如何加强农村初中化学实验教学,这是广大农村学校教师关心的问题,近几年,我从实际出发,进行了一些尝试,取得了一定的效果。1.加强实验基础训练。初三化学教材中有关学生实验的基础内容包括化学实验目的,要求、常用仪器、基本操作等。我首先安排了一定课时,重点讲授常用仪器名称及其主要用途。采取轮流展示常用仪器,印发主要仪器图,要求仿绘,达到个个会画仪器图的目的。
How to strengthen the teaching of chemistry experiments in rural junior high schools is a concern for teachers in rural schools. In recent years, I have made some attempts and achieved certain results. 1. Strengthen basic experimental training. The basic contents of student experiments in the third grade chemistry textbook include the purpose of the chemical experiment, requirements, commonly used instruments, and basic operations. I first arranged for a certain period of time to focus on teaching the names of common instruments and their main uses. Take turns to display the commonly used instruments, print the main instrument diagrams, and require the imitation of drawings to achieve the purpose of drawing instrument diagrams.
