在高中化学课中,学生自身的认知和思维局限限制了他们解决化学的实际问题,他们不能够很好地将理论与实际连在一起,这就需要教师在教学方法上进行新的设计。在这种背景下,概念图的重要作用随着新课改的提出而日渐显现出来,化学教学中对比较抽象的概念、定义以及化学关系通过图表的形式展示,能够让学生对化学知识的理解更加具体。可以说,概念图成为现在化学教学中的一种有效手段。 In the high school chemistry class, students’ own cognition and limitation of thinking limit their practical problems in solving chemistry problems. They can not well link theory with reality, which requires teachers to make new designs in teaching methods. In this context, the important role of the concept map with the new curriculum reform and the emergence of increasingly obvious, chemistry teaching more abstract concepts, definitions and chemical relationships shown in the form of charts to enable students to understand the chemical knowledge More specific. It can be said that the concept map has become an effective means of chemistry teaching nowadays.
