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. […]
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, […]
The working of a toy ‘chug-chug’ motor boat is described and scientifically analysed. […]
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 […]
A compact, self-contained, pre-aligned apparatus for demonstrating interference phenomena and measuring the wavelength of the light is presented. The interference fringes are displayed on a TV screen, and the measurements may be performed in a neat and clear way. Critical construction details are also given. […]
The features of the in-service teacher training course Padagogik und Fachdidaktik fur Lehrer (PFL – Austria) for science teachers, on pedagogy and subject related didactics, are described. Most important is the tight connection between the work required during the course and the teacher situation. […]
