基于化学核心素养的模型建构研究——以原电池的工作原理为例

Model Construction Research Based on Chemistry Core Literacy——Through Taking Operating Principle of Primary Battery as an Example

为了建构基于化学核心素养的模型,以原电池的工作原理为例进行了教材分析、课标分析、学情分析,设立了教学目标和评价目标,明确教学重点与难点,合理设置教学流程,并安排课后习题。这样,能够培养学生利用证据推理与模型认知构建化学核心素养模型的能力,实现了对实验观及模型观的渗透。

In order to construct chemistry core literacy based model,through taking primary battery as an example,textbook,course standard and situation analysis were done,teaching and evaluation aim were set,important and difficult points were clarified,teaching process was reasonably set,and exercises were arranged.In this way,we can train the students to use evidence to infer,use model recognition to construct chemistry core literacy,and make students understand experiment and model.
