基于真实情境培养高中生与生活相关的化学素养——以“金属的腐蚀与防护”为例

Cultivating“life-related chemistry literacy”for high school students based on real-world situations——Take“corrosion and protection of metals”as an example

为提高教学效率,从《普通高中化学课程标准(2017年版2020年修订)》的教学标准和考试大纲化学部分的考查标准出发,探讨从真实教学情境角度培养学生生活性化学素养。以“金属的腐蚀与防护”为例,通过引入暖宝宝生活化情境、分析暖宝宝发热情境中的铁腐蚀知识内容、联系生活中钢铁腐蚀情境延伸知识点、升级运用金属腐蚀与防护知识于港珠澳大桥的教学策略推进高中化学教学,以实现从真实情境培养高中生“与生活相关的化学素养”的目标。

In order to improve teaching efficiency,this paper intends to cultivate students’life chemistry literacy from the perspective of real teaching situations with the teaching standards of the“General High School Chemistry Curriculum Standards(2017 Edition 2020 Revision)”and the examination standards of the chemistry as the reference.Taking the course“Corrosion and Protection of Metal”as an example,it analyzed knowledge about iron corrosion through the introduction of electric warm bags used in daily life,associated the knowledge with the steel corrosion life,and extended to the application of knowledge about metal corrosion and protection knowledge on the Hong Kong-Zhuhai-Macao Bridge.This strategy promotes high school chemistry teaching and achieve the goal of cultivating high school students’“life-related chemical literacy”from real situations.
