基于宏观辨识与微观探析的化学学科教学设计——以高中氧化还原反应为例

Teaching Design of Chemistry Based on Macro-identification and Micro-analysis:Taking Oxidation-reduction Reaction of Senior Middle School as an Example

宏观视角具有可视性,而微观视角具有抽象性,在教学过程中,要注重学生宏观辨识与微观探析核心素养的培养。以氧化还原反应为例,引导学生通过宏观现象,对微观粒子的变化进行推导,引导学生循序渐进的探索氧化还原反应的概念及本质。这种将宏观视角和微观视角结合起来的方法,有利于对学生宏观辨识与微观探析核心素养的培养,进而提升学生的创新精神和实践能力。

.In the teaching process,we should pay attention to the cultivation of studentscore literacy of macro-identification and micro-analysis.Therefore,taking redox reaction as an example,this paper guides students to deduce the changes of micro-particles through macro-phenomena,and guides students to explore the concept and essence of redox reaction step by step.This method of combining macro-perspective and micro-perspective is conducive to the cultivation of students core literacy of macro-identification and micro-analysis,so as to improve students innovative spirit and practical ability.
