初三学生的认识水平逐渐由具体直觉占优势过渡到抽象思维占优势。他们的特点是好奇、好动、精力旺盛,求知欲望强烈。为了使学生掌握实验基本操作技能和理解化学基础知识,逐渐形成科学观点,我们对初三化学从1985年开始进行边实验一边观察一边讨论的实验教学法。这里谈个人的一点体会。初三化学教材是学生学习化学的启蒙教材,本书各章节教材都是以后学习深造的理论基础。按实验—观察—讨论教学法的需要,我注意了实验教学。在几年的不断探索中,取得了一些成绩,使初三化学的成绩连年提高。
The level of recognition of the third grade students gradually transitioned from specific intuition to predominance to abstract thinking. Their characteristics are curious, active, energetic, and strong desire for knowledge. In order to enable students to master the basic operational skills of experiments and to understand the basic knowledge of chemistry, and gradually form a scientific viewpoint, we began experimenting with the third-party chemistry while we started experimenting in 1985. Here is a personal experience. The third grade chemistry textbook is an enlightening teaching material for students to study chemistry. Each chapter of the book is the theoretical basis for later study. According to the experiment-observation-discussion of the teaching method, I paid attention to the experiment teaching. In the continuous exploration of several years, some achievements have been made, and the achievements of junior chemistry have been improved year after year.
