“双减”背景下促进学科理解的“化学方程式”提质增效教学策略

Teaching Strategies in Students'Learning of Chemical Equations for Improving Higher Quality and Increasing Higher Efficiency of Promoting the Understanding of Chemistry Under the Background of"Double Reduction"Policy

以大概念统领下的“化学方程式”教学为主题,分析了其中蕴含的促进学生发展的能力要素,研究了学生在理解化学方程式中存在的困难,并据此设计了系统化的学业质量评价及素养评价目标,提出了“双减”背景下促进学生学科理解的提质增效教学策略,从真实情境建议和教学活动2方面进行了阐述。

Based on the big ideas,this study analyzed the ability elements contained in the theme of"chemical equations"'and the difficulties that students have in understanding chemical e-quations.According to the above research,the author designed systematic teaching objectives,and put forward suggestions for improving higher quality and increasing higher efficiency in teaching of chemical equation under the background of"double reduction"policy,it was elabora-ted from two aspects:real situation suggestions and teaching activity strategies.
