由于受到应试教育教学制度的影响,传统的初中化学课程教学往往注重理论知识的灌输,考试题目的练习,教师和学生生活在枯燥的化学符号、理论文字分析的世界中,整个化学教学课堂缺乏生气,显得十分沉闷,学生感受不到化学这门自然科学的神奇,学习兴趣与探究热情都受到不良影响,学习效率也受到影响,因此,必须加大对化学实验教学重视力度,为学生营造一个良好的环境氛围,培养学生的化学实验操作能力,让学生通过化学实验的操作自然理解并掌握相关知识项目,达到 Due to the impact of exam-oriented education and teaching system, the teaching of traditional junior middle school chemistry courses tend to focus on the inculcation of theoretical knowledge, the practice of examination questions, the lack of vitality of the entire chemistry teaching class in the world where teachers and students live in dull chemical symbols and theoretical writing analysis , It is very boring. Students can not feel the magic of natural science. The learning interest and enthusiasm for inquiry have been adversely affected, and the learning efficiency has also been affected. Therefore, we must increase emphasis on chemistry experiment teaching to create a good for students Environment, cultivate students’ ability of chemical experiment operation, let students understand and master the related knowledge items through the operation of chemical experiment, achieve
