“双减”背景下数学单元教学策略探研

Exploration of Teaching Strategies for Mathematics Units under the Background of"Double Reduction"

“双减”背景下,教师一方面要提高课内教学效率,积极构建师生共同参与的高效课堂,另一方面则要落实“双减”政策要求,做好教学减负工作,为学生综合素养的均衡发展预留更多时间和空间。基于此,“双减”背景下数学单元教学要立足学生学情,夯实单元教学基础;着眼教学需求,明确单元教学目标;梳理课时内容,细化课堂教学流程;构建知识框架,促进单元知识理解;设计导学问题,驱动学生自主探究;完善评价模式,实现教学有效评价。

Under the background of"double reduction",teachers need to improve the efficiency of in class teaching and actively build an efficient classroom with the participation of teachers and students.On the other hand,they need to implement the requirements of the"double reduction"policy,do a good job in reducing teaching burden,and reserve more time and space for the balanced development of students'comprehensive literacy.Based on this,mathematics unit teaching under the background of double reduction should be based on students'learning situation and consolidate the foundation of unit teaching;focus on teaching needs and clarify unit teaching objectives;sort out the course content and refine the classroom teaching process;building a knowledge framework to promote understanding of unit knowledge;design guided learning questions to drive students'independent exploration;improve the evaluation model to achieve effective teaching evaluation.
