基于思维渐进模式在中学化学元素周期表教学中的应用研究

Research on the Application of Progressive Mode of Thinking in the Chemistry Teaching of the Periodic Table of Elements in Middle School

元素周期表是元素周期律的具体表现形式,反映了元素之间的相互联系的规律,对学好中学化学有着重要的指导作用,是学习的重点和难点,为了提升其在中学教学过程的效果让学生更好地掌握元素周期律,文章结合教育学、心理学的理论知识提出思维渐进模式,按照初阶、中阶、高阶分别对应中学化学元素周期表教学中“基础知识点、结构-性质的关联和粒子效应-元素特性的关联”,引导学生正确认识元素周期表的本质,为学生后续深入学习打好基础,提升学生对高中化学知识网格化学习。

The periodic table of elements is a specific form of expression of the periodic law of the elements,reflecting the law of interrelation between the elements.It plays an important guiding role in learning chemistry in middle school and is the key and difficult point of learning.In order to improve the effect of its teaching process in middle school so that students can better grasp the periodic law of the elements,this paper puts forward the progressive mode of thinking combining the theoretical knowledge of pedagogy and psychology.Students are guided to correctly understand the nature of the periodic table of elements according to“basic knowledge,structure-property association and particle effect-element property association”in the elementary,middle and advanced level teaching of the periodic table of chemical elements,which lays a solid foundation for students’further study and improves students’grid learning of high school chemistry knowledge.
