“双减”政策下提高化学课堂有效性的教学研究

Teaching Research on Improving Effectiveness of Chemistry Teaching under Policy of“Double Reduction”

在“双减”政策下,教学改革要寻求发展,必须从提高教学有效性上下功夫。基于此,本研究从化学学科的学习特点出发,提出重学情、重思维、重能力的措施,并以“硫酸”的教学为例,运用了三线式的教学设计思路,优化了硫酸的教学设计并进行了教学实践,意在检验此方法能否使高效课堂、高效学习得以实现,进而为其他教师工作和学生学习提供一定的参考与借鉴。

Under the policy of“double reduction”,the teaching reform must focus on improving the teaching effectiveness to seek development.Based on this,from the characteristics of chemistry discipline study,learning,thinking,ability of the measures was brought forward,and“sulfate”teaching was taken as an example,the three lines of teaching design thinking was used,the teaching design and teaching practice of sulfuric acid was optimized,intended to test the method could make efficient classroom,efficient learning was able to realize,and then some reference were provided for other teachers and students to learn.
