论文部分内容阅读
《圆周运动》这部分内容,不是中学物理教学的重点章节。但是这部分内容的教学,对于巩固和加深学生对力、速度和加速度等重要概念的理解,对于巩固和提高学生对牛顿运动定律的认识,对于发展学生分析物体受力情况的技能,对于培养学生运用基本概念和规律分析解决具体问题的能力,都有重要的作用。而且,在这部分内容的教学过程中:在对运动性质的正确描述和判断上,在对平衡、作用和反作用等概念和规律的认识上,很多学生往往会有不少混淆的地方;在培养学生应用抽象思维进行逻辑推理的能力上,在培养学生运用数学知识分析推导物理结论的能力上,对不少学生来说难度较大。因此,如何用好本章教材,搞好本章教学便成了一个值得探讨的问题。李明是一位物理课代表,对物理学习不满足一般的要求,渴望作深入的探讨。徐文虽然爱好物理,但是不
This part of “Circular Movement” is not a key chapter in physics teaching in middle school. However, the teaching of this part of the content is to consolidate and deepen students’ understanding of important concepts such as force, speed, and acceleration, to consolidate and improve students’ knowledge of Newton’s laws of motion, to develop students’ skills in analyzing the stress conditions of students, and to train students. The use of basic concepts and laws to analyze the ability to solve specific problems has an important role. Moreover, in the teaching process of this part of the content: In the correct description and judgment of the nature of the movement, in the understanding of concepts and laws such as balance, role and reaction, many students often have a lot of confusion; The ability of students to apply abstract thinking to logical reasoning is difficult for many students in cultivating students’ ability to use mathematical knowledge to analyze and deduce physical conclusions. Therefore, how to make good use of the materials in this chapter and do a good job in teaching this chapter has become a question worthy of discussion. Li Ming is a physics class representative who does not meet the general requirements for physics learning and is eager to explore it in depth. Although Xu Wen likes physical, but not
