在物理教学中,积极引导学生观察和认识物质世界,培养辩证唯物主义世界观,是中学物理教学的任务之一. 物质是不灭的,与物质不可分割的运动也是不灭的.在中学物理学中所涉及到的如电荷守恒定律、能量转化和守恒定律等,为这一客观真理提供了有力的科学依据. 本文就中学物理教学中,如何运用“守恒定律”,培养学生辩证唯物主义物质观,作一些探讨. 一、用“守恒定律”,认识世界的物质性自然界是物质的,物质既不能创造,也不能消灭,这就是物质不灭原理. 质量是物质的一个重要属性,在中学物理教材中质量被定义为“物体所含物质的多少”。质量守恒原理的提出为物质不灭原理提供了强有力的科学根据.
In physics teaching, actively guiding students in observing and understanding the material world and cultivating the dialectical materialist world view is one of the tasks of physics teaching in middle schools. Material is immortal, and the inseparable movement with material is also immortal. In middle school physics The laws of conservation of electric charge, energy conversion and conservation laws involved in this study provide a strong scientific basis for this objective truth. This article uses the “conservation law” in physics teaching in middle school to cultivate students’ materialistic views of dialectical materialism. , to make some discussion. First, use the “conservation law” to understand the material nature of the world. Nature is material, and matter can neither be created nor destroyed. This is the principle of immortality. Quality is an important attribute of matter, in the middle school physics. The quality of the textbook is defined as “how much material the object contains.” The principle of conservation of mass provides a powerful scientific basis for the principle of material imperishment.
