新课程背景下的初中物理教学,非常重视物理方法的应用与评价.物理方法对物理学发展的推动作用是不言而喻的.伽利略发现的实验方法奠定了近代物理的基础,伽利略所用的比较方法为牛顿第一运动定律的得出打下了坚实的基础.物理方法是物理学科异于其它学科的重要特征之一.从目前物理方法评价的情形来看,物理方法的评价多是方法名称的评价.如:为了形象地说明宇宙扩张学说,小明同学把气球吹成球形之后,在气球上点上黑点.再把气球吹至排球大小,发现黑点之间的距离增大,以此模拟宇宙演变.这里运用的物理方
Under the new curriculum background of junior high school physics teaching, attaches great importance to the application and evaluation of physical methods.Physical methods to promote the development of physics is self-evident.Galileo found experimental methods laid the foundation for modern physics, Galileo used in comparison Method for Newton’s first law of motion has laid a solid foundation.Physics is one of the important characteristics of the discipline of physics is different from other disciplines.From the current situation of physical evaluation of the situation, the evaluation of physical methods are mostly the name of the method Such as: in order to vividly illustrate the theory of the expansion of the universe, Xiao Ming students balloon blowing into the balloon, dot on the black dots on the balloon and then the balloon blown to the size of the volleyball, found that the distance between the black dots increased, in order to simulate The universe evolves. The physical side used here
