从中美新课程教材密度知识的教学进行对比,从中看出我国教材的逻辑性强、概念抽象、涉及的数学知识较多,但没有把材料和技术落实到概念的教学之中;美国教材逻辑性不强,但概念联系生活,起点低,能把材料与密度相结合,突出材料和技术的应用。希望借助对比分析改进我们的教学思想,将物理知识的教学具体化,减少概念教学的抽象化。
Comparing the teaching materials of new courses in China and the United States, we can see that the teaching materials in our country are more logical and abstract in concept, and involve more math knowledge, but they do not put the materials and technologies into the teaching of concepts. The logic of American teaching materials Not strong, but the concept of contact life, low starting point, can combine the material and density, highlighting the materials and technology applications. It is hoped that with the help of comparative analysis, we can improve our teaching ideas, make the teaching of physical knowledge concrete and reduce the abstraction of concept teaching.
