化学教学中学生对比思维的培养途径探究

Exploration of the Cultivation of Students'Comparative Thinking in Chemistry Teaching

通过对两种相近或是相反的化学现象进行对比,学生可以找到物质的本质与特性。教师在化学教学中应运用新旧知识联系,引入生活实例,借助化学概念教学,科学设计化学实验,基于物质视角切入,加强课中课后联系,培养学生对比思维,让学生学会用对比思维发现与探索问题,使学生积累化学知识,培养化学学习兴趣,提高化学素养。

By comparing two similar or opposite chemical phenomena,students can find the essence and characteristics of matter.In chemistry teaching,teachers should use the connection between new and old knowledge,introduce life examples,with the help of chemical concept teaching,scientifically design chemical experiments,based on the material perspective,strengthen the connection between in class and after class,cultivate students'comparative thinking,let students learn to use comparative thinking to discover and explore problems,make students accumulate chemical knowledge,cultivate their interest in chemistry learning,and improve their chemical literacy.
