教学,不能只是讲知识,更重要的是还要讲获得这些知识的方法。比值定义法是一种科学的思想方法,其核心思想就是在相同的标准下进行比较。教学,关键在于引导学生积极有效地思维。因此,对于运用比值定义物理概念的教学,必须要合乎比值定义法的逻辑思维顺序,这样才能保证教学过程条理分明,循序渐进,逐步深化,进而自然生成揭示事物本质属性的物理概念。 Teaching, can not just talk about knowledge, more importantly, but also talk about access to these knowledge methods. The definition of ratio is a scientific method of thinking, the core idea is to be compared under the same standards. Teaching, the key is to guide students to actively and effectively think. Therefore, to use the ratio to define the physical concept of teaching must be in line with the ratio of the logical definition of the order of definition, so as to ensure that the process of teaching a clear, step by step, and gradually deepen, and then naturally generate a physical concept to reveal the nature of things.
