在总复习阶段,如何巩固、提高学生的实验技能,使之达到纯熟地步;如何在较短时间内把繁杂的复习内容加以安排,使知识系统化。本文就这方面的问题谈谈自己的体会。一、注意基本仪器的使用。物理实验从某种意义上讲,就是使用基本仪器来观察物理现象,测量物理量。因此正确使用物理仪器是进行物理实验的前提,也是学生应熟练掌握的基本技能之一。如:在力学中,必须会测量长度、质量,因此要求学生能够正确使用刻度尺、天平。在电学中会测量电流强度、电压、电阻,因此学生必须会正确使用
In the overall review stage, how to consolidate and improve the students’ experimental skills, so that they can reach a mature position; how to arrange the complicated review content in a relatively short period of time, so that knowledge is systematized. This article talks about your experience in this aspect. First, pay attention to the use of basic instruments. In a sense, physics experiments use basic instruments to observe physical phenomena and measure physical quantities. Therefore, the correct use of physical instruments is a prerequisite for physical experiments, and it is also one of the basic skills students should master. For example, in mechanics, the length and quality must be measured. Therefore, students are required to use scales and balances correctly. Electricity will measure current intensity, voltage, resistance, so students must use it correctly
