La conservación de la energía: un principio de toda la física. Una propuesta y unos resultados

Abstract

The conservation of energy is one of the most important physics concepts because it unifies all phenomena. In this paper we present some results of a research on the learning-teaching process of energy and its conservation in Spanish secondary education level. Analysis of the data reveal that energy conservation is introduced in mechanics and thermodynamics but not in all physics domains. The experimental results are used to develop a new approach to energy teaching.
