abilities are not entirely transferred to the physics context. […]
Anno XXIV - n.1 - gennaio/marzo 1991 Dimostrazioni con superconduttori ad alta temperatura. (traduzione a cura di Santino Bruzzone)
Some experiments with home-made HT superconductors are reported. […]
