基于新冠肺炎疫情背景下的项目式教学设计——揭开防疫物资中的化学奥秘

文章以“新冠肺炎疫情中使用的防疫物资”为项目主题,结合学生已有化学知识深入加工展开探究教学。通过创设真实而富有价值的情境,完成“口罩的材料学”“消毒液的原理与性质探究”“科学使用与保存消毒液”的项目任务,立足科学防疫视角,将社会实时热点与化学紧密相连,全方面多维度地落实和渗透化学核心素养,进一步提高学生正确使用化学化工产品的能力和意识。挖掘化学知识的价值功能,更好地解决生活生产中的实际问题。

This paper takes"Epidemic prevention materials used in the COVID-19 outbreak"as the project theme,and carries out exploratory teaching based on students'existing chemical knowledge.The paper,by creating real and valuable situations,completes the project tasks of"material science of masks","Research on principles and properties of disinfectant"and"scientific use and preservation of disinfectant".The study is based on the perspective of scientific epidemic prevention,closely connecting social real-time hot spots and chemistry,implementing and penetrating the core quality of chemistry in all aspects and in multiple dimensions.The aim of the study is to let students further improve the ability and awareness of the correct use of chemical products,explore the value function of chemical knowledge,and better solve the practical problems in life and production.
