摘　　要：针对高三定量实验的复习特点,以“摩尔盐纯度的测定”为例进行基于“模型认知”核心素养培养的教学实践。对教学背景、设计思路、教学过程等方面进行研究分析,并从精心选素材,引发模型认知;高质量设问,建构模型认知;点、线、面结合,丰富模型认知等3个角度对促进学生“模型认知”素养提升的化学教学进行分析和阐释。According to the characteristics of quantitative experiment review in senior three, the teaching practice based on the cultivation of core literacy of “model cognition” was carried out by taking “determination of molar salt purity” as an example. Research and analysis of teaching background, design ideas, teaching process and other aspects, and carefully select materials to trigger model cognition;high-quality questions, construct model cognition;Combining point, line and plane, enriching model cognition and so on, this paper analyzes and explains the chemistry teaching to promote students’ “model cognition” accomplishment.

关 键 词：模型认知 摩尔盐 纯度测定 实验方案设计
