物理教学一直是中学各科教学中的一个难点。在教学实践中我认为关键的问题在于:第一,让学生在实验和生活经验的基础上建立物理模型。第二,通过对物理模型的分析和再实验,总结出物理规律。第三,分析和应用物理规律。上述三点是有机联系的,在教材编排处理以及教学方法上应特别注重发挥学生的主观能动作用。下面就物理甲种本第一章“力”的教学谈点粗浅看法: 一、调查(列出)本章学生具有的基础知识和生活经验。 1.概念基础:“力的概念”(三要素),“力的 Physics teaching has always been a difficulty in the teaching of various subjects in middle schools. In teaching practice, I think the key issues are: First, let students establish physical models based on experiments and life experiences. Second, through the analysis of physical models and re-experiments, the physical laws are summarized. Third, analyze and apply the laws of physics. The above three points are organically linked, and the teaching and editing and teaching methods should pay special attention to the students’ subjective action. The following is a brief discussion on the teaching of the first chapter ”force“ of the physical species: 1. Survey (list) the basic knowledge and life experience of the students in this chapter. 1. Conceptual basis: ”The concept of force“ (three elements), ”force
