摘要
以高中化学《乙烯》的教学设计为例,分析如何落实基于“宏观辨识与微观探析”化学核心素养目标,设计了生活实际的提问,分组创新微型实验,组建球棍模型,学生表演模拟反应历程等教学活动帮助学生实现从具体知识的学习到“宏观-微观-符号-本质”的化学核心观念的构建,并提出具体的评价措施。最后利用实验班和对照班检验教学效果。
Taking the teaching design of Ethylene in high school chemistry as an example,this paper analyzes how to implement the core accomplishment goal of chemistry based on“macroscopic identification and microscopic analysis”,designs practical questions in life,innovates micro-experiments in groups,builds ball-and-stick models,and teaching activities such as students performance of simulated reaction process,to help students realize the learning of specific knowledge to the construction of the chemical core concept of“macroscopy-microscopy-sign-essence”,and put forward specific evaluation measures.Finally,the experimental class and control class are used to test the teaching effect.
