笔者对阜阳市的部分中学九年级学生做了一次关于初中化学学习现状的问卷调查。通过数据分析,笔者发现,在感觉化学学习困难的学生中有86%的学生认为化学方程难以学习和掌握,从而导致了学不好化学。而九年级的化学教师在教学过程中也同样感觉到化学方程式的教学效果不理想。教学中投入大量的时间精力,但是学生还是不能有效记住方程式,不能应用化学方程式去解决问题。面对如此现状,笔者进行深入思考。影响学生掌握化学方程式的原因主要有:学生没有对化学学科产生兴趣,感觉化学枯燥,繁琐;学生的基础知识准备不足,没有掌握元素符号,化学式及相关物质的化学性质的掌握化学方程式的必须基础;没有得当的学习方法,一味死记硬背,缺乏有效的
The author of Fuyang City, part of the ninth grade students did a questionnaire on the status of junior high school chemistry learning. Through data analysis, the author found that 86% of students who felt they had learning difficulties in chemistry thought it was difficult to learn and master the chemical equation, which led to poor chemistry. The ninth grade chemical teachers in the teaching process also feel the chemical equation teaching is not satisfactory. Teaching a lot of time and effort, but students still can not effectively remember the equation, can not apply chemical equations to solve the problem. Faced with this situation, the author in-depth thinking. The main reasons that affect students to master the chemical equation are: students are not interested in chemistry, feel dry and tedious chemistry; students lack of basic knowledge, do not master the chemical elements of symbols, chemical formulas and related substances master the necessary basis for chemical equations There is no proper way to learn, blindly rote, lack of effective
