化学概念在高中化学内容中占有很大的比例,其教学质量关系着学生对化学基础知识的学习以及化学实验的操作.化学概念存在于各个单元中,将每个单元的化学内容有机串联了起来,由此可见,要想保证学生化学学习的效果,就必须加强对化学概念的教学.然而,当下高中化学老师并没有认识到概念学习对学生的重要性,也没有确立有效的教学设计思路与教学方法.对此,笔者提出了构建主义教学思路,并提出了几种教学方法,希望可以为广大化学老师提供一些参考.
The chemical concept occupies a large proportion of the chemical content of high school. Its teaching quality concerns the student’s learning of basic chemical knowledge and the operation of chemical experiments. The chemical concept exists in each unit, and the chemical content of each unit is organically connected in series. Therefore, in order to ensure the effectiveness of student chemistry learning, we must strengthen the teaching of chemistry concepts. However, current high school chemistry teachers do not recognize the importance of concept learning for students, nor have they established effective teaching design ideas. Teaching methods. In this regard, the author proposed a constructivist teaching idea, and put forward several teaching methods, hoping to provide some reference for the majority of chemistry teachers.
