物理学不仅以概念和规律等科学知识揭示了自然界基本运动形式和物质结构的诸多真理,而且还以建立这种知识体系过程中所凝练和升华的科学方法推动科学的进步。因此,义务教育物理课程标准中将“过程和方法”列为三维目标之一,其目的是要求同学们在学习物理知识的同时,更要注意领悟其中的科学方法。在研究某些物理概念或物理规律时,往往要同时用到几种研究方法。如在研究“影响压力作用效果与哪些因素有关”时,同时用到了观察法(观察凹陷的程度)、转换法(用形变的大小表示压力作用效果)及控制变量法等方法。所以,在实际问题的研究过程中,我们不能限于一种方法,而要根据题意,并
Not only does physics reveal the truths of the basic forms and material structures of nature in the scientific knowledge of concepts and laws, but also advances scientific progress in a scientific way that concludes and sublimes this system of knowledge. Therefore, compulsory education physics curriculum standard “process and method ” as one of the three-dimensional goals, the purpose is to require students to learn physical knowledge, but also pay attention to comprehend the scientific method. In the study of some physical concepts or laws of physics, often use several research methods. For example, in the study of “factors that influence the effect of stress”, we used the observation method (the degree of observation of the depression), the conversion method (the effect of pressure by deformation) and the control variable method. Therefore, we can not limit ourselves to one method in the research of practical problems,
