Abstract

In this research, an educational approach to the concept of energy is proposed. It is based on the history of physics. In 1854 Hermann Hemlholtz gave a popular lecture on the recent discovery that energy is conserved. Such lecture is used as a guide to introduce the pupils within several nuances of this concept. Not much mathematics is used, so Helmholtz's work, with several additions proposed here, is an excellent guide to understanding, from a qualitative point of view, the reasons that led scientists to establish the principle of conservation of energy. At the same time, it allows us to grasp two other concepts which are fundamental in reference to energy: work and heat. This panorama will be drawn in the first section. In the second one, some more mathematical and physical details on the teaching of energy in mechanics and thermodynamics will be offered. Finally, in the Conclusion, the interdisciplinary value of a historical approach to physics education will be pointed out. Keywords: energy conservation, Helmholtz, physics history, physics education, science education

介绍能量的概念:基于物理学史的教育和概念考虑

在本研究中，提出了一种能量概念的教育方法。它是以物理学的历史为基础的。1854年赫尔曼·赫姆霍尔兹就能量守恒的新发现作了一次广受欢迎的演讲。这样的讲座是用来作为向导，向学生介绍这个概念的几个细微差别。没有使用太多的数学，所以亥姆霍兹的工作，加上这里提出的一些补充，是一个很好的指导，从定性的角度来理解导致科学家建立能量守恒原理的原因。同时，它使我们能够掌握另外两个关于能量的基本概念:功和热。这个全景图将在第一部分中绘制。在第二部分中，将提供更多关于力学和热力学中能量教学的数学和物理细节。最后，在结语部分，指出历史方法在物理教育中的跨学科价值。关键词:节能，亥姆霍兹，物理史，物理教育，科学教育
