初中物理教学大纲中明确提出,要培养学生初步的分析、概括能力和应用物理知识解决实际问题的能力.这就要求我们教师在讲解例题或指导学生解题的过程中,充分运用分析、综合的方法,引导学生积极思维,应用学过的物理知识、规律、公式解决实际问题.现以下题为例,说明分析法的具体应用.例题:矿井里有一条斜面形状的坑道,坑道长100米,高10米,坑道顶端有一台功率为10
The syllabus for junior middle school syllabus clearly stated that we should cultivate students’ preliminary analysis, ability to summarize, and the ability to apply physics knowledge to solve practical problems. This requires our teachers to make full use of analysis and synthesis in the process of explaining examples or instructing students to solve problems. Methods, guide students to think positively, apply learned physics knowledge, laws and formulas to solve practical problems. The following questions are taken as examples to illustrate the specific application of analytical methods. Example: There is a beveled tunnel in the mine, and the length of the tunnel is 100 meters. 10 meters high, with a power of 10 at the top of the tunnel
