The first years of teaching are often described as 'emotionally challenging' by English as a foreign language (EFL) teachers in secondary schools in France because their professional identity and skills are still under construction. How, then, can novice teachers (NTs) be supported during this process? The present study focuses on 14 NTs…

Among the new educational tools and new ways of teaching/learning of the last 20 years, educational approaches based on constructivism are of great interest because they offer the possibility for students to build scientific concepts from experimental observations. Cooking is truly a universal topic--it can be considered a true multidisciplinary…

This article presents a new technique for performing most well-known demonstrations of wave optics. Demonstrations which are normally very hard to show to more than a few people can be presented easily to very large audiences with excellent visibility for everyone. The proposed setup is easy to put together and use and can be very useful for…

Proceeding like Newton with a discrete time approach of motion and a geometrical representation of velocity and acceleration, we obtain Kepler's laws without solving differential equations. The difficult part of Newton's work, when it calls for non-trivial properties of ellipses, is avoided by the introduction of polar coordinates. Then a simple…
