在初中物理教学中怎样联系生产实际进行讲授是我们物理专业教师长期摸索而需要解决的一个问题.过去我们在讲解基础知识范围内的物理现象时,只是通过实验把这些现象复制出来,让同学们了解现象的真实性,从而摸清这些现象的规律和结论.虽然这样的教学也是从客观的事实出发,使同学们从感性认识提高到理性认识.但是同学在学完初中物理基础知识后,仅能从实验中认识所学过的物理现象,而对实际应用的电路、电动机、变阻器等等都认识不清.尤其
It is a question that our physics teachers have long explored and tried to teach in junior high school physics teaching. In the past when we explained the physical phenomena within the scope of basic knowledge, we only copied these phenomena through experiments and let the students Understand the truth of the phenomenon, and thus find out the laws and conclusions of these phenomena. Although this kind of teaching is also based on objective facts, the students are improved from perceptual knowledge to rational knowledge. However, the students can only learn basic physics knowledge of junior middle school Learn the physical phenomena that have been learned from experiments, and understand the practical applications of circuits, motors, rheostats, etc.
