Anno XXXIV - n.4 - ottobre/dicembre 2001 Isolanti e conduttori nelle esperienze di elettrostatica
The difficulty that is attributed to electrostatic experiments and the little favour that these hold among many teachers generally lies in not knowing the electric properties of the materials in the conditions in which the experiments are intended to be carried out: high tension and a very small electrical charge. […]
Anno XXXIV - n.3 - luglio/settembre 2001 Studio di problemi non lineari
A one-dimensional dynamical system of 64 particles with forces between neighbors containing nonlinear terms has been studied on the Los Alamos computer Maniac I. The nonlinear terms considered are quadratic, cubic and broken linear types. The results are analysed into Fourier components and plotted as a function of time. […]
Anno XXXIV - n.3 - luglio/settembre 2001 Dentro la Scatola Nera: elevare gli standard usando la verifica in classe
The trouble with the prevalent approach to educational assessment is that we have divorced the certification of achievement and capability from the learning process. We started out with the aim of making the important measurable, and ended up making only the measurable important. […]
Anno XXXIV - n.2 - aprile/giugno 2001 Simulazione in ottica geometrica
Several papers have demonstrated that the student constructs conceptual schemes based on everyday life experience (preconcepts) constitute an obstacle for the scientific learning. So it is important to find strategies to make easy the transition from the everyday life schemes to scientific schemes. […]
Anno XXXIV - n.2 - aprile/giugno 2001 L’occhio e il cielo
This article on vision discusses the structure of the human eye, its resolving power, its coordination with the brain, peripheral vision and other details of how we detect moving and still objects. […]
